Operating Manual GTH 175/Pt

Intended use:

The GTH 175/Pt measures the temperature in liquids,
air/gas and soft media.
The measurement is performed with a Pt1000 probe,
permanently connected to the measuring instrument.

• High accuracy and precision are the strengths of the
GTH 175/Pt.

• The device can be used as a reference measuring
instrument for the calibration of other measuring

for electronic devices. However, its trouble-free operation and reliability cannot be
guaranteed unless the standard safety measures and special safety advises given
in this manual will be adhered to when using it.

1. Trouble-free operation and reliability of the device can only be guaranteed if it
is not subjected to any other climatic conditions than those stated under
“Specification”.
Transporting the device from a cold to a warm environment condensation may
result in a failure of the function. In such a case make sure the device tempera­ture has adjusted to the ambient temperature before trying a new start-up.

2. Whenever there may be a 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 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.

3. Warning: Do not use these product as safety or emergency stop device, or in
any other application where failure of the product could result in personal injury
or material damage.
Failure to comply with these instructions could result in death or serious injury
and material damage.

4. Do not heat the probe over 200 C

2. Low battery voltage, replace battery

Hint: when battery voltage falls to low, BAT warning cannot be indicated.

check the battery in case of implausible measuring values.

To change battery: Remove battery cover at the backside of the device (push
cover forward), change the battery and close the cover.

Operating and Maintenance Advice

The battery has to be removed, when storing device above 50°C.
Treat device and probes carefully. Use only in accordance with above specifica-

tion. (do not throw, hit against etc.).
Protect from soiling, especially in the area of the gas inlet at the front plate.
Du not pull at the probe cable!

Tip: We recommend to take out battery if device will not be operated for

some time!

Adjusting

The measuring device will be calibrated before
leaving our works. If you want to adjust the device,
please proceed as follows:

1.Zero point adjusting (0°C): Put ice cubes in a
glass and pour cold water until ice cubes are almost covered. Put sensor into
glass, and stir water. Wait for stable value and turn zero point potentiometer (NP)
by means of a screw driver until display shows "0.00"

2.Scale adjusting: For scale adjustment a known reference temperature is

needed. Expose the probe to the reference and adjust the display using the poten­tiometer “Scale”

Calibration Service
