Introduction
The Fluke Model 51 and Model 52 Thermometers (“the
thermometer”) are microprocessor-based, digital
thermometers designed to use external J-, K-, T-, and E-
type thermocouples (temperature probes) as temperature
sensors.
Use the thermometer only as specified in this manual.
Otherwise, the protection provided by the meter may be
impaired.
Refer to safety information in Table 1 and meter symbols
in Table 2.

Table 1. Safety Information
WWarning
A Warning identifies conditions and actions that pose hazards to the user. 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 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.

Table 1. Safety Information (cont.)
WWarning (cont.)
•
Model 52:
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
A Caution identifies conditions and actions that may damage the meter 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 throw batteries into a fire.
•Follow local laws or regulations when disposing of batteries.
