01.06.2014 BSL HARDWARE GUIDE The BSL Hardware Guide describes how to connect and setup various signal electrodes, transducers and other devices for use with the Biopac Student Lab System using an MP acquisition unit and includes sections that detail different applications and uses for the Biopac Student Lab PRO System. HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com MP ACQUISITION UNITS MP36/35 Four Channel Data Acquisition System MP45 Two Channel Data Acquisition System This document covers the following information for the MP36/MP35/MP45 Data Acquisition Systems: Symbols – page 1 Compliance/Safety – page 1 Input devices/Sensor Connections – pages 1-2 Front and Back Panels – pages 2-4 Specifications – page 5 Pin-Out Diagrams – page 6 BSL System Core Packages – page 7 Lesson Hardware Guide – page 8 BSL Lesson Descriptions – pages 9-11 The MP data acquisition unit is the heart of all Core Packages. The MP Unit has an internal microprocessor to control data acquisition and communication with the computer. The MP Unit takes incoming signals and converts them into digital signals that can be processed with the computer. There are analog input channels (four on MP36/35 units, two on MP45), one of which can be used as a trigger input. The MP Unit must be connected to the computer and electrodes, transducers, and/or I/O devices must be connected to the MP Unit. Users are suggested to take a few minutes to become familiar with the MP Unit prior to making any connections.

The MP36/35/45 is designated as Class I Type BF medical equipment EMC The MP36/35/45 satisfies the Medical Electromagnetic Compatibility (EMC) Test Standards affiliated with IEC60601-1-2. Types of Input Devices There are three types of devices that connect to the MP36/35 and MP45: electrodes, transducers, and I/O devices. Electrodes are relatively simple instruments that attach to the surface of the skin and pick up electrical signals in the body. BIOPAC Hardware | MP36/35/45 | Page 1 - 11 Updated: 12.23.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com Transducers, on the other hand, convert a physical signal into a proportional electrical signal. Input/Output devices (I/O for short) are specialized devices like pushbutton switches and headphones. Simple Sensor Connectors Regardless of the type of device connected, every sensor or I/O device connects to the MP36/35 using a “Simple Sensor” connector. Simple Sensor connectors are designed to plug only one way into the MP unit—no need to worry about plugging things in upside down or into the wrong socket! Electrodes, transducers, and the pushbutton switch all connect to the channel input ports on the front panel of the MP36/35 and MP45. Headphones and the stimulator connect to the “Analog out” port on the back panel of the MP36/35 and to the headphone jack on the top of the MP45. MP36/35 only: A digital device may connect to the “I/O Port” on the back panel MP36/35 only: A trigger device may be connected to the “Trigger” port on the back panel. Front Panel Front Panel, MP36/35 The front panel of the MP36/35 has an electrode check port, four analog input ports, and two status indicators. Electrode Check The Electrode Check port is a diagnostic tool used with the BSL PRO software to determine if the electrodes are properly attached to the subject. The MP45 does not have an Electrode Check port. Use BIOPAC’s EL-CHECK standalone electrode impedance checker to measure electrode/skin contact. MP45 is CH 1 and CH 2 only. Input Ports: CH 1, CH 2, CH 3, and CH 4 The 9-pin female analog input ports on the MP acquisition unit are referred to as Channels. There are four on the front of MP36/35 Units and two on the MP45. The Biopac Student Lab Lessons software will always check to see that the proper sensors are connected to the appropriate channel. Status Indicators Busy—indicator is activated when the MP36/35 is acquiring data and also during the first few seconds after the MP36/35 is powered on to indicate that a self-test is in progress. (When the MP36/35 passes the power-on test, the Busy light will turn off.) Power—status indicator is illuminated when the MP36/35 is turned on. Ready—status indicator is illuminated when the MP45 is plugged in and communicating. BIOPAC Hardware | MP36/35/45 | Page 2 - 11 Updated: 12.23.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com Back Panel Back Panel, MP36/35 The back panel of the MP36/35 has an analog output port, a USB port, an I/O Port, a Trigger Port, a DC input, a fuse holder, a power switch, and the unit’s serial number. The back panel of the MP45 has a USB cable and headphone port. Analog Out Port – Low Voltage Stimulator There is one 9-pin male “D” analog output port on the back of the MP36/35 that allows signals to be amplified and sent out to devices such as headphones. On the MP36, Analog Out is built-in low voltage stimulator. Not available for MP45. USB Connection The MP36/35 connects to the computer via a USB Port, located just below the word USB. Uses a standard USB connector. Should only be used to connect the MP36/35 to a PC or Macintosh. The MP45 USB cable is a full-speed USB connector and should only be used to connect the MP45 to a PC or Mac USB port. Headphone Output Accepts a standard (1/4” or 6.3mm) stereo headphone jack; functional for MP36 and MP45 only. I/O Port (MP36/35 only) Accepts a DB 25 Female connector. Input/Output port used to connect digital devices to the MP36/35. Trigger Input (MP36/35 only) Accepts a male BNC connector. Input port used to send trigger signals from another device to the MP36/35. MP system external trigger inputs are TTL compatible—this means that one needs to send the external trigger input 0 volts for a TTL low and 5 volts for a TTL high. The external trigger inputs are equipped with internal pull-up resistors—this means that they automatically sit at TTL high, if left unattached. This is a common and helpful implementation, because all one requires to implement an external trigger is to pull the external trigger input low. This implementation is typically performed with an external switch placed between the external trigger input and ground. When the switch is closed the external trigger input is pulled to TTL low. When the switch is opened the external trigger input is pulled back (by the internal pullup resistor) to TTL high. BIOPAC Hardware | MP36/35/45 | Page 3 - 11 Updated: 12.23.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com To sync several MP systems together, so that one external trigger can start all the MP systems simultaneously: 1. Connect all the MP systems grounds together. 2. Connect all the MP systems external trigger inputs together. 3. Place a switch between any MP system external trigger input and ground. When the switch is pressed, all the MP systems that are connected together will be triggered simultaneously. DC Input (MP36/35 only) Use the DC Input to connect a battery, AC/DC converter or other power supply to the MP36/35. The power supply requirements for the MP36/35 are 12 VDC @ 1 Amp. Only use the AC300A power adapter with the MP36/35. The AC300A is a 12 VDC @ 1.25 Amp power supply adapter that can connect to any mains rated as 100-250 VAC @ 50/60Hz, 40VA. The receptacle is configured to accept a “+” (positive) input in the center of the connector and a “-” (negative) input on the connector housing. Fuse Holder (MP36/35 only) The fuse holder contains a fast-blow fuse that helps protect the MP36/35 from shorts on its power, analog, and digital I/O lines. The MP36/35 uses a 1.0 amp fast-blow fuse. To remove the fuse, use a screwdriver to remove the fuse cover located below the word Fuse. Power Switch (MP36/35 only) ON position — powers up the MP Unit OFF position — cuts the flow of power Cleaning Procedures Before cleaning, be sure to unplug the power supply from the MP36/35 or unplug the MP45 USB cable from the computer. To clean the MP36/35, use a damp, soft cloth. Abrasive cleaners are not recommended as they might damage the housing. Do not immerse the MP36/35 or any of its components in water (or any other fluid) or expose to extreme temperatures as this can damage the unit.

