Calibration (parameters / cc to /cr)

The controller off ers the possibility to calibrate values read by the probes. In particular, parameters /cc to /cr are used
to increase or decrease the values read by the probes connected to the analogue inputs, consistently with the unit of
measure.
/cc is the control probe calibration off set. The diff erence in temperature between the control probe value and the average
compartment temperature that is used to control the cooling system to the unit setpoint during steady state operation.
All units are provided with a factory default setting for optimal cooling control. This can be useful to adjust if there is a
discrepancy between the unit setpoint and the average cabinet temperature.
/cr is the product probe calibration parameter. The diff erence in temperature between the display probe value seen on
the User Interface display and the average compartment temperature at the unit setpoint during steady state operation.
All pharmacy units are provided with a factory default setting for the display to provide accurate reading compared to the
average cabinet temperature. This can be useful to adjust the display during unit calibration procedures.
CAUTION: This modifi cation may not be allowed by site procedures as it alters the measured value. Verify
that you have permission to make the modifi cation.
