Safety Information
WWarning
To avoid electrical shock or personal injury, follow these guidelines:
•
Before using the thermometer, inspect the case. Do not use the
thermometer if it appears damaged. Look for cracks or missing plastic.
Pay particular attention to the insulation around the connectors.
•
Disconnect the thermocouple(s) from the thermometer before opening the
case.
•
Replace the batteries as soon as the low battery indicator (B) appears. The
possibility of false readings can lead to personal injury.
•
Do not use the thermometer if it operates abnormally. Protection may be
impaired. When in doubt, have the thermometer serviced.
•
Do not operate the thermometer around explosive gas, vapor, or dust.
•
Do not apply more than the rated voltage, as marked on the thermometer,
between the thermocouple(s), or between any thermocouple and earth
ground.
•
Models 52 and 54: Measurement errors may occur if voltages on the
measurement surfaces result in potentials greater than 1 V between the
two thermocouples. When potential differences are anticipated between
the thermocouples, use electrically insulated thermocouples.
•
When servicing the thermometer, use only specified replacement parts.
•
Do not use the thermometer with any part of the case or cover removed.
Caution
To avoid damaging the thermometer or the equipment under test:
•
Use the proper thermocouples, function, and range for your thermometer.
•
Do not attempt to recharge the batteries.
•
To prevent explosion, do not dispose of batteries in fire.
•
Follow local laws or regulations when disposing of batteries.
•
Match the
+
and

polarities of the batteries with the battery case
markings.