BSLSTMB BSLSTMA Lab set up note Placing the BSLSTMA/B unit too close to MP3X hardware can result in data distortion of the BSLSTMA/B pulse width signal; the distortion is more apparent at higher sampling rates. NEVER set the BSLSTMA/B atop an MP3X Position the BSLSTMA/B away from the MP3X to reduce the signal distortion Note The older “BSLSTM” uses dial reading and a flip range switch. The same guidelines and cautions described here apply, except when noted. The BSLSTM Stimulator works in conjunction with the Biopac Student Lab System to allow precise stimulus pulse outputting. Use the BSLSTM and the BSL PRO to perform a wide array of measurements, such as: Twitch sub-threshold & threshold Maximum twitch responses Single twitch, summation Muscle tension/length vs. force Tetanic contraction Fatigue Velocity Nerve conduction STIMULATOR PULSE DEFINITIONS Pulse width The time that the pulse is in the non-zero or active state. Delay before first pulse The initial delay from the start of acquisition to the start of the first pulse. Repetition period The time between pulses, as measured from the start of one pulse to the start of the next pulse. This is the inverse of the Pulse rate. Pulse rate The number of pulses that occur in a one-second interval, expressed in Hz. The Pulse rate relates to the Pulse period as follows: BIOPAC Hardware | STIMULATORS MP3X | Page 1 - 9 Updated: 2.27.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com Pulse rate (Hz) = 1000 / Repetition period (milliseconds) Also called — Pulse frequency Repetition rate Events per second Pulse Repetition Use when referring to either Pulse rate or Pulse period. Pulse level The amplitude of the pulse, expressed in Volts. The output of the BSLSTM is 0 Volts when the pulse is not active. Number of pulses The number of successive pulses that will be sent out at the selected Pulse Width, Pulse Rate, or Pulse Period, and Pulse Level. FRONT PANEL TERMINOLOGY BSLSTMA/B — Digital Display & Keyed Switch BSLSTM — Dial Reading & Flip Switch Range control Establishes the stimulus pulse output level range in Volts (0-10 Volts or 0-100 Volts). BSLSTMA/B key control: Turn right to select a range of 0-10 Volts. Turn left to select a range of 0-100 Volts. Remove the key for added safety and control. BSLSTM switch control: Flip down to select a range of 0-10 Volts. Flip up to select a range of 0-100 Volts. If the Range is changed before recording begins, the Preset must also be changed (under the “Setup channels” option of the MP3X menu) in order to maintain direct Level recordings. If the Range is changed during recording, the user should manually enter a software marker to note the change (by holding down F9 on a PC or Esc key on a Mac). The pulse Level could then be determined by (mentally) moving the decimal place to the right or left, depending on how the Range was changed. Reference BSLSTMA/B only: Refers to the pulse width of the signal on the Reference Output (on the back panel). Actual reflects the actual output width. Fixed (15 ms) establishes a pulse width of 15 ms, regardless of the actual pulse width. The Reference control only affects the pulse width; in either case, the pulse level reflects the actual output level. Level is used in conjunction with Range to set the stimulus pulse output level. BSLSTMA/B digital display: Turn the Level control (right to increase, left to decrease) to establish the desired Level, as indicated on the digital display. BSLSTM knob dial: The Level knob has a “Major scale” and a “Minor scale” which indicate the voltage level as shown below: Range switch Major scale Minor scale 0-10V Volts Volt / 10 0-100V Volts x 10 Volts Level Turning the Level knob clockwise increases the voltage level, and turning it counterclockwise decreases the voltage. In the following close-up of the Level knob, the BIOPAC Hardware | STIMULATORS MP3X | Page 2 - 9 Updated: 2.27.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com level reads 5.1 Volts (Range 0-10V) or 51 Volts (Range 0-100V). As shown in the following diagram, the indicator mark is between the two dials. Stimulus output Pulse indicator Power indicator Close-up of “Level” adjustment knob Stimulus pulse output for connection to external electrodes or other devices. This is a standard BNC style connector. LED flashes when the stimulus pulse is active: BSLSTMA/B = red. BSLSTM = green. Activated when the DC adapter is plugged in and the power switch on the back panel is turned ON. BSLSTMA/B: The LCD display is activated. BSLSTM: LED indicator lights green BACK PANEL TERMINOLOGY Power switch Rocker switch for turning the BSLSTM power ON and OFF. Fuse holder If the fuse blows and must be replaced, use a screwdriver to open (counterclockwise) and close (clockwise) the fuse cap. Socket for BIOPAC DC adapter. DC Input Trigger cable Connects to the Analog Out connector on the back of the MP3X acquisition unit. The MP3X sends the Pulse width and Pulse rate information via this cable. Manual Test button Used to diagnose problems with the BSLSTM stimulator unit. When the Trigger and Reference Output cables are disconnected from the MP3X , the Manual Test button can be used to initiate a stimulus with a fixed pulse width of 2.5 milliseconds. Reference Output Cable The stimulus marker output is labeled Reference Output on the back panel of the BSLSTM. This output cable connects to any of the four channel inputs (CH1, CH 2, CH 3, or CH 4) on the front of the MP3X acquisition unit. The output cable carries the stimulator marker pulse to the MP3X. The marker pulse has a fixed pulse width 15ms and is generated each time the stimulator generates a pulse. BSLSTMA/B: Use the front panel Reference switch to select Actual or Fixed. BSLSTM has a fixed pulse width of 15ms, selected so that the MP30 can capture the pulse with a sample rate as low as 100 samples per second. If the BSL PRO software has been setup correctly, the amplitude of this marker will reflect the Level knob setting on the BSLSTM. See the Range switch section for information on how this reading can be affected. BIOPAC Hardware | STIMULATORS MP3X | Page 3 - 9 Updated: 2.27.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com Calibration The “Reference Output” signal from the BSLSTM must be calibrated to ensure accurate results. 1. Choose the correct menu > Setup Channels). Preset (via MP3X For example, if using the BSLSTMA/B, don’t choose a “BSLSTM...” Preset. Also, make sure the Preset matches the Voltage Range that will be used (0-10V, or 0-100V). 2. With stimulator connected and ON, turn the Level control counter-clockwise until the display reads 0 (or as close to 0 as possible). 3. Get into the Scaling window for the Reference Output channel (via MP3X menu > ). > Setup Channels > 4. Press the Cal1 button to get the signal representing 0V out of the stimulator. 5. Add the Input value found with Cal1 to the Input Value displayed for Cal2. For example, if “Cal1” is pressed and provides an Input Value of .255 mV, add the number .255 mV to the existing 50 mV and manually enter the total value of 50.255 mV for Cal2 Input Value. Note: Even if the Cal1 Input Value is negative, it must still be “added” to the number for Cal2 (which essentially subtracts it) to arrive at the proper value. 6. Click OK to close out of the Scaling window and then close out of the Setup Channel window. The system is now ready to record. 7. Optional: Save the setup as a Graph Template to save these new scale settings. As long as neither the MP3X nor stimulator changes, the calibration should not need to be repeated. BIOPAC Hardware | STIMULATORS MP3X | Page 4 - 9 Updated: 2.27.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com CONNECTING THE BSLSTM TO THE MP3X 1) Turn the MP3X unit OFF. 2) Confirm that Power switch on the back of the BSLSTM is in the OFF position. 3) Set the Range on the front of the BSLSTM to 0-10V. 4) Set the Level to 1 Volt. BSLSTM: 1 Volt is set when the Major Scale (top number) is 1 and the Minor Scale (lower number) is 0. 5) Plug the Trigger cable (female DB9 connector) from the back of the BSLSTM into the Analog Out port (DB9 Male connector) on the back of the MP3X. 6) Plug the Reference Output cable (Male DB9 connector) from the back of the BSLSTM into an open channel input port (DB9 female connectors: CH 1, CH 2, CH 3, or CH 4) on the front of the MP3X. 7) Plug the 12 Volt DC adapter into the wall. 8) Mate the DC output connector on the end of the adapter cable to the DC Input socket on the back of the BSLSTM. Make sure the connector is pressed in completely. 9) Plug the stimulator electrode assembly into the BNC connector on the front of the stimulator, labeled Output on the BSLSTMA/B and Stimulus Output on the BSLSTM. 10) Place the BSLSTMA/B unit away from the MP3X. Placing the BSLSTMA/B too close to MP3X hardware can result in data distortion of the BSLSTMA/B pulse width signal; the distortion is more apparent at higher sampling rates. NEVER set the BSLSTMA/B atop an MP3X. Position the BSLSTMA/B away from the MP3X to reduce the signal distortion.

The BSLSTM can output lethal levels of energy! Always set the Level to “0” Volts prior to connecting the stimulator electrodes to the subject. Increase the Level adjustment slowly until a response is noted. Never increase the Level more than necessary to obtain the desired response. The BSLSTM should only be used under direct supervision of an Instructor. Never place any stimulator leads in the mouth or any other body orifice. To prevent a “Ground loop,” the Ground of the stimulator electrode and the Ground of the measuring electrode(s) must always be connected to the same location. Use the HSTM01 Human Stimulation Electrode for human stimulation. To prevent a current path that goes across or through the heart, the stimulator electrodes and the measuring electrodes should always be in close proximity. For example, if making measurements on an arm, the stimulator electrodes and measuring electrodes — including the ground electrodes — must be on the same arm. Any other electrodes or transducers that make electrical contact with the body should not be connected while the stimulator is connected.

This fully shielded cable assembly permits high-resolution recording of biopotentials. Each lead set has three pinch leads designed to snap directly onto standard disposable electrodes (such as the EL500 series electrodes). Each pinch lead is 1 meter long and terminates in a yoke connected to a 2-meter cable. This is the general-purpose electrode cable used for almost all applications requiring the use of electrodes. These cables are used to connect the disposable electrodes that are placed on the surface of the skin to the MP3X/4X unit. Depending on where electrodes are placed, they can measure muscle contraction, heartbeats, or even brainwaves. One end of the SS2L cable has a Smart Sensor connector on it that connects to the MP3X/4X and the other end splits into three smaller cables. Each end of the smaller cables is fitted with a pinch connector that clamps onto electrodes. SS2L and SS2LA are discontinued products. SS2LB is the current product offering.

Two Ag-AgCl electrodes are mounted in individual, ergonomically designed, polyurethane housings for improved contact. They attach to the fingers by a Velcro strap or can be taped to any other part of the body. The electrodes have a 6 mm contact area with a 1.6 mm cavity to accommodate electrode gel (GEL1, GEL101, or the preferred recording gel). The non-polarizable electrodes are shielded to minimize noise interference and improve recordings. These electrodes are different from standard SS2L electrodes in that they have built-in, reusable electrodes on the end, the electrodes are specially designed to fit around the tip of a person’s finger, and the electrodes measure only one type of signal—the EDA. See the SS57L EDA (GSR) Lead for a disposable electrode option USAGE RECOMMENDATIONS Setup - There must be good electrical connections between the skin and the electrodes for EDA to work properly. Gel - When using GEL101 isotonic gel it is important that the gel has a chance to be absorbed and make good contact before recording begins. Accordingly: 1. Apply GEL101 to the skin at the point of electrode contact and rub it in. 2. Fill the SS3LA electrode cavity with GEL101. 3. Attach the SS3LA electrode to the subject. 4. Wait 5 minutes (minimum) before starting to record data. Presets - BSL PRO software includes two EDA presets: Electrodermal Activity (EDA), 0 - 35 Hz; requires calibration—see details below Electrodermal Activity (EDA) Change; no calibration required To calibrate the SS3LA using the Electrodermal Activity (EDA), 0 - 35 Hz preset: 1. Prepare two 1% calibration resistors; 100 kiloohm and 1 megaohm. Insulate the resistor using clear tape such that when held, the fingers will not directly contact the resistor leads. 2. Place the 1 megaohm resistor such that one resistor lead contacts one electrode pad and the other resistor lead contacts the opposite electrode pad. 3. From the Scaling dialog box, set the Cal1 Scale value to “1” and click Cal1. 4. Repeat step 2 using the 100 kiloohm resistor. 5. From the Scaling dialog box, set the Cal2 Scale value to “10” and click Cal2. Gain - verify the Gain setting of the SS3LA: 1. From the Scaling dialog box, set the Cal1 Scale to "0" and click Cal1. 2. Set the Cal2 Scale to 5Mho/V and the Input voltage to 1 V, and then close out of the Scaling dialog box. 3. Insulate a 100 kiloohm resistor and place it from electrode pad to electrode pad (resistor must be insulated from fingers). 4. Perform measurement with electrode-resistor setup. BSL PRO should produce a reading of 10 microsiemens (older presets may use micromhos units label). *SCR - Use an Expression calculation channel to take reciprocal of conductance, and then apply proper scaling. Tip To detect a good signal, subjects should have a little sweat on their hands (not a lot, but enough so that their hands are not completely smooth or cold). If subjects wash their hands just prior to the recording or if they have been sitting in a cold room, then they must do something to activate the sweat glands before beginning calibration or recording. If subjects begin with colder hands, the scale will be diminished and the signal will be easily saturated once they “warm up” during the lesson.

The electrode cavity must be left clean and dry. If GEL is left in the cavity, it will act as insulation preventing electrical contact with the skin, and the Ag-AgCl electrode disk could degrade quickly with time because the electrode surface is somewhat porous to promote good conductivity to the GEL. To clean the reusable SS3LA, use a cotton swab or toothbrush with tap water. Use Hydrogen Peroxide solution (2-3%) to brighten electrode surface (optional) or to sterilize the electrode. Do not place the electrode in solution, but simply clean the electrode surface using a cotton swab. Dry the electrode off completely before storage. Use any lab cleaner with pumice (such as Ajax) with a cotton swab or toothbrush to remove any dark residue from the electrode surface.

When the TSD200 is attached to the skin, the infrared light is modulated by blood pulsing through the tissue below. The modulated, reflected light results in small changes in the resistance of the photo resistor, which yields a proportional change in voltage output. The TSD200/SS4LA includes a shielded 2-meter cable and a stretchable Velcro® strap for easy attachment to the fingers, or it can be taped to other body parts. The TSD200/SS4LA can also be placed on other body locations by employing ADD208 adhesive disks to hold the transducer in place. Use the TSD200C ear clip transducer for easy attachment to the ear. Place the transducer around the finger and adjust the Velcro® closure to provide only slight tension. Blood density readings can vary considerably depending on transducer location and tension changes. The TSD200 connects to the PPG100C as follows (See also: PPG100C for a diagram): TSD200 Lead PPG100C Red lead +VSUP Black lead GND Purple or Blue lead INPUT The SS4LA plugs directly into the MP3x or MP45. CALIBRATION The TSD200/SS4LA does not require calibration. TSD200C PHOTOELECTRIC PULSE PLETHYSMOGRAPH WITH EARCLIP The photodetector operates via incident photons, from an IR transmitter, impacting an IR detector. The incident photons result in a proportional passage of electrons in the detector. The IR detector operates like a photoncontrolled current source. The transducer incorporates an appropriate clipping range, with linearity insured for arbitrarily low levels of reflected light. For the expected magnitude of incident infrared light, the photodetector operates in a linear fashion. Situations have not been encountered where the detector is operating non-linearly (near saturation). The TSD200C transducer operates with the PPG100C amplifier to record the pulse pressure waveform. The TSD200C consists of a matched infrared emitter and photo diode, which transmits changes in infrared reflectance resulting from varying blood flow. The ergonomic housing design improves contact with the subject and helps reduce motion artifact. The TSD200C is primarily designed for ear attachment and comes with a shielded 3-meter cable and ear clip.

