IMPORTANT: To prevent the operator from accidentally changing the calibration offset, a special
keystroke sequence is required to access this function.
This menu item allows you to adjust the Chiller’s internal and/or external temperature reading to match that of a

For C1 (Internal Calibration Offset), the preceding operating parameter is Ub
For C2 (External Calibration Offset), the preceding operating parameter is C1
For C3 (External Calibration Offset), the preceding operating parameter is C2
3. Press and hold
the Units/Menu Button.
