Infrared Thermometer
Introduction
The Fluke 561 HVACPro Infrared Thermometer (hereafter, “the Thermometer”) can determine the surface
temperature by measuring the amount of infrared energy radiated by the target’s surface or by contact
using a thermocouple probe. The Thermometer was designed specifically for use in heating, ventilating, and
air conditioning (HVAC) applications. This manuals covers all versions of the the Fluke 561.

Safety Information
XWWarning
A Warning identifies conditions and actions that pose hazards to the user. To avoid electrical
shock or personal injury, follow these guidelines:
• * Do not point laser directly at eye or indirectly off reflective surfaces.
• Before using the Thermometer inspect the case. Do not use the Thermometer if it appears
damaged. Look for cracks or missing plastic.
• Replace the batteries as soon as the battery indicator (B) appears.
• 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 connect the optional external probe to live electrical circuits.
• To avoid a burn hazard, remember that highly reflective objects will often result in lower
than actual temperature measurements.
• Do not use in a manner not specified by this manual or the protection supplied by the
equipment may be impaired.
WCaution
To avoid damaging the thermometer or the equipment under test protect them from the
following:
• EMF (electro-magnetic fields) from arc welders, induction heaters, etc.
• Static electricity.
• Thermal shock (caused by large or abrupt ambient temperature changes- allow 30 minutes
for the Thermometer to stabilize before use).
• Do not leave the Thermometer on or near objects of high temperature.
Table 1 and Figure 1 show various symbols and safety markings that are on the Thermometer and in this
manual.

Display
The primary temperature display reports the current or last IR temperature read until the 7-second hold
time elapses.
The secondary temperature display reports current thermocouple temperature when a type-K thermocouple
is attached. When a thermocouple is not connected, the small temperature display reports a choice of
maximum, minimum, or difference between maximum and minimum temperature.
You can toggle through the minimum, maximum, and difference IR temperatures anytime the display is on.
The MIN, MAX, and DIF temperatures are constantly calculated and updated when the trigger is pressed.
After the trigger is released, the MIN, MAX, DIF temperatures are held for 7 seconds.
Note
When the battery is low, B appears on the display.
The last selection (MIN/MAX/DIF) is maintained on the secondary display even after the Thermometer has
been turned off, providing the batteries have not failed.