This transducer is useful for determining how deeply someone is breathing and for calculating the person’s breathing rate or respiration rate. The transducer is a strain assembly that measures the change in thoracic or abdominal circumference. The strap presents minimal resistance to movement and is extremely unobtrusive. Due to its novel construction, the SS5LB can measure extremely slow respiration patterns with no loss in signal amplitude while maintaining excellent linearity and minimal hysteresis. The respiratory effort transducer has a 2meter flexible lightweight cable. The center plastic housing protects the delicate sensor within. The transducer is attached by a fully adjustable nylon strap, which allows the transducer to fit almost any circumference. To attach the nylon belt to the transducer, thread the strap through the corresponding slots on the sensor assembly. Place the transducer around the body at the level of maximum respiratory expansion (generally about 5cm below the armpits). At maximum expiration, adjust the strap so there is slight tension to hold the strap around the chest.

Volume measurements are obtained by integrating the airflow signal. The airflow transducer is lightweight, easily held in one hand, and has a removable head for sterilization and replacement. For reasons of hygiene, it is important that only one person use each disposable mouthpiece and disposable filter. SS11LA needs 5-10 minutes to warm up; during this time, the baseline offset changes slightly. The SS11LA/TSD117 airflow transducers include an optically clear detachable flow head (RX117) for easy cleaning and inspection. As the detachable flow head is snapped into the transducer handle, the flow head plugs directly into an integral, precision low-differential pressure transducer. Accordingly, the transducers will output an electrical signal proportional to respiratory flow. Use with the AFT22 NonRebreathing “T” valve for low dead space requirements. The transducers connect to industry standard bacteriological filter AFT1 with disposable mouthpiece AFT2 or AFT13 filter and mouthpiece with AFT11H coupler. The RX117 detachable flow head can be cold sterilized, autoclaved (220 F max), or placed in a dishwasher. For airflow and lung volume measurements, use the airflow transducer with the AFT2 mouthpiece and the AFT1 bacterial filter. For measurements of expired gases, use the airflow transducer with the AFT22 non-rebreathing T valve with AFT10 facemask and the AFT15A or AFT15B mixing chambers. All connections can be performed with AFT12 (22mm ID) tubing and AFT11 series couplers. Please note the following: a) The bacterial filter and mouthpiece are disposable and are “one per person” items. Please use a new disposable filter and mouthpiece each time a different person is to be breathing through the airflow transducer. b) For more effective calibration, use a bacterial filter between the calibration syringe and the airflow transducer.

Also, be sure not to remove the airflow transducer assembly from the mouth during the recording. All air leaving or entering the lungs must pass through the airflow transducer during the lung volume measurement. BIOPAC Hardware | SS11LA & TSD117 | Page 1 - 7 Updated: 12.2.2013 info@biopac.com support@biopac.com www.biopac.com HARDWARE GUIDE Use the following measurement procedure for determining lung volume: 1. 2. 3. 4. 5. Breathe normally for 3 cycles (start on inspire) Inspire as deeply as possible Return to normal breathing for 3 cycles Expire as deeply as possible Return to normal breathing (end on expire) Data Processing When integrating the collected data to determine lung volume, it’s important to integrate from the starting point of the first inspire, to the end point of the last expire. Before integration, the mean of the selected (airflow) data must be determined and then subtracted from the record. This process insures that the integral will have the same starting and ending point. Calibration For Medium-Flow Pneumotachs 1. Syringe Calibration Vertical Orientation Calibration Syringe Bacterial Filter Air Flow Transducer After the calibration process, please remove the calibration syringe and attach a new bacterial filter and mouthpiece to the airflow transducer. It’s very important that each individual use his/her own mouthpiece and bacterial filter. Place the narrow end of the bacterial filter and mouthpiece assembly into either side of the airflow transducer. Airflow data can now be recorded. For best results, hold the airflow transducer vertically. 2. Mathematical Calibration The transducer can be roughly calibrated without using the calibration syringe. Using the transducer’s nominal output of 60µV per liter/sec (normalized to 1 volt excitation), the following calibration factors can be entered in the software Scaling window. Scaling Factors for Rough Calibration of the airflow transducer The following equation illustrates why 0.12 volts maps to 1.00 liter/sec: Calibration Constant • Amp Gain • Amp Excitation = Scale Factor Thus 60 µV/[liter/sec] • 1000 • 2 Volts = 0.12 V / [liter/sec] Data can now be collected directly. Prior to analyzing the data, remember that there will always be some offset recorded in the case of zero flow. Note: With the TSD117 and MP150/100 system, it’s possible to largely trim this offset out, using the ZERO potentiometer on the DA100 amplifier, but some residual will always remain. BIOPAC Hardware | SS11LA & TSD117 | Page 2 - 7 Updated: 12.2.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com To remove residual offset after the flow data has been collected, select a portion of the baseline (zero flow reading) and calculate the mean value using the popup measurements. Subtract this mean value from the raw data to obtain a mean corrected flow signal. Now, the integral of the mean can be calculated as shown in this graph In this case, a 600ml-calibration syringe was used to check the rough calibration of the airflow transducer. The rough calibration indicates a syringe volume of about 550ml, so this method may only be expected to be accurate within ±10% of the real reading. Flow Measurement and Volume Calculation To achieve a more exact calibration, start with the above scaling factors and then boost or drop them slightly as indicated by the rough calibration. In this case, if the map value correlating to 0.12 volts were boosted about 10% to 1.10 (from 1.0 liters/sec), the resulting calibration would be fairly accurate.

The filter only needs to be replaced if the paper inside the filter tears. 2. Insert the Calibration Syringe/Filter Assembly into the airflow transducer. IMPORTANT! Always insert on the side labeled “Inlet.” Calibration Syringe into airflow transducer Insert syringe assembly so that the transducer cable exits on the left, as shown above. If using an older SS11L transducer with non-removable head, insert syringe assembly into the larger diameter port. IMPORTANT: If the lab sterilizes the airflow heads after each use, make sure a clean head is installed now. Never hold onto the airflow transducer handle when using the Calibration Syringe or the syringe tip may break. The Airflow Transducer is sensitive to gravity so it needs to be held upright throughout the calibration and recording.

This is not absolutely critical, but will increase the accuracy of Airflow to Volume calculations. f) The Subject must try to expand the thoracic cavity to its largest volume during maximal inspiratory efforts. (The Subject should wear loose clothing so clothing does not inhibit chest expansion.) g) During recording of FEV, the Subject should attempt to exhale as quickly as possible into the mouthpiece. h) During recording of MVV, the Subject should attempt to exhale and inhale as quickly and deeply as possible. Breathing rates should be faster than 60 breaths/minute or greater than 1 breath/second for the best results. The breathing needs to be maintained for 12-15 seconds.

The SS12LA variable range force transducer element is a cantilever beam load cell incorporating a thin-film strain gauge. Because the strain elements have been photolithographically etched directly on the strain beam, these transducers are rugged while maintaining low non-linearity and hysteresis. Drift with time and temperature is also minimized, because the strain elements track extremely well, due to the deposition method and the elements’ close physical proximity. The SS12LA also incorporates impact and drop shock protection to insure against rough laboratory handling. Forces are transmitted back to the beam via a lever arm to insure accurate force measurements. Changing the attachment point changes the full scale range of the force transducer from 50g to 1000g. The beam and lever arm are mounted in a sealed aluminum enclosure that includes a 3/8" diameter mounting rod for holding the transducer in a large variety of orientations. The SS12LA comes equipped with a 2-meter cable and plugs directly into the MP3X module. The SS12LA mounting rod can be screwed into the transducer body in three different locations, two on the top and one on the end surfaces of the transducer. The mounting rod can be placed in any angle relative to the transducer orientation. The SS12LA can be used in any axis and can be easily mounted in any standard measurement fixture, including pharmacological setups, muscle tissue baths and organ chambers. The SS12LA has 5 different attachment points that determine the effective range of the force transducer. These ranges are 50g, 100g, 200g, 500g and 1,000g. The point closest to the end is the 50g attachment point, while the point closest to the middle is the 1,000g attachment point. Two S-hooks are provided with the SS12LA; one has a .032" diameter wire and the other has a .051" diameter wire. The smaller hook is to be used for the 50g, 100g and 200g ranges. The larger hook is intended for the 500g and 1000g ranges. The larger hook is intentionally a tight fit to generate a downward pull vector. To further increase proper readings, keep the unit level and align anything that hangs off the hook straight beneath it rather than at a sideways angle.

For all other range settings, force measurements from 10% to 90% full scale are linear to ±1.0%. CALIBRATION The SS12LA is easily calibrated using weights of known mass. Ideally, calibration should be performed with weights that encompass the range of the forces expected during measurement and should cover at least 20% of the full scale range of the transducer. When calibrating for maximum range on the force transducer, use weights that correspond to 10% and 90% of the full scale range for best overall performance. FORCE TRANSDUCER CALIBRATION Calibrating a force transducer is a two step process. The first step involves finding the optimal Gain setting for the transducer and the second step is the actual calibration. 1) To find the optimal Gain setting: a) Start with the software Preset for the force range desired. To set the Presets: MP3X menu > Setup Channels > Analog Presets > “Force (range)” b) Load the transducer with the maximum expected weight. c) Collect data for a few seconds at these settings. d) Inspect the sample data; look for data that is “railed” or “clipped.” This occurs when the input signal (times the gain setting) is too large relative to the maximum input range. An example of clipped data follows. BIOPAC Hardware | SS12LA | Page 2 - 3 Updated: 3.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com Gain set too high — Clipped Force data e) If the signal is clipped, decrease the Gain setting by one step (e.g., from x5000 to x2500) and collect new data at the lower gain setting. To access the Gain setting: MP3X menu > Setup Channels > Force preset channel > View/Change Parameters icon > Gain pull-down menu f) Repeat this procedure until the signal no longer appears “clipped.” Once an optimal gain setting for the transducer has been established, this same gain setting can be used for other similar transducers and similar measurements. 2) The next step is to actually calibrate the transducer, which means mapping the input signal to more meaningful units (such as grams). To do this: a) Access the Channel scaling dialog box (MP3X menu > Setup Channels > Force preset channel > View/Change Parameters icon > Scaling button). Note: In this sample dialog, a weight of 5 grams was placed on the transducer and the Cal 1 button was pressed. The transducer weight was then removed and Cal 2 was pressed. b) Place the maximum expected weight or force on the transducer. c) Click on the Cal 1 button in the Channel scaling window. A voltage value will be automatically entered in the corresponding Input value box. d) Remove all weight or force from the transducer. e) Click on the Cal 2 button in the same scaling window. A voltage value will be automatically entered in the corresponding Input value box. The transducer will be calibrated to the set values the next time an acquisition is started.

