To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
Follow the manufacturer’s maintenance procedures when
Place ONLY thermocouples (type K, J, T, or E) in the thermocouple
Make sure your meter is set for the proper thermocouple type.
Be sure the thermocouple you use can withstand the temperature
extreme it may be exposed to in your service task.
Properly maintain your thermometer and calibrate it regularly.
Do not use if the thermometer has cracks or any other damage to
Disconnect thermocouple before replacing batteries or opening
Replace batteries when low battery indicator appears on the
screen. Low batteries can aversely affect thermometer accuracy.
Do not apply voltage to thermocouples. There should be no more
than 1V between any two thermocouples, and no more than 30V
between any thermocouple and earth ground.
