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.
Symptom
Probable Cause Comments
Temperature
indication too low Emissivity slope set too high Set lower correct emissivity
slope corresponding to the
material
See section 4.5
Temperature
indication too high Emissivity slope set too low Set lower correct emissivity
slope 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 (sighting
tube)
No temperature
indication at the
end of the pouring
stream Pouring stream is not in the spot of
the pyrometer New correct alignment of the
optical head (see
3.6 )
Optical head contaminated or
scratched Signal strength too low, clean
or change optical head
Recommendation: use of air
purge
Pouring stream is much smaller than
spot size, thus the signal strength is
too low (see
4.3
)
Choose shorter measuring
distance
No temperature indication during the
use of the pyrometer, although the
air purge unit is used Probably compressed air is not
clean or air failed. Clean optics
and use clean and oil free air
HF-interferences Correct the connection of the
cable shield
