9 Transport, packaging, storage
With faulty shipping the instrument can be damaged or destroyed. To transport or store the instrument,
please use the original box or a box padded with sufficient shock-absorbing material. For storage in humid
areas or shipment overseas, the device should be placed in welded foil (ideally along with silica gel) to
protect it from humidity.
The IN 2000 is designed for a storage temperature between -20 and 70°C with non-condensing conditions. A
storing out of these conditions can damage or malfunction the pyrometer.
10 Maintenance
10.1 Safety
Attention during pyrometer services. Should IN 2000 be integrated in a running machine process the ma-
chine has to be switched off and secured against restart before servicing the IN 2000.
10.2 Service
The instrument does not have any parts which require regular service, only the lens has to be kept clean.
The lens can be cleaned with a soft cloth in combination with alcohol (do not use acid solutions or dilution).
Also standard cloths for cleaning glasses or photo objectives can be used.
11 Trouble shooting
Before sending the pyrometer for repair, try to find the error and to solve the problem with the help of the
following list.
Temperature indication too low

Incorrect alignment of the pyrometer to the object

New correct alignment to achieve the max. temperature signal (see 6.1 )

Measuring object smaller than spot size

Check measuring distance, smallest spot size is at nominal measuring distance (see 6 )

Measuring object is not always in the measuring spot of the pyrometer

Use max. value storage (see 7.7 ).

Emissivity set too high

Set lower correct emissivity corresponding to the material (see 7.4 )

Lens contaminated

Clean lens carefully (see 10.2 )
Temperature indication too high

Emissivity set too low

Set lower correct emissivity corresponding to the material (see 7.4 )

The measurement is influenced by reflections of hot machine parts

Use mechanical construction to avoid the influence of the interfering radiation
Measuring errors

Indicated temperature is decreasing during the use of the pyrometer, contamination of the lens

Clean lens. Recommendation: use of air purge (see 5 )

Air contamination in the sighting path between pyrometer and object

Change position of the pyrometer with a clean sighting path (if necessary use a ratio pyrometer)

HF-interferences

Correct the connection of the cable shield (see 4 )

Temperature Indication is fluctuating, probably caused by changing emissivity

Wrong pyrometer type, use of ratio pyrometer recommended
