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.
