7.5 Calibration
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
To guarantee perfect control, we recommend to calibrate the appliance once a year.
For temperature adjustment, you will need a calibrated reference measuring device.

Example: Temperature deviation at 120 °C should be corrected.
1. Activate the adjustment setting. To do so,
press the activation key on the right side
of the
CALIB display. The display is en-
larged and the first calibration tempera-
ture – in this case 40 °C – automatically
highlighted.
Cal1 °C -0,2K
Cal2 100.0 °C +0,1 K
Cal3 180.0 °C -0,2 K

ance's working chamber.
7. Close the door and, in manual mode,
adjust the set temperature to 120 °C.

With Cal1, a calibration temperature below Cal2 can be programmed accordingly, and with
Cal3, a temperature above. The minimum difference between the Cal values is 20 K for univer-
sal ovens UN
.../UF... and 10 K for incubators IN.../IF...
If all calibration values are set to 0.0 K, the factory calibration settings are restored.
