2. Recalibration
The measuring device will be calibrated before leaving our works. A recalibration is, therefore, not necessary. If you want to
calibrate the device for an existing sensor, please proceed as follows: (calibrate 0°C before scale as otherwise correct
adjustment cannot be guaranteed).
Normally sensor adjustment by means of 0° C potentiometer is sufficent. We do not recommend a scale compensation in order
to maintain the specified accuracy of the device. If an accurate reference temperature is available, choose highest temperature
possible to calibrate the device.

Put ice cubes in a glass and pour cold water till ice cubes are almost covered. Put sensor
into glass, wait approx. 15 minutes, then stirr water with a spoonhandle. Wait for stable
value to be displayed, then turn zero point potentiometer (NP, Potentiometer next to
sensor connection) by means of a screw driver till display shows „000".
To set the pitch (Scale) a fixed reference temperature is required (the higher the better).
Subject sensor to this temperature and set respective display value according to corre-
tion table value (e.g. reference temperature 700°C --> value to be set: 711) by means of
pitch potentiometer (outer potentiometer).
Please note that boiling water should not be used as a temperature reference as the
boiling temperature is dependent on the atmospheric pressure.(If using a reference
thermometer stating the precise temperature you may, however even use boiling water.)
