8 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 is smaller than spot size.
⇒
Choose correct measuring distance
•
Measuring object is not always in the measuring spot of the pyrometer (e.g. swinging
wire or pouring stream)
⇒
Use max. value storage
•
Emissivity set too high
⇒
Set lower correct emissivity corresponding to the material
•
Lens contaminated
⇒
Clean lens carefully
Temperature indication too high
•
Emissivity set too low
⇒
Set higher correct emissivity corresponding to the material
•
The measurement is influenced by reflections of hotter machine parts
⇒
Try to avoid the influence of the interfering radiation or change measuring position
Measuring errors
•
Indicated temperature is decreasing during the use of the pyrometer, contamination of
the lens
⇒
Clean lens
•
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
•
Air contamination in the sighting path between pyrometer and object
⇒
Change position of the pyrometer with a clean sighting path
•
Strong HF-interferences
⇒
Change position of the pyrometer
•
Instrument overheated
⇒
Use cooling jacket with air or water cooling
•
Temperature Indication is fluctuating, probably caused by changing emissivity
⇒
Wrong pyrometer type, use of ratio pyrometer recommended
Laser targeting light
•
Laser targeting light fails
⇒
Instruments max. temperature is exceeded. Use cooling jacket
