7.5 Calibration
To guarantee perfect control, we recommend to calibrate the appliance once a year.
7.5.1 Temperature adjustment
The appliances are temperature calibrated and adjusted at the factory. In case readjustment
should be necessary later on – for example due to influence of the chamber load – the ap-
pliance can be calibrated customer-specifically using three calibration temperatures of your
choice:
►
Cal1 Temperature calibration at low temperature
►
Cal2 Temperature calibration at medium temperature
►
Cal3 Temperature calibration at high temperature
For temperature adjustment, you will need a calibrated reference measuring device.

CALIB display. The display is enlarged
and the temperature adjustment option
is automatically highlighted.
