Operating Manual for Digital Quick-Response Thermometer

GTH 1150C

Points to be observed during operation

1. As soon as „BAT“ is displayed the battery is used up and needs to be replaced immediately as too low operating voltage
may result in incorrect measurements. Unless the battery is replaced immediately the voltage will not even be enough to
display “BAT”. Therefore, make it a rule to always check the battery – even if no ‘BAT’ warning is displayed – if measuring
results are incorrect.

2. Make sure to maintain device properly and to operate it in accordance with the specification listed (do not throw, knock etc.).

3. Make sure that sensor and device are always subjected to the same temperature, i.e. try to avoid holding sensor plug in
your hand for a longer periode of time as well as subjecting device to an additional heat source as this may result in
measuring inaccuracies.

4. The length of the measuring sensor GTF300 can be reduced as desired so that it will be fully operational again after
sensor has been broken. To do so, please strip both wire ends for approx. 10mm and twist well. Measurements are not
possible as long as wire ends are exposed.

5. The battery has to be taken out, when storing device above 50°C.
It is recommended to take the battery out, when storing device for a longer period of time

General:

The GTH1150C are digital pocket thermometers for quick response temperature measurements.
Depending on the used measuring probe measurements on surfaces, in liquids, soft media, air/gases, at smallest objekts,
etc. are possible.

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
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 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).
