Safety Information
Contacting Fluke
The Fluke 53IIB and 54IIB 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.
To order accessories, receive assistance, or locate the
nearest Fluke distributor or Service Center, call:
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.

Users Manual
Table 1. Safety Information
W Warning
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 ( ) 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.
•

•
Reflective objects result in lower than actual temperature measurements. These objects pose a burn
hazard.
•
Do not operate the thermometer around explosive gas, vapor, or dust.
•
Do not connect to voltages > 30 V ac rms, 42 V pk, 60 V dc from earth ground.

Safety Information
Table 1. Safety Information (cont.)
W Warning (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.
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.
•
Match the + and − polarities of the battery with the battery case.

Using Memory
Using the Offset to Adjust for Probe Errors
Using Memory
Use the offset option in Setup to adjust the thermometer's
readings to compensate for the errors of a specific
thermocouple.
During a logging session the thermometer stores logged
readings in its memory.
1.
Plug the thermocouple into the input connector.
At the end of the logging session you can view the logged
readings on the display.
2.
Place the thermocouple in a known, stable
temperature environment (such as an ice bath or a
dry well calibrator).
You can also transfer the logged readings to a PC running
FlukeView Forms software. (See "Communicating with a
PC.")
3.
Allow the readings to stabilize.
4.
In Setup change the offset until the primary display
reading matches the calibration temperature. (See
"Changing Setup Options.")
FlukeView Forms displays the logged readings on an
online form, which you can print or store for later use.

Initial Conditions and Data Entries
Starting and Stopping Logging
Logged readings include initial conditions and data entries.
Setup, memory clear, and PC communications are
inaccessible during logging.
The initial conditions are the thermocouple type and the
offsets for each thermocouple input. You can only view
initial conditions using FlukeView Forms.
The data entries are a time stamp, the T1 reading, and the
T2 and T1-T2 readings (Model 54). You can view these
values by pressing  or using FlukeView Forms.
Temperature readings display 0.1 degree resolution in
FlukeView Forms.
The thermometer has 500 memory locations. The
thermometer stores 499 sets of temperature readings and
one set of initial conditions when logging continuously. It
stores 250 sets of temperature readings and 250 sets of
initial conditions when logging individual points manually.
