Operating Instructions 

Thermo Scientific Alpha COND 1000 

 

12

Note: When calibrating with manual temperature compensation, the controller 
automatically changes from the preset process temperature to the calibration 
temperature.  After leaving the Calibration mode, the controller switches back to 
process temperature (for setting the calibration temperature and the process 
temperature, see section 7.2.1).
