Calibrating Temperature
If temperature calibration is needed, the following steps can be taken:
Locate the reference instrument’s temperature sensor in close proximity to the
cabinet’s geometric center. Be sure that the stabilization times described earlier have
been satisfied prior to performing calibration.
At the calibrate screen, press the
(Temperature Calibrate) button.
Enter the temperature offset by using the keypad and pressing
(Enter) when
complete.
A positive value will move the temperature ‘up’ and a negative value ‘down’. Press the
‘home’ button and verify the proper temperature is displayed.
Temperature calibration (example)
If the chamber temperature display reads 40.0
C and the calibrated independent
sensor shows 40.3
C, set the temperature offset value to 0.3
C. If the calibrated
independent sensor shows 39.6
C, then the entered offset should be negative. In this
example the required offset to temperature would be -0.4
C.
