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.
Note
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.

Storing Data
The 566 thermometer can store up to 20 data records. The 568 thermometer can store up to 99 data records. The following information is stored in each record:

• Record number
• IR and probe temperature in °F or °C
• Date/Time
• Emissivity
• Max/Min/Avg/Dif Temperature (if enabled)

For more information, see “Save”.

Downloading Data
The stored data of the 568 can be downloaded to a personal computer (PC) via the included USB cable and the included FlukeView® Forms Documenting Software. See the FlukeView® Forms documentation for details. The USB input 2 is located on the top of the thermometer next to the external probe input 1  (see Figure 9).

Note
To prevent incorrect readings, do not perform a temperature measurement of an earthed conductor while the 568 is connected to a PC that is earthed by a three-phase grounding plug.

External Contact Probe

Warning
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.
