Fluke 54 Thermometer
Laboratory accuracy.
Wherever you go.
The Fluke 54 Series II contact thermometer
offers fast response and laboratory accuracy
(0.05 % + 0.3 °C) in a rugged, handheld
test tool.
Key features:
• Relative time clock on MIN, MAX, and AVG
provides a time reference for major events
• Electronic offset function allows compen-
sation of thermocouple errors to maximize
overall accuracy
• Readout in ºC, ºF, or Kelvin (K)
• Splash and dust resistant case protected by
impact absorbing holster
• User-friendly front panel is easy to set up
and operate
• Sleep mode increases battery life; typical
1000-hour battery life
• Battery door allows easy battery replacement
without breaking the calibration seal
• Large backlit dual display shows any
combination of T1, T2, T1-T2, plus MIN,
MAX, or AVG
• Recall function allows logged data to be
easily reviewed on the meter display
• IR communication port allows data to be
exported to optional FlukeView

Carbon
monoxide
Use a carbon monoxide
meter to check for CO leaks
around the heat exchanger,
flue and other points
within a building.
Control voltage
Use a voltage detector or
DMM to test for energized
24 V ac contacts. Use an
infrared (IR) thermometer to
check for loose connections
or overloaded circuits.
Belts and
bearings
Use an infrared
thermometer to
check belts for
alignment and
bearings for
excessive
friction.
Air temperature difference
Check the temperature difference across the heat exchanger
with a digital thermometer, with the burner working. Expect
a 40-75 °F temperature difference (TD). If the TD is low, then
the fan is running too fast. If the TD is high, then the fan is
running too slow or there is restricted air flow.
Flame rod µA test
Verify proper operation of the flame
rectification circuit with a clamp meter or
digital multimeter in the µA mode. Compare
measured value against flame control module
specifications. Typical values vary widely and
can be as low as 0.16 to 18.0 µA or more.
If the µA reading is below specification,
the flame rod may need to be
repositioned, cleaned, or replaced.
