Product Overview
Research Instruments Ltd
SECTION 4 - PRODUCT OVERVIEW
RI Witness is a system which operates within an assisted reproduction (AR) clinic setting and provides
a method of identifying human samples throughout an AR cycle (from egg and sperm collection to
embryo transfer). The system is intended to minimise the risks associated with traditional/manual
double-checking and provides the essential controls necessary to ensure eggs, sperm and embryos are
correctly matched and treated during the AR process.
The RI Witness system comprises hardware, firmware and software components, which can be
configured depending on the treatment activities, number of AR cycles conducted, size and layout of
the AR clinic.
RFID (radio frequency identification) technology provides the means of identifying the containers
(dishes, tubes) in which eggs, sperm and embryos are transferred and stored. The containers are
labelled by a clinician with a special RFID tag which has been assigned a unique identifier. The unique
identifier is linked to a patient/couple (specific parentage).
As samples are processed as part of an AR cycle, RFID readers (both heated and non-heated) read the
tags on the container and their identity and status is confirmed on-screen. If containers containing
samples of incompatible origin come into contact at any stage of this process, the system activates an
alarm and prompts the clinician to respond.
This manual is specifically for the Embryology Heated Plate (and associated Tube Reader accessory) in
both its flush fitted and sit on top configuration.
Other devices in the RI Witness range have their own manuals, as does the software.

SECTION 5 - RI WITNESS BASIC OPERATION
Startup Procedure
To turn the device on, plug the power cable from the device into the power supply in-line connector
ensuring it is fully inserted. Then plug the power supply into the wall power outlet.
Figure 5-1 Power Supply In-Line Connector
Once the device is plugged in, it will display the current measured temperature on the display. The
status LED will remain off until the temperature has stabilised at the specified setpoint. The time to
reach this will vary according to the ambient temperature, but will generally be within 15-30 minutes.
Once the temperature has stabilised, the green status light will illuminate (see “Alarms and System
Status” on page 18 for more information).
RI suggests that you keep the RI Witness computers and work areas (including the Embryology Heated
Plate) switched on. This means that the heating and monitoring is constant.
Shutdown Procedure
To shutdown the device remove all electrical power by disconnecting the cable from the electrical
outlet.
Connecting to the Software
Plug the device into the tablet or PC (or attached USB hub) using the USB A cable that protrudes from
the device. Once the Windows operating system has recognised the devices within the Embryology
Heated Plate, open the RI Witness WorkArea software. To verify that the RI Witness Work Area software
can communicate successfully, navigate to the Work Area Status window (click the yellow triangle or
press the (i) icon). This will bring up the Work Area Status window where the ‘Embryology Reader’ and
‘Temperature Control’ should be listed in the Connected Devices section with a green tick next to them.
For more detailed set up information, refer to the RI Witness software manual (6-70-121UM).
User Interface
The Embryology Heated Plate contains a built in user interface which allows access to basic temperature
setpoint and calibration adjustment. A complete set of calibration options can only be accessed through

Ambient temperature must be >5°c from the set point for the temperature control
to work effectively
Place only plastic or glass ware on the window heated area.
Temperatures within the Petri dish are adjusted by changing the setpoint temperature as described on
the next page. The temperature inside a Petri dish will normally be slightly lower than the heated plate,
depending on ambient conditions, type of Petri dish and the sample preparation. After the system has
been installed in its operating location, the temperature of the heated plate should be adjusted to allow
for this difference.
We recommend using a thermometer calibrated to 37°C fitted with a small thermocouple probe, such
as the RI IVF Thermometer to measure the temperature inside the Petri dish.
Prepare a Petri dish that mimics your normal Petri dish preparation and place it on the heated surface
in its normal position. Place the probe of the thermometer in the centre of the dish against the bottom
of the dish and allow the temperature reading to stabilise. Adjust the setpoint temperature until the
desired temperature in the dish is reached, allowing 20 minutes (or as long as required) in between
each setpoint change to allow the Petri dish temperatures to stabilise.

Research Instruments Ltd
RI Witness™ Basic Operation
Temperature Calibration
Note: Using the built-in user interface on the Embryology Heated Plate, it is only possible to calibrate
the temperature of the ITO glass window. To perform a full calibration of all 5 heated areas, this must
be done from within the RI Witness WorkArea software.
Perform calibration only if the displayed temperature is different to the actual surface temperature of
any of the 5 heated areas. The process of calibration allows the user to manually adjust the temperature
so that the displayed temperatures match the temperature of the surface.
Before temperature calibration can be performed the device must be in the same conditions that it will
be in during normal operation. The temperature calibration is affected by ambient conditions.
Place the probe of a calibrated thermometer in good thermal contact with the surface.
Note: Simply touching the probe on the surface is not adequate. Use a purpose-made surface probe and
use thermal transfer paste. Products sold for computer heatsinks are suitable, and RI can also supply
suitable materials. Wait at least 30 minutes to allow the temperature to stabilise before calibrating.
Heated areas are divided as shown below, with the ‘X’ denoting recommended thermocouple positions
for calibration:

6. After adjusting calibration check sample temperatures and adjust the setpoint temperature if
required.
Note: To exit the window calibration mode without saving changes, do not press any buttons
for 15 seconds and the device will return to normal operation. The Temperature Adjustment
Indicator light will go out and the Temperature Display will stop flashing.
Full 5-channel Calibration Using PC and RI Witness WorkArea Software
Full calibration of the 5 heated areas requires that each of the areas is calibrated in turn.
1. Open the RI Witness WorkArea software and navigate to the WorkArea Status window.
2. Click on the yellow triangle or the (i) icon then click WorkArea Settings, then Connected
Devices, then Temperature Controller, then Check Calibration. The screen will now show the
current temperature and calibration offsets of the five different heated areas.
Note: RF will be switched off automiatically when on the Temperature Control screen.
3. Each heated area is independent so the order of calibration is not important. Position the
thermocouple probe in one of the positions shown above.
4. Allow the reading to stabilise, then compare the temperature shown in the WorkArea software
with the thermometer reading.
5. A difference within ± 0.2°C is acceptable. If the readings are outside this increase the offset to
increase the reading displayed by the software, or decrease the offset to decrease the reading
displayed by the software to match the temperature displayed by the thermometer.
Allow a small delay for the offset change to register. When changing the offset, the temperature
controller will then begin controlling using the new settings, so the surface temperature of that
heated area may take a short time to re-stabilise.
6. Repeat this process for all 5 heated areas.
7. Once calibration is complete it is advisable to verify the temperature of each heated area to
check that temperature calibration has been carried out effectively. After adjusting calibration,
check sample temperatures and adjust the setpoint temperature if required.

Alarm System Testing
In order to test functionality of the alarm system hold down the
button for 3 seconds when there
are no active alarms. This will trigger a medium priority alarm signal, (3 audible pulses and 3 yellow
flashes of the status indicator light). This check should be performed at regular intervals to reduce the
chance of missing an alarm due to failed loudspeaker or status indicator light.
