9 Troubleshooting
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
Measuring object is not always in the measuring spot of the pyrometer
Use max. value storage (see 4.9
)
Emissivity set too high
Set lower correct emissivity corresponding to the material (see 4.5
)
Lens contaminated
Clean lens carefully (see 6.2
)
Temperature indication too high
Emissivity set too low
Set lower correct emissivity corresponding to the material (see 4.5
)
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 3.3
)
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 3.1
)
Temperature Indication is fluctuating, probably caused by changing emissivity
Wrong pyrometer type, use of ratio pyrometer recommended