Connect to the tubing via the standard rotating Luer-lok fittings. This assembly consists of a disposable transducer with a 30cm cable that attaches to a reusable 3-meter cable that is designed to interface with the MP3X. The transducer is supplied non-sterile but can be cold sterilized. Note: The SS13L Pressure transducer is not intended for use with humans. Typical software settings for the blood pressure transducer are described in the table below: Filter 1 Low pass 66.5 Hz Q = 0.5 Filter 2 Low pass 38.5 Hz Q = 1.0 Filter 3 Band Stop 60 Hz Q=5 Hardware filter 1 KHz Gain 100 (preset) Coupling DC These settings are automatically applied when the Pressure preset is selected, but settings can be adjusted if necessary. PRESSURE TRANSDUCER CALIBRATION Calibrating a blood pressure transducer is a two step process. The first step involves finding the optimal gain setting for the transducer and the second step is the actual calibration. 1) To find the optimal gain setting: a) Start with the software Presets (in this case, a gain of 100) To set the Presets: MP3X menu > Setup channels > Analog Presets > select “Pressure” b) Bring the transducer to the approximate maximum and minimum expected pressures. c) Collect data for a few seconds at these settings. d) Inspect the sample data; look for data that is “railed” or “clipped.” This occurs when the input signal (times the gain setting) is too large relative to the maximum input range. An example of clipped data is shown at right. e) If the signal is clipped, decrease the gain setting by one step (e.g., from x5000 to x2500) and collect new data at the lower gain setting. To access the Gain setting: MP3X menu > Setup channels > Pressure preset channel > Gain set too high — Clipped BP data View/Change Parameters icon > Gain pulldown menu f) Repeat this procedure until the signal no longer appears “clipped.” Once an optimal gain setting for the transducer has been established, this same gain setting can be used for other similar transducers and similar measurements. 2) The next step is to actually calibrate the transducer, which means mapping the input signal to more meaningful units (such as mmHg). To do this: a) Access the Channel scaling dialog box (MP3X menu > Setup Channels > Pressure Preset channel > View/Change Parameters icon > Scaling button).

The transducer can be used with the Noninvasive Blood Pressure Cuff or as a stand-alone device. If used with the cuff, Korotkoff sounds can be recorded for easy determination of systolic and diastolic blood pressure. When used on its own, it can record a variety of acoustical signals, including heart sounds and sounds associated with rubbing or grinding (e.g., Bruxism). The acoustical transducer element is a Piezo-electric ceramic disk that is bonded to the interior of a circular metallic housing. Grounding Note When using this transducer with the EBI100C module, do not connect the GROUND pin of the TSD108 to the DA100C module. Doing so will cause inaccurate impedance measures, because the TSD108 contact surface is tied to the isolated ground. An alternative is to insulate the TSD108 from the skin surface by using a latex balloon or some other nonconductive barrier. If the latter procedure is followed, the GROUND pin may be attached to the DA100 module. TSD108: Korotkoff signal is recorded by a DA100C amplifier set to AC, 5000 Hz LP and a gain of 50 to 200. SS17L: To record the Korotkoff signal, select SS17L preset from MP3x/MP4x > Set Up Channels menu. The signal for the physiological sounds transducer is usually further conditioned by the software. In a calculation channel, the signal can be bandpass filtered from 50 to 200 Hz. The sampling rate for the entire recording needs to be about 500 Hz, assuming the physiological sounds transducer is used.

This complete assembly is commonly referred to as a sphygmomanometer. Typically, the cuff is wrapped around the upper arm and is inflated to a pressure exceeding that of the brachial artery. This amount of pressure collapses the artery and stops the flow of blood to the arm. The pressure of the cuff is slowly reduced as the pressure transducer monitors the pressure in the cuff. As the pressure drops, it will eventually match the systolic (peak) arterial pressure. At this point, the blood is able to “squirt” through the brachial artery. This squirting results in turbulence that creates the Korotkoff sounds. The cuff pressure continues to drop, and the pressure eventually matches the diastolic pressure of the artery. At that point, the Korotkoff sounds stop completely, because the blood is now flowing unrestricted through the artery. SETUP The graph at right illustrates a typical recording using the TSD120/SS19L. TSD120: Pressure signal is recorded via a DA100C amplifier set to DC, 10Hz LP and a gain of 200. SS19L/LA: To record the pressure signal, Select SS19L/LA preset from the MP3x/MP4x > Set Up Channels menu. RECORDING As the cuff is wrapped around the upper arm of the subject, be sure to place the physiological sounds transducer underneath the blood pressure cuff, directly over the brachial artery. Transducer placement is very important to get the best possible recordings of Korotkoff sounds. Finish wrapping the cuff around the upper arm and secure it with the Velcro® seal. Now, start inflating the cuff with the pump bulb. The pressure trace shows the hand pump driving the cuff pressure up to about 150 mmHg. Then the cuff pressure is slowly released by adjusting the pump bulb deflation orifice. Notice that the Korotkoff sounds begin appearing when the cuff pressure drops to about 125 mmHg (bottom trace). As the pressure continues to drop, the Korotkoff sounds eventually disappear, at about 85 mmHg. The systolic pressure would be identified at 125 mmHg and the diastolic pressure would be 85 mmHg.

To calibrate the transducer, wrap the cuff into a roll and begin to inflate the cuff slowly with the pump bulb. The pressure change will be noticeable on the mechanical indicator. Set the cuff pressure to one lower pressure (typically 20 mmHg) and then one higher pressure (typically 100 mmHg). In this manner the pressure transducer can be calibrated using the standard procedure in the SCALING dialog (in AcqKnowledge). To use the cuff at a future date, simply save the calibration settings in a stored file. See also: DA100C Calibration options.

Goniometers transform angular position into a proportional electrical signal. Goniometers incorporate gauge elements that measure bending strain along or around a particular axis. BIOPAC goniometers are unobtrusive and lightweight, and can be attached to the body surface using double-sided surgical tape (and can be further secured with single sided tape). The goniometers have a telescopic endblock that compensates for changes in distance between the two mounting points as the limb moves. The gauge mechanism allows for accurate measurement of polycentric joints. All sensors connect directly to the BIOPAC Acquisition Unit as part of an MP or BSL System. Activity data can be displayed and recorded, leaving the subject to move freely in the normal environment. The bending strain is proportional to the sum total angular shift along the axis. Because the bending force is extremely small, the output signal is uniquely a proportional function of the angular shift. Twin-axis Goniometers Dual output devices that can measure angular rotation about two orthogonal planes simultaneously. Goniometers provide outputs to simultaneously measure around two orthogonally rotational axes (e.g. wrist flexion/extension and radial/ulnar deviations). —wrist or ankle use TSD130A/SS20L/SS20/BN-GON-110-XDCR —elbow, knee or shoulder use TSD130B/SS21L/SS21/BN-GON-150-XDCR Torsiometers Measure angular twisting (as on the torso, spine or neck) as opposed to bending.

Due to the wide range of applications, one method of attachment cannot be recommended. Experience has proven that standard medical adhesive tape is an excellent adhesion method in the majority of cases. Single-sided and double-sided medical tape (such as BIOPAC TAPE1 or TAPE2) should be used for the best results. 1. Attach pieces of double-sided tape to the underside of the goniometer endblocks. 2. Stick the tape to the subject and allow for the telescoping of the goniometer. The goniometer should be fully extended when the joint is fully flexed. 3. Press the two endblocks firmly onto the subject and ensure that the goniometer is lying over the top of the joint. When the joint is extended, the goniometer may present an “oxbow.” 4. For additional security, pass a single wrap of single-sided medical tape around each endblock. 5. Secure the cable and connector leaving the goniometer with tape to ensure that they do not pull and detach the goniometer. For accurate results from long recordings Employ double-sided adhesive between the endblocks and skin, and place single-sided adhesive tape over the top of the endblocks. No tape should come into contact with the spring. The connection lead should also be taped down near the goniometer. For applications where quick or rapid movements are involved Fit a “sock” bandage over the whole sensor and interconnect lead. This does not apply to the finger goniometer (TSD130E/SS24L/SS24/BN-GON-F-XDCR), which has a different working mechanism. When the goniometer is mounted across the joint, the center of rotation of the sensor measuring element may not coincide with the center of rotation of the joint (for example, when measuring flexion /extension of the wrist). As the joint moves through a determined angle, the relative linear distance between the two mounting positions will change. To compensate for this, all sensors are fitted with a telescopic endblock that permits changes in linear displacement between the two endblocks along axis ZZ without the measuring element becoming over-stretched or buckled. In the free or unstretched position, the distance between the two endblocks is L1. If a light force is applied, pushing the endblocks away from each other, this length will increase to a maximum of L2. When the light force is removed, the distance between the two endblocks will automatically return to L1. This creates several advantages: accuracy is improved; sensors can be worn comfortably and undetected under normal clothing; the tendency for the position of the sensors to move relative to the underlying skeletal structure is reduced. BIOPAC Hardware | Gonio-Torsio | Page 2 - 9 Updated: 11.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com If a light force is now applied, pushing the two endblocks linearly towards each other, the only way the distance L1 can decrease in length is if the measuring element buckles. Buckling is detrimental to the accuracy of the goniometer and torsiometer sensors, so attachment instructions are provided for the most commonly measured joints (on page 8), to ensure that it does not occur in practice. There is no universal rule governing which size of sensor is most suitable for a particular joint; this depends on the size of the subject. In general, the sensor must be capable of reaching across the joint so that the two endblocks can be mounted where the least movement occurs between the skin and the underlying skeletal structure. In certain circumstances, more than one size of sensor will be appropriate. WARNINGS 1. Take care to handle the goniometer and torsiometer sensors as instructed. Mishandling may result in inaccurate data, reduced equipment life, or even failure. 2. Observe the minimum bend radius value for each goniometer and torsiometer at all times, particularly when attaching and removing the sensors from the subject. Failure to do this will result in reduced equipment life or failure. 3. Never remove the goniometer from the subject by pulling on the measurement element and/or protective spring. Remove the endblocks individually and carefully, making sure not to exceed the minimum permissible bend radius, particularly where the measuring element enters the endblocks. 4. Take care when mounting goniometers to ensure that the measurement element always forms a “simple” bend shape. Accuracy will be reduced if an “oxbow” shape occurs in the element. 5. Do not bend the finger goniometer more than ±20° in the Y-Y Plane or reduced equipment life and/or failure may result. 6. Do not exceed rotations of ± 90° about ZZ. Exceeding the torsiometer range may result in a reduction of the life of the unit or failure. 7. Disconnect the transducers from the BIOPAC Acquisition Unit before cleaning or disinfecting goniometers and torsiometers. MAINTENANCE & SERVICE No periodic maintenance is required to ensure the correct functioning of the sensors. The sensors contain no user serviceable components. If the sensor fails, it should be returned to BIOPAC Systems, Inc. Please request a Return Merchandise Authorization (RMA) number before returning the sensor and include a description of what has been observed and what instrumentation was in use at the time of sensor failure in the return package. Calibration When using all goniometers and torsiometers, the minimum value of bend radius must be observed at all times, particularly when attaching and removing the sensors from the subject. Failure to do this will result in reduced unit life or failure. The sensors have been designed to be as light as possible and the operating force to be a minimum. This permits free movement of the joint without influence by the sensors. The sensors measure the angle subtended between the endblocks. Use the software calibration features (under Setup Channels) to calibrate any of the BIOPAC series goniometers. Each goniometer requires a DA100C amplifier, BN-GONIO or MP3X/45 analog input per rotational axis. Accordingly, the twin axis goniometers will need two DA100C amplifiers, one BN-GONIO or two MP3X/45 analog channels to simultaneously measure both rotational axes. The recommended excitation voltage is +5 VDC. 1. Place goniometer with care to verify that limb/joint/torso attachment will not result in over stretch at the limits of limb/joint/torso movement. 2. Put body in the first position, which brackets one end of range of movement. Press CAL 1. 3. Put body in the second position, which brackets The other end of range of movement. Press CAL 2.

