Introduction
The Fluke Models 63, 66, and 68 Infrared Thermometers (“the
thermometers”) are for non-contact temperature measurement.
These thermometers determine an object’s surface temperature by
measuring the amount of infrared energy radiated by the object’s
surface. See Figure 2.

Safety Information
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
• 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 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.
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 thermometer to stabilize before use).
• Do not leave the thermometer on or near
objects of high temperature.

How the Thermometers Work
Infrared thermometers measure the surface temperature of an
opaque object. The thermometer’s optics sense emitted, reflected,
and transmitted energy, which is collected and focused onto a
detector. The unit’s electronics translate the information into a
temperature reading which the unit displays. The laser is used for
aiming purposes only. See Figure 3.

Temperature Measurement
To measure temperature, point the unit at an object and pull the
trigger. Be sure to consider distance-to-spot size ratio and field of
view. The laser is used for aiming only.
Locating a Hot or Cold Spot
To find a hot or cold spot, aim the thermometer outside the desired
area. Then, slowly scan across the area with an up and down
motion until you locate the hot or cold spot. See Figure 4.

Distance and Spot Size
As the distance (D) from the object being measured increases, the
spot size (S) of the area measured by the unit becomes larger. The
relationship between distance and spot size for each unit is shown
in Figure 5. The focal point of each unit is 914 mm (36 in). The spot
sizes indicate 90 % encircled energy. See Figure 5.

Field of View
Make sure that the target is larger than the unit’s spot size. The
smaller the target, the closer you should be to it. See Figure 6.
Figure 6. Field of View
ame004.eps
Emissivity
Emissivity describes the energy-emitting characteristics of
materials. Most organic materials and painted or oxidized surfaces
have an emissivity of 0.95.
The 63 has a preset emissivity of 0.95. To compensate for
inaccurate readings that may result from measuring shiny metal
surfaces, cover the surface to be measured with masking tape or
flat black paint (< 148 °C/300 °F). Allow time for the tape or paint to
reach the same temperature as the surface beneath it. Measure
the temperature of the tape or painted surface.
13
63/66/68
Infrared Thermometers
The 66/68 thermometers allow you to adjust the unit’s emissivity for
the type of surface being measured. Refer to Table 2.

top of the handle.
To toggle between °C and °F, slide the top switch to the
appropriate position. See Figure 2.
Trigger Lock (66/68)
To lock the unit on for continuous measurement, slide the bottom
switch down. See Figure 2. If the trigger is pulled while the unit is
locked on, the laser and backlight will turn on if they have been
activated. When the unit is locked on, the laser will turn off when

the trigger is released. However, the backlight remains on unless it
is turned off using the keypad.
Backlight and Laser On/Off Switch (63)
To turn the backlight and laser on or off, slide the backlight and
laser switch to the appropriate position. See Figure 2.
Function Button Functions (66/68)
Models 66 and 68 measure Maximum (MAX), Minimum (MIN),
Differential (DIF), and Average (AVG) temperatures each time a
reading is taken. DIF shows the difference between maximum and
minimum temperatures measured. AVG shows the average
temperature reading for each time the trigger is pulled or the unit is
locked on. This data is stored and can be recalled with
new measurement is taken. See “Hold” for information on how to
recall stored data. When the trigger is pulled again, the unit will
