7.2 - Probe Calibration

The options of CAL>PROBE are:
ºC: Adjust of the internal temperature sensor (internal Probe). : Adjust of the internal temperature sensor (internal Probe). : Adjust of the internal temperature sensor (internal Probe).
RESTORE: Restores the internal temperature sensor calibration parameters to : Restores the internal temperature sensor calibration parameters to : Restores the internal temperature sensor calibration parameters to
the factory values.
To readjust the internal Probe it is necessary to compare the value indicated by To readjust the internal Probe it is necessary to compare the value indicated by To readjust the internal Probe it is necessary to compare the value indicated by
the calibrator (Probe) and the temperature value from an external probe placed in the calibrator (Probe) and the temperature value from an external probe placed in an the calibrator (Probe) and the temperature value from an external probe placed in an
insert. The temperature of the external probe should have high accuracy and should be insert. The temperature of the external probe should have high accuracy and should be insert. The temperature of the external probe should have high accuracy and should be
measured by a superthermometer (ST).
The option to adjust the internal sensor has seven points of adjustment. These The option to adjust the internal sensor has seven points of adjustment. These The option to adjust the internal sensor has seven points of adjustment. These
points are recorded via keys 1 to 7.
Before starting the calibration (adjustment), record in these points the respective Before starting the calibration (adjustment), record in these points the respective Before starting the calibration (adjustment), record in these points the respective
