Introduction
The 561, 566 and 568 Infrared Thermometers (“the thermometers” or “the
Product”) 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. The thermometers also support contacttemperature measurement via K-type thermocouple.
Note that the Japanese models indicate Celsius only.

561 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, 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. See Figure 3.

How the Thermometers Work
Infrared thermometers measure the surface temperature of an 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 signal
into a temperature reading which the unit displays (see Figure 5).

Operating the Thermometer
Temperature Measurement
To measure temperature, point the thermometer at an object and pull the trigger.
You can use the laser pointer to help aim the thermometer. You may also insert
the K-type thermocouple probe for contact measurement. Be sure to consider
distance-to-spot size ratio and field of view (see “Distance and Spot Size” and
“Field of View”). The temperature appears on the display.
The laser is used for aiming purposes only and is not related to
temperature measurement.
The thermometer features an auto off function that automatically powers down
the thermometer after 20 seconds of inactivity. To turn the thermometer on, pull
the trigger.

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 6).

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 (D:S) for each unit is shown in Figure 7. The spot sizes
indicate 90 % encircled energy.

Field of View
For accurate measurements, 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 8).

Emissivity
Emissivity describes the energy-emitting characteristics of materials. Most
organic materials and painted or oxidized surfaces have an emissivity of
approximately 0.95, the default setting for the thermometer.
To compensate for inaccurate readings that may result from measuring shiny
metal surfaces, you can cover the surface to be measured with electrical tape or
flat black paint (<148 °C/300 °F) with emissivity set to 0.95. 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.
If you cannot paint or use tape, then you can improve the accuracy of your
measurements by either numerically adjusting emissivity or by using the
Emissivity Menu to access a table of some common materials. The
thermometers have numerically adjustable emissivity from 0.10 to 1.00 that can
be used in conjunction with the emissivities in Tables 3 and 4. Also, the
thermometers have a built-in table of the most common materials that can be set
from the Emissivity Menu. The built-in values are indicated in Tables 3 and 4.
HOLD
The display retains its last infrared measurement for twenty seconds when the
trigger is released, with HOLD appearing on the display. With the probe inserted,
the contact thermometer remains on. To freeze the infrared temperature when a
probe is not inserted, release the trigger until HOLD appears on the display.

The thermometers come with a bead K-type thermocouple probe. The probes
attach to the thermometers via the probe input located on the top of the
thermometer (see Figure 9).
With the probe installed, the probe symbol () appears on the display. The
probe can be used simultaneously while the thermometer is taking non-contact
measurements. The probe readings are shown below the non-contact
measurements. The thermometer will stay on when there is a probe inserted.
When used with a personal computer and FlukeView Forms (568 only), the auto
off feature is disabled.

The general purpose bead probe is an alternative, for quick, accurate surface
temperatures and air temperatures within ducts, vent temperatures.
Pipe clamp probes (2) are essential for tracking continuously changing
temperature differentials on hydronic tubing and pipe loops, and good for quick,
accurate refrigerant temperatures.
The insulation piercing probe provides a sharp tip to pierce pipe insulation and flat
probe tip for good surface thermal contact, air temperatures within ducts, and vent
temperatures.
Flexible Cuff Thermocouple Temperature Probe is a convenient way to attach a
thermocouple to a pipe while keeping hands free.
The piercing probe is the most versatile option. Good for checking air temperature
in ducts, surface temperature under carpets/pads, liquids, thermometer wells, vent
temperatures, and for penetrating pipe insulation.
The tapered probe is a good general-purpose gas and surface probe, with a good
length and low mass tip casing for faster reaction to surface and air temperatures.
