Temperature Calibration
Temperature calibration can be performed with a calibrated temperature sensor inserted into each
chamber. To maintain a stable temperature and to prevent ambient air from entering the chamber,
it is important to use a temperature sensor with a flat cable allowing the chamber lid to be closed
during calibration.
We recommend the K-Systems F100 Precision Thermometer together with the Solid Temperature
Sensor for temperature calibration. If the calibration is not performed with the Solid Temperature
Sensor, CooperSurgical cannot guarantee correct calibration of the device.
NOTE:
The sensor and thermometer should be calibrated as a unit and only by an accredited test
house. Refer to the Thermometer instructions.
There are 6 different regulators in the
incubator; 5 regulators for controlling the
surface temperature of the chambers (tn-1
– tn-5) and 1 for the Dry Bath Cham ”Menu
items” on page 26.
Within each chamber zone there are two chambers. In order to make an accurate temperature
validation, it is strongly recommended you measure the temperature in both chambers within the
specific zone. For example, to validate the temperature of tn-1, the temperature of chamber 5 and
chamber 10 must be measured, and an average value calculated.
The following table shows which chambers are associated with each zone:
Zone name
Chambers in zone
tn-1
Chambers 5 and 10
tn-2
Chambers 4 and 9
tn-3
Chambers 3 and 8
tn-4
Chambers 2 and 7

1.
Place a dish insert in each chamber
2.
Switch on the incubator and wait for (at least) 30 minutes for the temperature to stabilize at the
setpoint (eg 37.0°C)
3.
Check that your temperature setpoint is set to 37°C
4.
With your calibrated external temperature sensor, first measure the Dry Bath Chamber (tn-6)
and calibrate this to the setpoint temperature, see”Menu items” on page 26. Ensure that
you have seen a stable temperature on your meter before you do any changes to the tn-6
settings. Adjust until you obtain a stable temperature equal to the setpoint