For example, placing a sensor on an adult elbow and moving from the neutral position to maximum flexion and back to the neutral position, the unit will function for a minimum of 600,000 cycles. BIOPAC Hardware | Gonio-Torsio | Page 4 - 9 Updated: 11.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com OVERVIEW OF THE BIOPAC GONIOMETER SERIES As with all measuring equipment, to correctly interpret the data, understanding the working principles (i.e., what the sensor measures) before use is helpful. BIOPAC Systems, Inc. manufactures three types of sensors: 1. The single axis finger goniometer permits the measurement of angles in one plane. Angles are measured when rotating one endblock relative to the other about axis X-X. The goniometer is not designed to measure rotations about Y-Y. Any attempt to bend the unit in this way more than ± 20 from the neutral position will result in a reduction of the life of the unit or failure. The goniometer does not measure rotations about axis Z-Z, though this movement is permitted without reduced life or damage occurring. This goniometer is designed primarily for the measurement of finger and toe flexion/extension. 2. The twin axis goniometers permit the simultaneous measurement of angles in two planes, e.g. wrist flexion / extension and radial / ulnar deviation. Rotation of one endblock relative to the other about axis X-X is measured using the gray plug. Similarly, rotation of one endblock relative to the other about axis Y-Y is measured using the blue marked plug. Assuming the goniometer is mounted correctly (as outlined here), the outputs of the two channels are independent of linear displacements along axis Z-Z. It should be noted that rotation of one endblock relative to the other around axis Z-Z cannot be measured. These goniometers function in the same way, and differ only in size. BIOPAC Hardware | Gonio-Torsio | Page 5 - 9 Updated: 11.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com 3. The single axis torsiometers permit the measurement of rotation in one plane, e.g. forearm pronation/supination. Axial rotation of one endblock relative to the other along axis Z-Z is measured from the gray plug. If the torsiometer is bent in planes X-X or Y-Y, the output remains constant. All torsiometers function in the same way, and difference only in size. WARNING! Torsiometers measure rotations about ZZ in the range ± 90°. Exceeding the range may result in a reduction of the life of the unit or failure. The working mechanism is the same for all three types of sensors. There is a composite wire between the two endblocks that has a series of strain inside the protective spring gauges mounted around the circumference. As the angle between the two ends changes, the change in strain along the length of the wire is measured and this is equated to an angle. The design is such that only angular displacements are measured. If the two ends move linearly relative to each other, within the limits of telescopic endblock, without changing the relative angles between them, then the outputs remain constant. The amount of strain induced in the gauges is inversely proportional to the bend radius that the beam is bent around. If the stated minimum permissible bend radius is exceeded then unit life will be reduced or, in severe cases, failure may result.

The following figures show sign conventions for the most common joints. BIOPAC Hardware | Gonio-Torsio | Page 7 - 9 Updated: 11.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com WRIST – Goniometer TSD130A/SS20L/SS20/BN-GON-110-XDCR Attach the telescopic endblock to the back of the hand, with the center axis of the hand and endblock coincident (top of figure — viewed in the frontal plane). While fully flexing the wrist (middle and bottom of figure), extend the goniometer to Position 2 (as shown on page 2) and attach the fixed endblock to the forearm so that when viewed from the dorsal plane, the axes of the forearm and endblock are coincident. The wrist may now be flexed or extended, abducted or adducted, with the goniometer freely sliding between Positions 1 and 2. Measurement of flexion/extension is obtained from the gray plug, and abduction/adduction is obtained from the blue plug. ARTICULAR COMPLEX OF THE FOOT – Goniometer TSD130A/SS20L/SS20/BN-GON-110-XDCR Attach the telescopic endblock to the back of the heel. Extend the ankle to the maximum extension anticipated during measurement, and attach the fixed endblock to the posterior of the leg, with the goniometer in Position 1 (maximum length, as shown on page 2) so that the axes of the leg endblock are coincident. Flexion/extension of the ankle may now be monitored using the gray plug and pronation/supination using the blue marked plug. ELBOW – Goniometer TSD130B/SS21L/SS21/BN-GON-150-XDCR Attach the telescopic endblock to the forearm with the center axis of the endblock coincident with the center axis of the forearm. With the elbow fully extended, move the goniometer to Position 2 (maximum length, as shown on page 2) and attach the fixed endblocks to the upper arm, with the center of the endblock and the center axis of the upper arm coincident. Now the elbow may be fully extended with the telescopic endblock freely sliding between Positions 1 and 2. Measurement of flexion/extension is obtained from the blue marked plug, and the gray plug is redundant. Note that the telescopic endblock is mounted on the half of the forearm nearest to the elbow joint. Movements of pronation and supination may be made and will affect the measurement of flexion/extension by a small amount. HIP – Goniometer TSD130B/SS21L/SS21//BN-GON-150-XDCR Attach the fixed endblock to the side of the trunk in the pelvic region. With the limb in the position of reference, extend the goniometer to Position 2 (maximum length, as shown on page 2) and attach the telescopic endblock to the thigh, so that axes of the thigh and endblock coincide (when viewed in the sagittal plane, as shown). The thigh may now be flexed or extended, abducted or adducted, with the goniometer sliding freely between Positions 1 and 2. Measurements of flexion/extension are obtained from the blue marked, and abduction/adduction from the gray plug. BIOPAC Hardware | Gonio-Torsio | Page 8 - 9 Updated: 11.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com KNEE – Goniometer TSD130B/SS21L/SS21/BN-GON-150-XDCR Mount the telescopic endblock laterally on the leg so the axes of the leg and endblock coincide, when viewed in the sagittal plane. With the leg fully extended in the position of reference, extend the goniometer to Position 2 (maximum length, as shown on page 2) and attach the fixed endblock to the thigh so the axes of the thigh and endblock coincide. The knee may now be flexed or extended with the goniometer freely sliding between Positions 1 and 2. Measurements of flexion/extension may be monitored using the blue marked plug and varus/valgus may be monitored using the gray plug. FOREARM PRONATION /SUPINATION – Torsiometer TSD130C/SS22L/SS22/BN-TOR-110-XDCR or TSD130D/SS23L/SS23/BN-TOR-150-XDCR Attach the two endblocks of the torsiometer to the forearm, with the slider mechanism approximately midway between the two extremes. Measurements of pronation/supination may now be made from the gray plug. Movements of wrist flexion/extension or radial/ulnar deviation will not affect the output. FINGERS AND TOES –Goniometer TSD130E/SS24L/SS24/BNGON-F-XDCR The single axis goniometer is intended for use on fingers and toes. Angles are measured by rotating one endblock relative to the other about axis XX (as shown on page 2). The goniometer is not designed to measure rotations about Y-Y. Any attempt to bend the unit in this way more than +/-20° from the neutral position will result in reduced unit life or failure. The goniometer does not measure rotations about the axis Z-Z. The unit is designed to fit over the joint to be measured and has extremely high flexibility to ensure the instrument does not interfere with normal joint movement. One endblock is attached either side of the joint. Unlike other BIOPAC Goniometers and Torisometers, and “Z” series sensors, an “oxbow” shape is permitted in the measuring element. This is not detrimental to the results and does not reduce life of sensor. Care should be taken, however, that the minimum bend radius is not exceeded. BIOPAC Hardware | Gonio-Torsio | Page 9 - 9 Updated: 11.21.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com SS25LA HAND DYNAMOMETER Use the hand dynamometer to measure grip force—use in isolation or combine with EMG recordings for in-depth studies of muscular activity. The lightweight, ergonomically designed transducer provides direct readings in kilograms or pounds. The simple calibration procedure makes this device easy to use for precise force measurements, and the isometric design improves experiment repeatability and accuracy. The SS25LA is a basic unit, designed for student lessons; it can also be used in the MRI, with proper module setup, since it employs plastics in the spring constant. The highest performance dynamometer is TSD121C, which employs a four terminal, laser-trimmed, wheatstone bridge built onto metal elements. Hardware Setup Connect the SS25LA Simple Sensor to a CH input on the front panel of an MP3X unit. Proper grip: Place the palm across the shorter bar and wrap fingers to center the force. Scaling — Software Setup for the MP3X 1) Select Set Up Channels under the MP3X menu and enable one analog channel. 2) Select the desired Clench Force Preset (kg or lbs, the example to the right is shown in units of kg.) 3) Click on the Setup button. 4) Click on the Scaling button to activate a dialog box similar to the one shown at right. 5) In the Map value column, note the default scaling of “0” for Cal2 and “100” for Cal1. These represent 0 and 100 kilograms, respectively. 6) Place the SS25LA on a flat surface. 7) Click the Cal2 button to obtain an initial calibration reading. A value similar to the above example “0.7556” will appear. 8) To obtain the Cal1 input value, add the Cal2 input value to the default Cal1 3.5 mV per 100 kg value. (In this example, this value would be 0.7556 mV + 3.5 mV = 4.2556 mV.) NOTE: The above instructions are for BSL 4 and higher. In BSL 3.7.7 and earlier, placement of the CAL1 and CAL2 scale values are reversed. Calibration Confirmation a) Click “Start” to begin data acquisition. b) Place the SS25LA on a flat surface and then place a known weight on the uppermost portion of the grip. c) Review the data to confirm that the known weight is reflected accurately in the data (sample at right). d) Adjust the Scaling parameters and repeat steps a-c as necessary.

If contention exists, the channel data will be corrupted. See also: Setup notes for external devices and channel contention issues. Software Setup SS26LB/SS27L: a) Select MP3X > Set Up Channels > Setup and enable three analog channels, one for each axis b) For each channel, select the appropriate Accelerometer Preset (5g or 50g) from the Preset list. c) Click on Setup and then click on Scaling: d) In the Scale value fields, enter the scaling factors required, 1 for Cal1 and –1 for Cal2. e) Enter “g” for the Units label, as shown. (This unit should appear by default in Accelerometer presets.) f) Take the accelerometer and rest it in the upright position on the tabletop. g) Calibrate the device by rotating it through 180° and taking a calibration reading at each point. h) To calibrate the Y-axis, start with the transducer sitting on the table, face up, and click CAL1. Rotate the transducer 180°, so that it is now sitting upside down, and click the CAL2 button. This procedure must be followed for each axis. A label on the front of the transducer displays the X- and Y-axes. The Z-axis rotates from the end with the label and the end with the cable. TSD109 Series: a) Select MP150 > Set Up Channels > Add New Module. b) Choose HLT100C-A1 from the module type list and click “Add”. c) Choose TSD109C (5g) or TSD109F (50g) from the transducer list and click “OK”. d) Follow the onscreen calibration dialogs. e) Repeat steps a-d for channels A2 (Y-Axis) and A3 (Z-axis). Testing Calibration To see if the calibration is correct: a) Start acquiring data (for the test procedure, a sample rate of 50 samples per second should be used) b) Rotate the accelerometer 180° through each axis. c) Set the vertical scale to 1 and the midpoint to 0 for all channels. d) Repeat the calibration procedure (by rotating the transducer 180°) through each axis. e) Visually confirm the correct calibration. The screen shot above shows a tri-axial accelerometer being rotated through each axis. Channel 1 (X-axis) shows the signal moving from 1g to -1g as the transducer is rotated. Likewise, Channel 2 (Y-axis) shows the same phenomenon as previously described. Finally, Channel 3 (Z-axis) has also been tested and the calibration confirmed.

