MAINTENANCE
Our customer service representatives are available for application assistance, calibration, repair,
and solutions to specific problems. Contact our Service Department before returning any
equipment. In many cases, problems can be solved over the telephone. If the sensor is not
performing as it should, try to match the symptom below to the problem. If the table does not
help, call Calex for further advice.

temperature
(mA or mV outputs)
Erroneous
temperature
(thermocouple
output)
LENS CLEANING
Keep the lens clean at all times. Any foreign matter on the lens would affect measurement
accuracy. Blow off loose particles (if not using the air purge accessory) with an air 'puffer'.
GUARANTEE
Calex guarantees each instrument it manufactures to be free from defect in material and
workmanship under normal use and service for the period of two years from the date of purchase.

Probable Cause
No power to sensor
Target too small for
sensor's field of view
Target is a reflective
metal surface
Field of view
obstruction
Dust or condensation
on lens
Incorrect wire
connections
Output temperature
scale mismatch
No Cold Junction
Compensation (CJC) or
wrong type of
extension cable
Solution
Check power supply and wiring
Ensure the sensor's view is completely filled
by the target. Position the sensor closer to
the target to measure a smaller area.
Measure a non-reflective area, or paint or
coat a measurable area of the target to make
it non-reflective
Remove obstruction; ensure sensor has a
clear view of target
Ensure lens is clean and dry. Clean gently
with a soft lens cloth and water. If problem
recurs, consider using an air purge collar.
Check wire colour codes
Re-scale input temperature range on
measurement instrument to match sensor
Enable CJC on measurement instrument;
ensure extension cable and connectors are
of the correct thermocouple type
