Product Overview
Research Instruments Ltd

RI Witness is a system which operates within an assisted reproducon (AR) clinic seng and provides
a method of idenfying human samples throughout an AR cycle (from egg and sperm collecon to
embryo transfer). The system is intended to minimise the risks associated with tradional/manual
double-checking and provides the essenal controls necessary to ensure eggs, sperm and embryos are
correctly matched and treated during the AR process.
The RI Witness system comprises hardware, rmware and soware components, which can be
congured depending on the treatment acvies, number of AR cycles conducted, size and layout of
the AR clinic.
RFID (radio frequency idencaon) technology provides the means of idenfying 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 idener. The unique
idener is linked to a paent/couple (specic 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 identy and status is conrmed on-screen. If containers containing
samples of incompable origin come into contact at any stage of this process, the system acvates an
alarm and prompts the clinician to respond.
This manual is specically for the Embryology Heated Plate (and associated Tube Reader accessory) in
both its ush ed and sit on top conguraon.
Other devices in the RI Witness range have their own manuals, as does the soware.

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.
Once the device is plugged in, it will display the current measured temperature on the display. The
status LED will remain o unl the temperature has stabilised at the specied setpoint. The me 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 informaon).
RI suggests that you keep the RI Witness computers and work areas (including the Embryology Heated
Plate) switched on. This means that the heang and monitoring is constant.
Shutdown Procedure
To shutdown the device remove all electrical power by disconnecng the cable from the electrical
outlet.
Plug the device into the tablet or PC (or aached USB hub) using the USB A cable that protrudes from
the device. Once the Windows operang system has recognised the devices within the Embryology
Heated Plate, open the RI Witness WorkArea soware. To verify that the RI Witness Work Area soware
can communicate successfully, navigate to the Work Area Status window (click the yellow triangle or
press the icon). This will bring up the Work Area Status window where the ‘Embryology Reader’ and
‘Temperature Control’ should be listed in the Connected Devices secon with a green ck next to them.
For more detailed set up informaon, refer to the RI Witness soware manual (6-70-121UM).
The Embryology Heated Plate contains a built in user interface which allows access to basic temperature
setpoint and calibraon adjustment. A complete set of calibraon opons can only be accessed through

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 condions, type of Petri dish and the sample preparaon. Aer the system has
been installed in its operang locaon, the temperature of the heated plate should be adjusted to allow
for this dierence.
We recommend using a thermometer calibrated to 37°C ed 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 preparaon and place it on the heated surface
in its normal posion. Place the probe of the thermometer in the centre of the dish against the boom
of the dish and allow the temperature reading to stabilise. Adjust the setpoint temperature unl 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.

Note
Perform calibraon only if the displayed temperature is dierent to the actual surface temperature of
any of the 5 heated areas. The process of calibraon allows the user to manually adjust the temperature
so that the displayed temperatures match the temperature of the surface.
Before temperature calibraon can be performed the device must be in the same condions that it will
be in during normal operaon. The temperature calibraon is aected by ambient condions.
Place the probe of a calibrated thermometer in good thermal contact with the surface.
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 calibrang.
Heated areas are divided as shown below, with the ‘X’ denong recommended thermocouple posions
for calibraon:
During calibraon using the built-in user interface close the RI Witness WorkArea soware to
prevent interference with the thermometer reading.
1. Posion the thermocouple probe on the Window in the locaon shown above.
2. Press and hold the Sengs and buons simultaneously for 3 seconds.
The Temperature Adjustment Indicator light will ash. The Temperature Display will now
ash between the current temperature (which may be a changing value) and the leers CAL.
3. Adjust the value shown on the Temperature Display using the Up and Down buons
unl the temperature matches that shown on the external thermometer.
4. Save the calibraon by pressing and holding the Sengs buon for 3 seconds. A beep will
be heard.
5. The Temperature Adjustment Indicator light will go out and the Temperature Display will
now show the current temperature with applied calibraon. Leave the probe in posion and
once the temperature has stabilised at the setpoint, check that the calibraon is accurate.
Repeat the calibraon process if necessary. The green Status Indicator Light will illuminate once
temperatures have stabilised.

for 15 seconds and the device will return to normal operaon. The Temperature Adjustment
Indicator light will go out and the Temperature Display will stop ashing.
Full calibraon of the 5 heated areas requires that each of the areas is calibrated in turn.
1. Open the RI Witness WorkArea soware and navigate to the WorkArea Status window.
2. Click on the yellow triangle or the icon then click , then Connected
, then Temperature Controller, then . The screen will now show the
current temperature and calibraon osets of the ve dierent heated areas.
RF will be switched o automiacally when on the Temperature Control screen.
3. Each heated area is independent so the order of calibraon is not important. Posion the
thermocouple probe in one of the posions shown above.
4. Allow the reading to stabilise, then compare the temperature shown in the WorkArea soware
with the thermometer reading.
5. A dierence within ± 0.2°C is acceptable. If the readings are outside this increase the oset to
increase the reading displayed by the soware, or decrease the oset to decrease the reading
displayed by the soware to match the temperature displayed by the thermometer.
Allow a small delay for the oset change to register. When changing the oset, the temperature
controller will then begin controlling using the new sengs, so the surface temperature of that
heated area may take a short me to re-stabilise.
6. Repeat this process for all 5 heated areas.
7. Once calibraon is complete it is advisable to verify the temperature of each heated area to
check that temperature calibraon has been carried out eecvely. Aer adjusng calibraon,
check sample temperatures and adjust the setpoint temperature if required.