The transmitter can be attached to any part of the subject's body to measure three-axis acceleration associated with movement in that particular location. The system comes factory preset to support an operational range of ±16 G, with a maximum system bandwidth of 400 Hz. Ranges can be set to as low as ±2 G with bandwidths as low as 3 Hz. The system can also be configured to act as a "tap detector," detect either single or double taps. In this mode, the system can act as an event recorder for self-report. When "double-tapped," for example, the system will output a pulse to precisely mark the time location of the observed event. In Acceleration measurement mode, the BN-ACCL3 will output X, Y and Z acceleration values on three associated channels. The system is very well suited for mobile applications. The system can measure the acceleration of gravity (static) for tiltsensing and can also measure very fast-changing, dynamic acceleration resulting from rapid movement or impact.

The SS31L incorporates a precision high-frequency current source, which injects a very small (400µA rms) current through the measurement tissue volume defined by the placement of a set of current source electrodes. A separate set of monitoring electrodes then measures the voltage developed across the tissue volume. Because the current is constant, the voltage measured is proportional to the characteristics of the biological impedance of the tissue volume. Use the SS31L to measure changes in Cardiac Output under a variety of conditions: laying down, sitting up, standing up, and post-exercise. Use on stationary subjects; the SS31L is sensitive to motion artifact. See BSL PRO Lesson H21 Impedance Cardiography for sample SS31L setup and data.

It uses a Taylor Hammer—the most common type of reflex hammer used by doctors and nurses—and incorporates electronics to record the time and the relative strength of the impact. Being able to measure the strength of impact allows students to take threshold measurements; that is, they can measure how much of an impact is needed to elicit a response. The hammer only sends a response when contact is made with the subject. See Lessons L20, H16, H28.

The transducers plug directly into the MP3X generalpurpose differential amplifier. The differential pressure ports are located on the front of the transducers and are easily connected to breathing circuits, pneumotachs or plethysmograph boxes. These transducers are very useful for interfacing a variety of small animal pneumotachs or plethysmographs to the MP System. The transducers are extremely sensitive and come in three ranges to suit a number of different applications. RX137 flow heads connect to the SS41L differential pressure transducer via standard 4mm ID tubing. Included with each SS45L-SS52L.

These pneumotach transducers consist of a low flow, pneumotach airflow head (RX137B through RX137H and SS46L through SS52L) coupled to a precision, highly sensitive, differential pressure transducer (TSD160A or SS40L). RX137 Series The pneumotachs will connect directly to a breathing circuit or plethysmogram chamber. For airflow and lung volume measurements, connect a short airflow cannula to the RX137 series flow head. All pneumotachs are equipped with an internal heating element and AC137A 6-volt power supply. TSD160 RX137A MRI Usage (TSD137): MR Conditional Condition: Tested to 3T: Contains ferrous material – must be clamped down in the safe MRI operating area. See also: DA100C Calibration options. RX137 SERIES REPLACEMENT AIRFLOW HEADS (SHOWN ABOVE) For TSD137 & SS46L-SS52L Series Pneumotachs The RX137 series are airflow heads for the TSD137 and SS46L-52L series pneumotach transducers. The RX137 heads can be mixed and matched with any of the TSD137 and SS46L-SS52L series pneumotachs. Switching one head for another when using a single pneumotach can accommodate a wide range in flows. RX137 heads connect to the TSD160A or SS40L differential pressure transducer via standard 3mm or 4mm ID tubing. Multiple RX137 heads help eliminate equipment downtime during cleaning procedures. PNEUMOTACH AIRFLOW TRANSDUCER CALIBRATION Connect tubing between the calibration syringe and the transducer, then follow the procedure for TSD117/SS11LA but move the calibration syringe plunger at a reduced velocity due to the very high sensitivity to flow of the TSD137/SS46L-SS52L series. Each of the TSD137/SS46L-SS52L series is factory calibrated to a known flow level, as indicated on the transducer. FLOW HEAD CLEANING & DISINFECTION IMPORTANT: RX137 series airflow heads are manufactured with a very thin layer of synthetic resin, so they should never be cleaned with an organic solvent. We recommend cleaners such as Hydro-Merfen at the concentration used for medical material, or Gluterex. Before using the airflow head, be sure it is dry. Never heat the airflow head higher than 50 C. 1. Submerge the airflow head in a disinfectant solution for approximately one hour. 2. Rinse the airflow head with distilled or de-mineralized water. 3. Use compressed air or another compressed gas [pressure up to 5kg / cm2 (5 bar)] to drive any remaining water out of the airflow head. 4. Allow the airflow head to dry completely in ambient air (or continue using compressed air if time requires it).

This can be prevented by fitting a non-return valve and measuring only inspiration or alternatively by heating the flowhead, but viscosity errors may arise (from which in the first few breaths especially) preheat the inspired air most uncomfortably. In this range of flow heads, the problem is approached from a fresh angle. By mounting fine stainless steel gauze in plastic rings, thermal inertia is greatly reduced. The gauze therefore rapidly equilibrates in temperature with passing air and condensation is minimal.

The probe must stay connected to the interface at all times to keep it warmed up. If the probe is disconnected for more than a few minutes, the warm-up routine will need to be repeated. BIOPAC Hardware | SS69L | Page 1 - 4 Updated: 3.28.2013 HARDWARE GUIDE 3. info@biopac.com support@biopac.com www.biopac.com Calibration — optional Calibration is optional. To measure relative change, probe calibration is not essential. To improve accuracy for discrete measurements, probe calibration is recommended. a. Zero-Oxygen (CAL 1) i) Launch the BIOPAC software and generate the scaling dialog for the probe channel. (Select MP menu > Set Up Channels > View/Change Parameters > Scaling Button.) ii) Enter 0 for CAL 1 Scale value. iii) Remove the probe from the water and place the tip of the probe into the Sodium Sulfite calibration solution. IMPORTANT: No air bubbles can be trapped below the tip of the probe or the calibration will be distorted. If the voltage does not rapidly decrease, tap the side of the bottle with the probe to dislodge any bubbles. iv) When the voltage stabilizes (~1 minute), press the CAL 1 button. The Input value result should be in the 0.2 - 0.5 mV range. b. Saturated Dissolved O2 (CAL 2) i) Rinse the probe with distilled water and gently blot dry. ii) Unscrew the lid of the calibration bottle and slide the grommet approx. 12 mm (1/2”) onto the probe body. iii) Add water to the bottle to the depth of about 6 mm (1/4”) and screw the bottle into the cap. IMPORTANT: Do not touch the membrane or get it wet during this step. iv) Keep the probe in the position for about one minute and then press the CAL 2 button.

Place the tip of the probe into the sample to be measured. Submerge the tip about 4-6 cm (2”). d. Gently stir the probe in the sample. IMPORTANT: Keep stirring the probe in the sample—water must always be flowing past the probe tip for accurate measurements. As the probe measures the concentration of dissolved oxygen, it removes oxygen from the water at the junction of the probe membrane. If the probe is left still in calm water, reported dissolved O2 measurements will appear to be dropping. Storage < 24 hours: Store the probe with the membrane end submerged in about 3 cm (1”) cm of distilled water > 24 hours: Remove the membrane cap, rinse the inside and outside of the cap with distilled water, and then shake the membrane cap dry. Rinse the exposed anode and cathode inner elements, and then blot dry with a lab wipe. Reinstall the membrane cap loosely onto the electrode body for storage—do not tighten. Polishing The anode or cathode inner elements become discolored or appear corroded, use the polishing strips provided (once a year is generally sufficient). Contact BIOPAC for polishing details if necessary.

The CBL204 plugs into any 100C-series biopotential amplifier Touchproof “Y” input or STMISO series output and provides two sockets to connect to adapter electrode leads terminating in Touchproof sockets. Plug multiple CBL204s together to reference 3 or more electrode leads to the same input or output. For MP36/35/45 Systems, use to connect a glass microelectrode to multiple electrode sites (such as Vin- and GND from BSLCBL8/9 HighImpedance Cables). 1.5 mm ACCoupled USE CBL205 when more than one CBL205 electrode lead ground is required while recording adapter electrodermal activity (e.g., galvanic skin response). One end of the adapter plugs into the ground on the amplifier and the other end accepts the electrode lead. To record GSR with other biopotential signals (ECG, EEG, EOG, EGG, EMG, ERS), BIOPAC recommends using CBL205 connected to one ground on any of the biopotential amplifiers. The subject will be grounded through the Vin- of the GSR electrodes, but in some cases it is necessary to have more than one ground; in such cases, use CBL205 to prevent ground loops. CBL204 CBL205 Converts a 2 mm pin electrode or transducer lead to a Touchproof socket (1.5 mm ID), for connection to any of the 100C-series Biopotential or Transducer amplifiers or STMISO series modules. One CBL200 is required for each Touchproof socket. Converts a Touchproof (1.5 mm ID) socket electrode or transducer lead to an old-style 2mm pin, for connection to any of the 100B-series Biopotential or Transducer amplifier modules. Also used to connect a ground electrode lead (e.g. LEAD110A) to the UIM100C module (required when using the TSD150 active electrodes). One CBL201 is required for each Touchproof socket. For MP36/35/45 Systems CBL201 is used to update older model SS1L Shielded Lead Adapters. Adapts transducers with a 6.3 mm (¼) mono phone plug to the DA100C. For example, if—while recording a biopotential and GSR— the GSR electrode is removed during a stage of the experiment, to maintain a ground for the biopotential and avoid ground loops: 1. Connect the Vin- lead of the GSR as ground. 2. Connect an AC-coupled ground to the biopotential amplifier.

BIOPAC HSTM Series Probes must be used when stimulating humans. HSTM probes have current-limiting features, enhanced isolation and a user-operated “dead man” switch for optimum safety WARNING! Even with the HSTM probe, users must never create an electrical path across the heart (i.e. touching an active tip in each hand while the switch is engaged) and it should never be used on subjects with pacemakers. The HSTM01 handheld human-safe stimulating probe provides a superior degree of safety and comfort when using the Biopac Student Lab Stimulator for human stimulation. The ergonomic design allows the subject to focus on electrode placement instead of worrying about holding the electrode. The subject controls the stimulus presentation by activating the red safety switch. To stop the stimulus at any time, the subject simply removes his/her thumb from the switch and the electrode shuts off. The electrode is terminated in a BNC connector that interfaces with the BSLSTMA.

