► Adjust if temperature displayed on the monitor does not match measured chamber temperature.
► Value is factory-set to match an independent thermometer.
► Value can be changed from -10.0 °C to +10.0 °C.
NOTE ► If the variance is within acceptable limits, changing the offset value is optional.
► Probes in the bottle are connected to the monitoring system and sense chamber
temperature. These probes do not affect refrigerator setpoint.

► Independent thermometer, calibrated and traceable per national standards.
► Tape, to attach thermometer to temperature probe.
Measure the chamber temperature:
1 Remove the probe from the probe bottle.
2 Unscrew the cap from the bottle.
3 Tape the thermometer to the temperature probe, and place them in the bottle. The probe and
thermometer should be immersed at least 2” (50 mm).

Enter the new offset value:
► Lower the offset value to lower the displayed monitor temperature.
► Raise the offset value to raise the displayed monitor temperature.
EXAMPLE ► Measured temperature (at the probe bottle) is 4.0 °C
► Displayed temperature is 4.5 °C
