36.1 Temperature check
The temperature check is performed using a high-precision thermometer. Place the ther-
mometer on each zone and verify the temperature. Calibrate if necessary.
Please refer to the "13.4.1 Temperature sub-menu" section for more information on how
to perform the temperature calibration.
PASS:
•
All temperatures measured on the bottom of the compartment in the loca-
tions where the dishes would be placed must not deviate more than ± 0.2
°C
from the setpoint.
•
All temperatures measured on the lid must not deviate more than ± 0.5
°C
from the setpoint.
36.2 CO
2
gas concentration check
The CO
2
gas concentration is checked for deviations. The gas sample port on the side of
the unit is used for this. Use sample port-2 for validation. It is essential to have a high-
precision gas analyzer for CO
2
and O
2
available to do the test.
Please follow these simple rules while testing gas concentration:
•
Check the CO
2
gas setpoint.
•
Check the actual CO
2
gas concentration to ensure the setpoint is reached, and gas
concentration is stabilized around the setpoint.
•
Remember not to open any lids for at least 10 min, before starting the test or dur-
ing the testing itself.
