Infrared Thermometer
Introduction
The Fluke Model 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.

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:
• * 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.
Caution
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.
