Be sure shafl and/or sensor is unstrained when attaching as this is the zero load reference, Strap transmitter and 9 volt battery to shafl or device being measured To secure transmitter and battery use fiberglass strapping tape (available at hardware stores), Alternatively, hose clamps, machined collars or other methods or devices may be used but care should be taken to avoid excessive compression on the transmitter and battery CAUTION: Avoid injury by standing clear of attached items which may come off during rotation if improperty secured! Solder an appropriate length of 4-conductor ribbon cable or suitable leads to gage or sensor (6 — 8 inches typical), Connect other and of ribbon cable leads to appropriate screw terminals on BTQOOO transmitter. Secure battery connector to appropriate screw terminals on BTBOOO. and attach to 9 volt battery. Sensor (strain say: shown) Transmitter, Battery and Sensor Connections 10. Position RAQDO magnetic-mount receiving antenna near transmitter. typically within 10 feet, Connect RAQOO receiving antenna to Antenna connection on rear panel of RDQOOO receiver, RDQOOO Rear Panel Connect 12VDC AC adapter (Model AC110 or AC220) to Power Input jack on RDQODO rear panel, Plug adapter into appropriate power source (wall outlet). Move RD9000 power switch to On, RD9000 Front Panel Flip Auto Zero switch down to remove the previously stored reference. Confirm that Full Scale switch is down (used only for scaling and trouble shooting).

If possible, rotate transmitter through complete range of motion to verify strong signal reception in all orientations. Connect recorder or other voltage readout device to Output terminals on rear panel of RD9000. Flip Auto Zero switch up to zero out any initial imbalance (sensor must be in unloaded state, e.g. no torque on shaft). Leave switch in up position during test to retain reference Auto Zero can be reset by flipping switch down and then back up again, (Sensor must be in unloaded state). Note: If before activating Auto Zero there is an initial offset of more than 25% of full scale, contact technical support at Binsteld Engineering. Set Filter switch at rear of RD9000 to desired position, up to activate 10 Hz low-pass filter (averages dynamic data) or down to allow full 500 Hz frequency response. Calibrate output voltage based on gain calculations determined mathematically as demonstrated in Appendix B: Simplified Torque calibrations. Adjust the gain of the chart recorder or readout device for the desired deflection. For example. if the system is calibrated to provide ttOVDC for t 10,000 inch-pounds, the recorder could be set to deflect 1 50 mm (the center of the chart is usually considered the zero or balanced position). The plotted output on the chart would then be scaled at 200 inch-pounds/mm. System is now ready to record data. 10 miillfliilill Appendix A: System Calibration The RD9000 is calibrated prior to shipping using instruments traceable to the United States National Institute of Standards and Technology (NIST). Calibration can be checked at any time with a NIST traceable reference such as a calibrated voltmeter Check the RDBODO calibration as follows: 1, 24 7. Turn the unit on and allow a 15 minute warm-up. Turn the Full Scale Adjust screw on the front panel fully clockwise, Flip the Full Scale switch on the front panel to the down position Connect a calibrated voltmeter to the Output on the rear panel of the RDQOODt Without the RD9000 receiving a transmitted signal (etg. transmitter not operating or R09000 channel selector set to an unused frequency) the Output should read negative full scale (—10 VDC t 0.01) Flip the Full Scale switch on the front panel to the up position. The Output should read positive full scale (+10 VDC 1: 0.01), It is recommended that the RDQODO be checked for calibration annuallyt lf found to be out of specification, it can be returned to Binsfeld Engineering Inc. for calibration for a nominal fee ($75.00, price subject to change) 11 Hi i I l l tiff I" I 11 Appendix B: TorqueTrak 9000 Specifications Sensor Input: Full (4-arrn) Wheatstone Bridge strain gage (350 ohm standard) Sensor Range (mia'ostrain, user selectable): Torque, Tension. ‘/A Bridge Gain Bending Compression Level Full Bridge, Full Bridge, Single Gage 4 Active Arms 2.6 Active Arms 1 Active Ann 5 1:1 25 1:1 923 500 5 1250 $3845 $1000 4 1500 $7692 12000 3 21000 t1538,4 $4000 2 £2000 £30768 28000 I 1 i4000 E1535 116.000 0 i8000 1123072 232.000 (Assumed gage iactor= 2.0) Sensor and Power Connection: Screw terminal black Transmitter Power Input: 7.5 to 12VDC Transmitter Battery Life: 12 hours (9V lithium, 350 ohm bridge, 25°C) Receiver Output Signal: t10 volts full scale Receiver Output Connection: S-way binding pos1$ (banana jacks) Receiver Power input: 12VDC (250mA max) (110VAC or 220VAC adapter supplied) Gain Error: 10r5%FS (unadjusted') Gain Drifl: 0.01%/°C Zero Error. 11% (unadjusted‘) 10,1%FS (alter AutoZero) Zero Drift: 0.01%FSI°C [‘Maximum errors which may be reduced by proper calibration] 12 Resolution: Frequency Response: Operaiing Temperature: BTQOOO Transmmer: RDQOOO Receiver: Weight BTQODD Transmitter: RDQOOO Receiver, Size: BTQOOO Transminsr: RDQOOO Receiver: 14 biis (tfull scale = 16354 points) 0 — 500Hz (-3dB typical @ 500Hz) -0 to 70°C ~0 to 70°C 2 oz (57 g) 3 lbs (1.4 kg) 1.05" x 195“ x 0.70" (27mm x 50mm x 18mm) 5.5” x 7.5" x1.5" (14cm x 19cm x 3,ch) 13 H I I l ill I lift!

Trim the Full Scale Adjust screw on the front of the RD9000 until the volt meter reads 866 volts.
