OPERATION
Once the sensor is in position and the appropriate power, air, water, and cable connections
are secure, the system is ready for continuous operation by completing the following simple
steps:
1 Turn on the power supply (not required if connected by USB only)
2 Turn on the instrument or PC
3 Read / monitor the temperature
IMPORTANT
Be aware of the following when using the sensor:
• If the sensor is exposed to significant changes in ambient temperature (hot to cold,
or cold to hot), allow 20 minutes for the temperature to stabilise before taking or
recording measurements.
• Do not operate the sensor near large electromagnetic fields (e.g. around arc welders
or induction heaters).
• Electromagnetic interference can cause measurement errors.
• Wire must be connected only to the appropriate terminals.
• Do not open the sensor housing. This will damage the sensor and invalidate the
warranty.
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, see TROUBLESHOOTING and try to match the
symptom to the problem. If the table does not help, call Calex for further advice.
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’.
