IMPORTANT! Keep in mind after transport or storage!
After transport, storage or long periods of non-use, moisture can seep into the heating
elements (magnesium oxide).
For drying, the calibrator must be slowly heated up. During this process, the calibrator
has not yet reached the required insulation voltage for protection class I.
For drying the heating elements, heat the calibrator for at least 15 min to 400 °C.
Cool down the calibrator and switching off:
To avoid injuries or material damage, it is necessary to bring the calibrator into a defined op-
erational state.
CAUTION! Risk of burns!
Prior to transport or contact with the metal block ensure that it has cooled down suffi-
ciently; otherwise there is a risk of severe burns at the metal block and the test speci-
men.
In order to cool down the metal block quickly, set the set temperature to the value ze-
ro.
IMPORTANT! Mains failure or separation from the mains!
If there is a mains failure, or if the main switch is turned off, or upon removal of the
mains connection ("EMERGENCY STOP"), the built-in fan does not blow any more cooling
air.
Sufficient thermal de-coupling between the metal block, the tank and the housing is
nonetheless guaranteed
Set the set temperature to the value zero.
Wait until the metal block has reached room temperature.
Switch off the calibrator via the main switch.
Clean the calibrator after use (
§ 7.2).
