4. OPERATION INSTRUCTION
WARNING
Before using the meter inspect the case. Do not use the
meter if it appears damaged. Look for cracks or missing
plastic. Pay particular attention to the insulation around the
connectors.
Disconnect thermocouples from the meter before opening the
case.
Replace the batteries as soon as the battery indicator “ ”
appears. The possibility of false reading can lead to personal
injury.
Do not use the meter if it operates abnormally. Protection
may be impaired.
Do not operate the meter around explosive gas, vapor or dust.
Do not use the meter with any part of the case or cover
removed.