BIOPAC Hardware | EL250 SERIES | Page 1 - 2 Updated: 11.4.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com All EL250 Series electrodes require adhesive disks (ADD200 series) and recording gel (GEL1 or the preferred recording gel). See the Electrode Accessories section for further description. Instructions for EL250 Series Electrodes 1) Store electrodes in clean, dry area. 2) After use, clean electrode with cold to tepid water a) DO NOT use hot water. b) Cotton swabs are suggested. 3) The electrodes should be completely dry before returning to storage. 4) DO NOT allow the electrodes to come in contact with each other during storage (adverse reaction could take place). Electrodes may form a brown coating if they have not been used regularly. This should be removed by gently polishing the surface of the electrode element with non-metallic material. Wiping with mild ammonium hydroxide will also remove this coating. Rinse with water and store the electrode in a clean, dry container. 5) Remove an appropriate size electrode washer (ADD204, ADD208, or ADD212) from its waxed paper strip and carefully apply the washer to the electrode so the center hole of the washer is directly over the electrode cavity. 6) Fill the cavity with electrode gel (GEL100). No air bubbles should be present in the cavity. 7) Remove the white backing from the washer to expose the second adhesive side. 8) Place electrode on prepared skin area and smooth the washer into place. 9) Apply a few drops of electrode gel to fingertip and rub the exposed side of the adhesive washer (around the electrode) to rid its surface of adhesive quality.

Do not leave GEL in the cavity after use. If GEL is left in cavity, the Ag-AgCl electrode disk could degrade quickly with time because the electrode surface is somewhat porous to promote good conductivity to the GEL. 2. To clean the reusable electrode, use a cotton swab or toothbrush with tap water. 3. Use any lab cleaner with pumice (such as Ajax) with cotton swab or toothbrush to remove any dark residue from electrode surface. 4. Use Hydrogen Peroxide solution (2-3%) to brighten electrode surface (optional) or to sterilize electrode. Do not place the electrode in solution, but simply clean the electrode surface using a cotton swab. 5. Dry electrode off completely before storage.

Single-stage pressure regulators reduce the cylinder pressure to the delivery or outlet pressure in one step, and are generally good for short duration applications. This regulator is used to inject calibration gases into the GASSYS2 or AFT15 chambers to create the secondary calibration points for a proper gas calibration of O2 and CO2 sensors. The initial case (for the primary calibration points) is the chamber flooded with ambient air (20.95% Oxygen, 0.04% Carbon Dioxide and balance Nitrogen). The secondary case (for the secondary calibration points) is using the GASCAL with GASREG to inject a calibrated gas mixture into the chamber. The chamber will be flooded with this mixture from GASCAL. GASCAL is a tank containing 4% carbon dioxide, 16% oxygen and balance (80%) nitrogen. Use 3.2 mm ID tubing to run from GASREG output to the chamber and seal the 3.2 mm ID tube to the input port of the chamber, during calibration. Wait for the chamber to be flooded, typically about 1-2 minutes. Put regulator at 10 psi and open up the flow valve. After flooding, then largely close the flow valve, but keep some small flow during the calibration of secondary point, to maintain positive pressure in the chamber. The chamber needs to be flooded prior to attempting to calibrate for secondary points. After secondary calibration, shut down the tank by closing the main valve. GASCAL Cylinder Recycling Program available. Call 1-800-457-0809 to receive instructions for returning a cylinder; delivery paid by sender and recycling covered by manufacturer.

Modular assembly makes complete cleaning easy! GASSYS2 modules measure expired O2 and CO2 concentrations. When the subject inspires, air is drawn into the GASSYS2 through an airflow transducer. The SS11 (GASSYS2 EA/EB) or TSD107B (GASSYS2 RA/RB) airflow transducer is placed on the inspiration side to eliminate any effects associated with expired air humidity. When the subject expires, air is directed to the GASSYS2 module. The GASSYS2 is designed to work with saturated expired air. Obtain real-time Oxygen Consumption (VO2) and Respiratory Exchange Ratio (RER) measurements using the MP System with a GASSYS2 module and some airflow accessories. The GASSYS2 connects directly to the MP36 System (GASSYS EA/EB) or via the UIM100C (GASSYS RA/RB) and requires two channels. The non-rebreathing T-valve directs only expired air to the GASSYS2. Because only expired air is directed to the module, the system acts to average respiratory outflows. This averaging effect causes the CO2 and O2 concentrations to vary in accordance to the mean values resident in a few expired breaths. Two chamber sizes are available for the GASSYS2. Each chamber assembly includes the chamber casing and rod. The chambers work exactly the same way and are interchangeable on the module base. Use the smaller chamber size for small children/medium sized animals. 5-liter chamber — included in the GASSYS2-EA/RA; order chamber only as RX-GASA 1.7-liter chamber — included in the GASSYS2-EB/RB; order chamber only as RX-GASB The GASSYS2 also includes AFT7 tubing, AFT11E Coupler, AFT22 Non-rebreathing T-Valve, and a power supply. GASSYS2 Specs O2 sensor: Warm-up: 10 minutes. Response time 10-90%: 30 sec. Accuracy: ±1% FSR*. Zirconia solid electrolyte with a 0.1-25% sensing range. It runs hot, which helps burn off humidity. *FSR = Full Scale Reading Expected O2 sensor lifespan (in years): [5,256/(number of hours used per year)]*5 CO2 sensor: Warm-up: 2 minutes. Response time: < 120 seconds for a 90% step change. Uses a humidityrepellant (hydrophobic) membrane and has a sensing range of 0-5%. It uses non-dispersive infrared diffusion with single-beam IR and a self-calibrating algorithm. It also runs hot, which burns off humidity. Calibration: GASSYS2 sensors are factory calibrated prior to shipping. Power Supply: 12 V DC @ 1 amp (AC300A) wall adapter for serial numbers ending 200 or older. If used for 10 hours per week or 520 total hours in a year, O2 sensor lifespan would be [5,256/520]* 5 = 50.5 years BIOPAC Hardware | GASSYS2 | Page 1 - 4 Updated: 8.7.2013 HARDWARE GUIDE Dimensions/Weight 1.7-liter chamber 5-liter chamber Length: 22 cm 55 cm Height: 18 cm 18 cm Width: 14 cm 14 cm Weight: 1.38 kg 1.96 kg info@biopac.com support@biopac.com www.biopac.com GASSYS2 Software Scaling Defaults AcqKnowledge Software Default %O2 Scaling Default %CO2 Scaling BSL PRO Software Default %O2 Scaling Default %CO2 Scaling Calibration Procedure The GASSYS2 scaling parameters are factory-set to a “ballpark” default, but in order to achieve accurate measurements, these values must be re-calibrated in the AcqKnowledge or BSL PRO software using the following steps. 1. Flood the mixing chamber with fresh (ambient) air. (20.93% O2, 0.04% CO2) This can be accomplished by attaching the calibration syringe to the mouthpiece and cycling fresh air into the mixing chamber. 2. Monitor the gas concentration levels using AcqKnowledge or BSL PRO software. When the levels appear stabilized at ambient, obtain the first calibration point. (CAL 1) 3. Flood the chamber with the gas mixture using BIOPAC’s GASCAL and GASREG. The recommended concentration is 16% O2, 4% CO2 and 80% nitrogen (N2). 4. When the levels appear stabilized, obtain the second calibration point.

The two sensors, a screen and a copper-colored gas detector, are highly sensitive. 1) Unscrew the top knob attachment. 2) Remove the plastic lid from the flow chamber. 3) Gently pull the clear cylinder off the sensor base. 4) Detach the metal standing rod and its lower base attachment by holding the third of the standing rod nearest the base of the module and unscrewing the rod in a counter-clockwise motion. a. Depress the rod by applying pressure at the base – this unlocks the rod’s position and allows movement. b. Unscrew the rod in a counter-clockwise motion. BIOPAC Hardware | GASSYS2 | Page 3 - 4 Updated: 8.7.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com 5) Remove the chamber stand (gently pull back the chamber stand from the electronics base). 6) Clean the flow chamber with one of two methods: a. Use a soft cloth and Cidex Plus Sterilizing and Disinfecting Solution cleanser. Spray a light mist of Cidex cleanser on the parts of the device to be cleaned, and wipe the pieces with a dry rag. It is important never to get Cidex near the sensors of the device. Other cleansers should not be substituted for Cidex – non-Cidex cleansers might damage or abrade the flow chamber pieces. b. Heating the components in an autoclave sterilizing oven. 7) After cleaning reattach the platformed-standing rod to the electronics base. a. Align the exhaust tube at the bottom of the rod stand with the exhaust port on the electronics base and insert securely. b. Gently ease the rod stand back into its appropriate position on the electronics base. The sensors are very delicate—slowly lower the plastic base of the standing rod to the electronics base to make sure that the openings in the standing rod base correspond with the appropriate sensors. 8) Locate the latch opening for the security screw and align it with the screw, and then press the base of the standing rod to the sensor base. a. Revolve the rod until the lower screw drops into its opening. When the screw meets its opening, it should drop into the hole. b. Depress the rod by applying pressure on the lower third of the piece and rotate it in a clockwise motion until it locks into position. 9) Ease the clear cylinder back onto the device and lay its lower edge in the track on the electronics base. 10) Re-attach the plastic top to the clear cylinder. 11) Lock the plastic top into place by screwing in the security knob.

TURN OFF - Before turning off the unit, be sure that the current measurement was saved. - Power off the unit by switching the power button on the back TROUBLESHOOTING Tail Pulse signals are not regular. The animal may be under stress, resulting in excessive tail movement. Remove the animal from the RESTRAINER holder until it calms down before continuing with the experiment. The tail may not be sufficiently warmed or cooled down. Put the animal in the Tail Heater Chamber and repeat the heating process. Make sure the tail temperature is 32 C. Tail Cuff sizing may be incorrect. Check Table 5 on the following page for sizing descriptions. Tail Cuff Sensor position may be incorrect. Try re-attaching the sensor in a different location on the tail. The optimal location is between the mid-point of tail and base of tail (spinal column). Compressor is working continuously. Immediately turn off the NIBP system. Remove the Tubing from the Cuff connector on the panel of NIBP system Turn the system back on. Close the air outlet by pressing the finger on the Cuff output and press the “Start” button. The compressor will work for a few seconds and stop (please inform BIOPAC if the Compressor does not stop). The pressure chart should be viewable on the screen. If the Compressor stops automatically, it means that the system is working normally. There is leakage in the tubing connections and Cuff of the IRSENSOR. Make sure the tubing is securely attached.

Optionally, for additional lead length, use one MEC110C extension cable. 1. Plug the three JUMP100s into the desired points of the Nerve Chamber. 2. Connect the free ends of the JUMP100s to the mating ends of the CBL200s. 3. Then connect the free ends of the CBL200s to the Biopotential amplifier inputs. For additional lead length, plug the MEC110C into the Biopotential amplifier and plug the free ends of the CBL200s into the free end of the MEC110C. To connect the Nerve Chamber to the STM100C Stimulator, use one CBL106 and one CBL102. 1. Plug the red and black leads (2mm pins) of the CBL106 into the desired points of the Nerve Chamber. 2. Connect the free end (Female BNC) of the CBL106 to the mating end (Male BNC) of the CBL102. 3. Then insert the free end of the CBL102 (3.5mm phone plug) into the 50 Ohm output of the STM100C. Note: If the STM100C Stimulator is used with a Biopotential amplifier on the same nerve—which is nearly always the case—make sure that the black lead of the CBL106 (stimulation negative) is connected to the same pin as the ground lead going to the Biopotential amplifier. This is easy to do because the design of the JUMP100 allows stacking connections.

