Safety Information

The Fluke Model 53 and Model 54 Thermometers (“the
thermometer”) are microprocessor-based, digital
thermometers designed to use external J-, K-, T-, E-, R-,
S-, and N-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 the meter
symbols in Table 2.

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 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.
