Activating the calibration mode
• The unit must be switched OFF.
• To activate the mode for calibration of the unit, press the
„STOP“ and „PROGRAM“ buttons simultaneously and
switch the unit ON. Continue pressing the two buttons
until cross-dashes (— —— ——) appear in the display
and a „C“ appears in the Step display. The calibration
mode has now been activated. This can be abandoned
only by switching the machine OFF and then switching it
back ON again.
Procedure
1) The heating plate must first cool to below 40 °C. Introduce
the reference sensor  into the appropriate hole in the
heating plate .
2) Insert the plug  on the reference sensor into reference
socket  on the single platform.
3) Activate the calibration mode as described above.
4) The unit is now run up to the three temperatures 50 °C, 100
°C, and 150 °C. The displayed set-point for tempera ture
flashes while the plate is heating up. Once the tempe ra-
ture is stable, the display stops flashing and the measure-
ment is taken for the period of one minute. The unit then
proceeds to the next higher value for temperature.
The heating plate becomes very hot during the calibration
process. Do not touch it with your bare hands.
5) If the calibration proceeds without any problems, it lasts
approx. 30 minutes. On its conclusion, the word „End“
appears on the temperature display. The unit automati-
cally takes over the temperature values from the external
sensor and/or the corrections that result from them.
