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.
