Safety Advices
This device has been designed, assembled and tested in accordance with the safety regulations for electronic measurement
devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special
safety advices will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other
devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special
safety advices will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other
climatic conditions than those stated under "Specification".
2. Moving the device from a cold to a warm environment may lead to malfunctions due to condensation. In such a case we
recommend waiting to allow device temperature to adjust to the ambient temperature before re-starting.
3. If device is to be connected to other devices the circuitry has to be designed most carefully. Internal connection in third
party units (e.g. connection GND and earth) may result in not-permissible voltages impairing or destroying the device or
another device connected.
Warning: If device is operated with a defective mains power supply (short circuit from mains voltage to output voltage)
this may result in hazardous voltages at the device (e.g. sensor socket).

Warning: If device is operated with a defective mains power supply (short circuit from mains voltage to output voltage)
this may result in hazardous voltages at the device (e.g. sensor socket).
4. If there is any risk whatsoever involved in running it, the device has to be switched off immediately and to be marked
accordingly to avoid re-starting.
Operator safety may be a risk, if :
- there is visible damage done to the device.
- the device is not working as specified.
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance

Correction table
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.
Calibration point 0°C: 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".
Calibration point scale: 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 correction 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.)
Please note : During the waiting time the device should have assumed ambient temperature (we recommend a temperature
of 20 to 25°C). Please avoid holding device in your hand as well as subjecting it to an additional heat source (e.g. radiator,
lamp, sun).
