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.
Page 6
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.
Page 7
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.
Battery. Getting Started Everything in this Users Manual applies both to Models 53 and 54 unless otherwise indicated. To become familiar with the thermometer, study the following: Table 2. International Symbols Complies with European Union directives. Complies with relevant Canadian Standards Association directives.
53 & 54 Series II Users Manual Display Elements Figure 2. Display Elements The thermocouple measurement includes an offset. See "Changing Setup Options." The displayed readings do not change. A shift function is in progress. Readings are being logged. Setup is in progress. Logged readings are displayed.
Buttons Press to turn the thermometer on or off. Press (CANCEL) to stop displaying the minimum, maximum, and average readings in the secondary display. (Shift function) Press (CLEAR MEMORY) to delete logged readings from memory. Press (PC/IR SEND) to toggle the IR port on and off.

Press to start or stop logging. During manual logging, the thermometer stores a single set of logged readings in memory each time you press Press to show logged readings and MIN MAX readings on the display.
Plug the thermocouple(s) into the input connector(s). Press to turn on the thermometer. After 1 second the thermometer displays the first reading. If no thermocouple is plugged into the selected input or the thermocouple is "open," the display shows "- - - -."...
See "Using Memory." The thermometer stores logged readings at the end of each logging interval. You can select a logging interval of 1 second (1), 10 seconds (2), 1 minute (3), 10 minutes (4), or user-defined ( You can also set the logging interval manually (0).
Changing Setup Options Changing the Offset You can adjust the thermometer’s readings to compensate for the errors of a specific thermocouple. See "Using the Offset to Adjust for Probe Errors." The allowable adjustment range is C or K, and Model 54: You can store individual offsets for T1 and T2.
53 & 54 Series II Users Manual Enabling or Disabling Sleep Mode The thermometer enters sleep mode if no button press occurs for 20 minutes. Pressing any button wakes the thermometer and returns it to its previous state. Press until the display shows...
Changing the Line Frequency For optimum rejection of line noise, set the thermometer for the local line frequency as follows: Press until the display shows Press to indicate that you want to change the line setting. Press as needed until the display shows (50 Hz or 60 Hz).
53 & 54 Series II Users Manual Displaying Temperatures Press to select the correct temperature scale. Hold or attach the thermocouple(s) to the measurement location. The temperature reading appears in the selected display. Model 54: Press to toggle between showing the T1, T2, and T1-T2 reading in the primary or secondary display.
Using the Offset to Adjust for Probe Errors Use the offset option in Setup to adjust the thermometer’s readings to compensate for the errors of a specific thermocouple. Plug the thermocouple into the input connector. Place the thermocouple in a known, stable temperature environment (such as an ice bath or a dry well calibrator).
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.
Clearing Memory When memory is full, appears on the display and logging stops. You can clear memory in normal or MIN MAX mode. Press (CLEAR MEMORY) to delete logged readings from memory. The display shows the following for 2 seconds. MEMORY Viewing Logged Readings Press...
The display shows "- - : - -" if the log is empty. Communicating with a PC You can transfer the contents of the thermometer’s memory to a PC using FlukeView Forms . The communication requires an IR (infrared) serial connection.
To ensure that the thermometer performs to its accuracy specifications, Fluke recommends that you calibrate the thermometer annually, starting one year after purchase. To calibrate the thermometer, contact Fluke for the Service Center nearest you or follow the calibration procedure in the service manual listed in "Replacement Parts and Accessories."...
