4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by
transport. Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can
occur.
▶
When unloading packed goods upon delivery as well as
during internal transport, proceed carefully and observe the
symbols on the packaging.
▶
With internal transport, observe the instructions in chapter
4.2 “Packaging and storage”.
If the instrument is transported from a cold into a warm environment, the
formation of condensation may result in instrument malfunction. Before
putting it back into operation, wait for the instrument temperature and the
room temperature to equalise.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport
(e.g. change in installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -20 … +50 °C [-4 ... +122 °F]
■
Humidity: 35 ... 85 % relative humidity (no condensation)
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, ammable atmospheres
Store the instrument in its original packaging in a location that fulls the
conditions listed above.

5. Commissioning, operation
WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g. corrosive,
toxic, carcinogenic, radioactive), and also with refrigeration
plants and compressors, there is a danger of physical injuries
and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
▶
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also be
followed.
To determine the positioning of the module in the desired object, use the
back of the thermometer - not the side with the LC display - as a template.
The recommended size of the recess is 59.5 x 25.5 mm.
For correct horizontal positioning, we recommend using a spirit level.
1. Create a recess (as described above) in the desired object.
2. Guide the cable and the sensor through the hole.
3. Place the module on the hole and then press lightly on the front (not on
the display!) until the thermometer snaps into place.
4. Now feed the cable and sensor out to a suitable location and x them.
The thermometer is ready for operation in its as-delivered condition.The
measured temperature is shown on the LC display.

Immunityagainstradiatedelds(DINEN61000-4-3)
Under certain conditions, increased indication errors of a maximum of
5 % may occur in the presence of strong electromagnetic elds with a
frequency range of between 80 and 90 MHz. These errors are reversible
and disappear as soon as the source of interference is removed. Do not
install the instrument near sources of strong electromagnetic elds, e.g.
radio transmitters.

WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g. corrosive,
toxic, carcinogenic, radioactive), and also with refrigeration
plants and compressors, there is a danger of physical injuries
and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
▶
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also be
followed.
CAUTION!
Physical injuries and damage to property and the
environment
If faults cannot be eliminated by means of the listed measures,
the instrument must be taken out of operation immediately.
▶
Contact the manufacturer.

Make sure that the temperature at the case does not exceed or fall below the permissible temperature.
2) When exceeding or falling below the scale range, the display starts ashing and no longer shows correct values.
Once the medium temperature is within the scale range again, the display switches back to display mode.
