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
2. Turn on the meter, chart recorder or controller
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.
maintenance
Our customer service representatives are available for application assistance, calibration, repair, and solu-
tions to specific problems. Contact our Service Department before returning any equipment. In many
