2 Safety

2.1 Intended Use

The device is covered to measure temperature in different mediums.

G 1700:

To connect different Pt1000 probes, the device is equipped with a BNC socket. By
selecting a suitable temperature probe, it is possible to use the device in different
applications.

You can find an extract of the available temperature probes in the following table.

G 1710, -20, -30:

The device is equipped with a fixed connected temperature probe and can be used in
different applications, depending on the model.

The GF 1000 series temperature probes (GF 1T.../2T- ) are designed for a
measuring range from -70 °C … 250 °C. The exposition of the silicone cable and
handle up to 250 °C should be restricted to max. 2 hours. A permanent use until 230
°C is acceptable.

Personnel which starts up, operates and maintains the device has to have sufficient
knowledge of the measuring procedure and the meaning of the resulting measured
values, this manual delivers a valuable help for this. The instructions of the manual
have to be understood, regarded and followed.

The manufacturer will assume no liability or warranty in case of usage for other
purpose than the intended one, ignoring this manual, operating by unqualified staff
as well as unauthorized modifications to the device.

2.2 Safety signs and symbols

Warnings are labeled in this document with the followings signs:

Caution! This symbol warns of imminent danger, death, serious injuries
and significant damage to property at non-observance.

Attention! This symbol warns of possible dangers or dangerous
situations which can provoke damage to the device or environment at
non-observance.

Note! This symbol point out processes which can indirectly influence

operation, possibly cause incorrect measurement or provoke unforeseen

reactions at non-observance.

2.3 Safety guidelines

This device has been designed and tested in accordance with the safety regulations
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 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
(chapter 13 Specification).

2. If there is a risk whatsoever involved in running it, the device has to be

switched off immediately and to be marked accordingly to avoid re­starting.
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. Do not use these products as safety or emergency stop devices 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. This device must not be used at potentially explosive areas! The usage

of this device at potentially explosive areas increases danger of
deflagration, explosion or fire due to sparking.

5. This device is not constructed for use in medical applications.

6. Due to the pointed probe design there is a risk of stitch injury for
devices with insertion probe.

7. Consider when measuring in food:
According to the regulation (EG) 1935/2004 the following parts of the

equipment are laid-out for the permanent contact with food :

• The stainless steel tube from the temperature probe of the
measuring tip till approx. 1 cm before the probe handle

Probe handle, connector cable and the device housing are not
construed for the permanent contact with food.

3 Product description

3.1 Scope of delivery

The scope of supply includes:

• Device with 2 batteries type AA

• Fixed connected temperature probe (not G 1700)

• Operating Manual

• Calibration protocol

3.2 Operating and Maintenance

1. Temperature measuring / probe connection:
For the models with fixed connected probes, the device is factory-adjusted to the

temperature probe – here the highest system accuracy can be achieved.
To optimize the accuracy, an offset and a slope correction can be executed at the
G 1700 (take a look at chapter 8 Adjustment of temperature input).

By the devices with fixed connected temperature probes, it is not necessary.

2. Battery operation:
If the battery has been used up and needs to be replaced, the empty frame of the
battery symbol starts blinking. The device will, however, continue operating
correctly for a certain time.
The battery has been completely used up, if ´bAt´ is shown in the main display.
Battery replacement: (see chapter 10 Replacing batteries).

The battery has to be removed, when storing device above 50°C.
We recommend taking out the batteries if device is not used for a longer

period of time.

3. Treat device and probes carefully. Use only in accordance with above specification.
(do not throw, hit against etc.). Protect plug and socket from soiling.
