9 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

Measuring object smaller than spot size

check measuring distance, smallest spot size is at nominal measuring distance (see 5 )

Emissivity set too high

Set lower correct emissivity corresponding to the material (see 6 )

Lens contaminated

Clean lens carefully (see 8.2 )
Temperature indication too high

Emissivity set too low

Set lower correct emissivity corresponding to the material (see 6 )

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

Indicated temperature is decreasing during the use of the pyrometer, although the air purge
unit is used. Probably compressed air is not clean or air failed

Clean the lens and use clean, dry and oil free compressed air

HF-interferences

Correct the connection of the cable shield (see 4 )

Instrument overheated

Use cooling jacket with air or water cooling
