5.2 5.2 Troubleshooting Measurement Difficulties
If you experience measurement problems, review the following
troubleshooting steps:
Is the sensor window clean?
Clean the sensor window and reflective cup and repeat the measurement.
Is the target's surface non-metallic?
Coat metallic surfaces with a non-metallic finish and repeat the measurement.
Is the target's surface transparent?
Coat transparent surfaces with an opaque non-metallic finish and
repeat the measurement.
Alternatively, put a shiny metallic surface such as aluminum foil
behind the transparent target and repeat the measurement.
Was the instrument's nosepiece in contact with the surface?
Touch the nosepiece flush to the target's surface and repeat the
measurement.
If after applying all of the above solutions, the instrument's accuracy
is still in question, contact Exergen for further help.
