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).
Reflected energy
Target
Figure 5. How the Thermometer Works

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.

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.

External Contact Probe

To avoid electrical shock or personal injury, do not connect the external contact probe to live electrical circuits.
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.