The tubephone design consists of a monaural acoustic transducer attached to a short, flexible, plastic tube, which fits into the subject’s ear with the aid of a foam tip. Use of the tubephone reduces ambient noise and bone conduction problems, which can interfere with auditory response recordings. Furthermore, because the Tubephone provides a 1 msec acoustic signal delay (due to plastic tube), it automatically separates true response from electromagnetic artifact resulting from speaker activation.

The sensitivity is 50 mV/Pascal (-46 dB re: 1 V/uBar): 0 dB SPL = 0 dBuV. Place the Probe Microphone insert tube in the auditory canal prior to the insertion of the OUT101 foam tip. The OUT101 Tubephone sound delivery tube and the Probe Microphone sound input tube will then be exposed to the same auditory chamber. Accordingly, the SPL is recorded, via the Probe Microphone, simultaneously with applied auditory stimulus from the OUT101 Tubephone. OUT102 PIEZO AUDIO TRANSDUCER The OUT102 piezo transducer is typically connected directly to the STM100C stimulator module. When the stimulator module output rises above 1.5 volts, the piezo indicator will emit a constant audible signal (3.0 kHz @ 80 dB). Accordingly, the device is very useful for providing an audible stimulus, or alarm, when a physiological signal passes a certain threshold. As such, the OUT102 makes an excellent audible BPM indicator for ECG, blood pressure or respiration signals. The device can also be used to indicate when temperature or other slowly moving variable (e.g. electrodermal response) passes a certain threshold. The threshold for the OUT102 is determined by adjusting the amplitude control on the STM100C module. The specific Biopotential or Transducer amplifier signal monitored can be recorded while simultaneously directed through the STM100C module. The OUT102 also connects directly to the UIM100C digital I/O ports for operation with Control Channel outputs. The OUT102 measures 2.5cm (dia) x 1cm (high) and comes equipped with a 1.8m cable terminated in a 3.5mm phone plug. An adapter is included for connecting the OUT102 to the UIM100C digital I/O ports.

A universal input voltage 3 amp battery charger is also included. The battery pack is lightweight and comes with a supplied carrying case with integral shoulder strap. The carrying case holds battery pack, charger and all associated cords. The BAT100A chemistry is Lithium Iron Phosphate (LiFePO4). A key advantage over other lithium-ion batteries is the superior thermal and chemical stability, which provides better safety characteristics than other lithium-ion batteries with different cathode materials. Due to the significantly stronger bonds between oxygen atoms in the phosphate, oxygen is not readily released, and as a result, lithium iron phosphate cells are virtually incombustible in the event of mishandling during charge or discharge, and can handle high temperatures without decomposing. Ships as USA or EURO version based on delivery address. BAT100A replaces BAT100 effective June 2011. Operation 1. Only charge the BAT100A (12 v @ 15 AH LiFePO4) using the included charger. 2. Discontinue use of the BAT100A when the performance of the MP System begins to deteriorate. Charging the Battery Pack 1.

The kit comes with a Smart Sensor connector, cable and components to properly interface with the transducers. The kit will allow quarter, half or full bridge transducers (pressure, force, strain, acceleration, sound, etc.) to be connected to the system. SS-KIT-IN COMMENTS AND SUGGESTIONS 1) Be careful of consumption. The bridge circuit should be designed so no more than 5mA are used to power the bridge. If the bridge takes more than 5mA, try reducing the voltage across the bridge by using series resistors or other kinds of regulators. Schematic 2) Be careful of signal amplitude. The signal input (conditioned by the bridge) should provide a signal no greater than ±50 mV between pins 2 and 4 on the 9 Pin D Male connector. If this voltage exceeds 50 mV (of either polarity), the input amplifier stages will saturate.

Typical uses are: 1. Synchronizing 3rd party equipment to the MP3X’s start of acquisition. 2. Listening to pulses (“clicks”) or tones with headphones which can be used for reaction time studies. 3. Controlling audio or visual stimulus device (Audio tone, LED or Strobe flash, etc.). 4. Listening to input signals such as EMG via headphones or an audio amp./speaker. Typical Analog Out connections include: Analog Out Function MP36/MP35 and MP30 Listening to pulses (“Clicks”) via headphones or audio amp./speakers Headphone “+”: pin 1 Headphones “-“: pin 3 Headphones for listening to analog signals (EMG, etc) Headphone “+”: pin 1 Headphones “-“: pin 3 Driving output LED’s “+”: pin 2 “-“: pin 3 To limit LED current, put resistor in series with pin 2. Synchronizing to 3rd party equipment Out “+”: pin 5 Out “-“: pin 3 The “Analog Out” port on the back panel of the MP36/MP35 or MP30 (MP3X) can output pulses (digital) or analog voltage levels, or it can pipe out analog signals from one of the input channels. The port is controlled through one of the Output Control Panels in the Biopac Student Lab (BSL) PRO software, which is described in the BSL PRO manual. The following diagrams and table show the pin-outs of the “Analog Out” port on the back of the MP3X and the Printed Circuit Board (PCB) layout of the SS-KIT-OUT. Each pin is accessible on the PCB and can be located by the label shown in the table. 9 PIN MALE DSUB Back Panel—MP36/MP35 or MP30 SS-KIT-OUT PCB ANALOG OUT PORT BIOPAC Hardware | SS-KIT | Page 2 - 3 Updated: 3.28.2013 info@biopac.com support@biopac.com www.biopac.com HARDWARE GUIDE SS-KIT-OUT SPECIFICATIONS PIN LABEL on PCB 1 AC_OUT 2 DC_OUT 3 4 5 GND 5V STR 6 7 8 9 12V SCL SDA LIN Notes Pins 1 and 2 Pins 3, 4 and 6 PIN FUNCTION MP36/MP35 Buffered analog or pulse output A.C. coupled (1,000 uF) Analog range: +/- 2.048 V Pulse range: 0 to 2.048V Buffered analog or pulse output D.C. coupled Z out = 50 Range: 0 to 4.096 V Ground +5 V (100mA max.)

When run under previous firmware, pins 1 and 2 can only be used for analog output. To identify the firmware revision, launch the BSL PRO software and check the Help > About Biopac Student Lab dialog. See the Support section at www.biopac.com for upgrade information. The Power supply pins (3, 4 and 6) can be used for external circuits as long as the load current does not exceed 100 mV. ASSEMBLY NOTES The PCB assembly fits into the thumb screw housing as shown. Two screws attach the PCB to the housing and hold the strain relief in place. The strain relief is used to prevent the cable and attached wires from pulling off the SS-KIT-OUT PCB. It is a good idea to place the strain relief over the cable prior to soldering the wires to the PCB so that it only has to be slid on a small distance. If the strain relief fits too tightly around the cable, use water to wet the cable, allowing the strain relief to slide. Place the strain relief such that the case cover pinches and holds the cable. The stick on panel is used to cover the screws and protect the label.

It can present visual stimuli on a computer screen, or auditory stimuli via headphones or speakers, and simultaneously (1ms resolution) send trigger signals to an MP36/35 System for data synchronization and collection purposes. For performing accurate (1 ms resolution) reaction time measurements, the STP35W includes a six-pushbutton response box. For measuring physiological responses to stimuli, the STP35W includes an optically isolated interface, permitting up to three synchronization signals (input) between the STP35W and the MP36/35 System. The SuperLab software can be used to change the placement of visual stimuli on the screen, change the screen's background color, choose from a variety of input and timing options, and provide feedback to subjects based on either response or reaction time. Different trigger channels can be paired to different visual or auditory stimuli to perform sophisticated evoked response averaging tests (e.g. P300). See BSL PRO Lesson H30 Stroop Effect for details of the classic psychology experiment and a sample of how SuperLab works with the BSL System. NOTE: Second PC required. The synchronization signal(s) coming from the STP35W can be directed to a BSL MP36/35 System running on a PC or a Macintosh, but it's not possible to run the STP35W on the same computer as the BSL MP36/35 System. The STP35W requires that the SuperLab software and a Digital I/O card (PCI slot required) be placed on a second computer. STP35 MP36/35 TO SUPERLAB For users who already have SuperLab and an MP3X unit, the STP35 Interface Cable can be used to connect the two systems. The STP35 cable interfaces with the I/O port of the rear of the MP36/35 unit.

The System includes all of the glassware, tubing, reservoir, tissue hooks and mounting accessories, force transducer and micrometer tension adjuster. The ergonomic design of the station allows the tissue bath to be lowered away from the tissue holder so that mounting of the tissue preparation is very easy. The taps for filling and draining the bath are mounted on the tubing to avoid the risk of accidental bath breakage. The entire station is mounted on a convenient base stand, which creates a sturdy platform for the experiment. The unique design makes it easy to add or remove stations to provide the optimal solution for the requirements. When a system is ordered, the size of the tissue bath and heating coil must be specified. Each Tissue Bath station includes: 1 Reservoir 1 Reservoir Holder 1 Transducer Holder 1 Warming Coil Holder 1 Warming Coil (specify 5 ml, 10 ml, 20 ml, or 30 ml size) 1 Tissue Holder (glass; left) 1 Tissue Holder (stainless steel; right) 2 Triangle Tissue Holder (stainless steel) 2 Tissue Clip (stainless steel) 1 Bath Holder 1 Tissue Bath (specify 5 ml, 10 ml, 20 ml size) 1 Oxygen Filter (glass) 1 Micrometer Assembly 1 Mount Accessories Kit 1 Base Station with Support Rods 1 TSD125 Force Transducer (specify TSD125 model C, D, E or F) See also: BIOPAC Circulators, or use an existing system.

Circulator A: 110 V, 60 Hz Circulator B: 220 V, 50 Hz CIRCULATOR SETUP AND USAGE GUIDE BIOPAC Heating Circulators will maintain water temperature at a preset value in the range 300C to 450C and circulate the water through tissue baths. Heating circulators include a digital temperature display and the following controls: Preset Temperature Power Heater Circulation CALIBRATION Although the offset value for the temperature sensor is factory-calibrated, the user can calibrate the controller’s internal temperature sensor. To calibrate the sensor: 1. Install a calibrated reference thermometer in the bath. 2. Adjust the offset value to zero. 3. Adjust the preset value to an appropriate temperature. 4. Once the bath reaches the preset value and stabilizes, calculate the offset value by noting the difference between the reference thermometer value and the preset value. 5. Enter this value as an offset. ERROR CODES Display Lo Indication Water in the bath is not enough or the bath is empty. Sen Microprocessor cannot communicate with the temperature sensor. BIOPAC Hardware | ITBS Circulator | Page 1 - 3 Updated: 2.6.2013 HARDWARE GUIDE info@biopac.com support@biopac.com www.biopac.com CIRCULATOR SETUP & USAGE GUIDELINES 1. Connect a hose from the INLET on the back of the circulator to the tissue bath OUTPUT. For more than one tissue bath, connect the tissue baths serially. 2. Connect a hose from the OUTLET on the back of the circulator to the tissue bath INPUT. 3. Fill the stainless steel water bath with 4.5 liters of water. A buzzer sound warning will be emitted if there is not enough water in the bath when the Circulator is powered on. See Error Codes above. 4. Place the glass lid on the bath to close. 5. Plug the power cord from the back of the Circulator to a power source. 6. Press the POWER key to turn on the circulator. 7. To see the preset temperature value, press the P.SET key.
