Infrared Thermometers Introduction The 566 and 568 Infrared Thermometers (“the thermometers”) are for noncontact 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 contact-temperature measurement via K-type thermocouple. Note that the Japanese models indicate Celsius only.
566/568 Users Manual Safety Information WWarning A Warning identifies conditions and actions that pose hazards to the user. To avoid personal injury, follow these guidelines: • *Do not point laser directly at eye or indirectly off reflective surfaces. • Replace the batteries as soon as the low-battery indicator appears. • Do not use the thermometer if it operates abnormally. Protection may be impaired. When in doubt, have the thermometer serviced.
Infrared Thermometers Symbols and Markings Symbols and Markings Table 1 and Figure 1 show various symbols and safety markings that are on the thermometers and in this manual. Table 1.

Infrared Thermometers Menu Overview Menu Overview There are many settings that can be easily changed by using the menu. Figure 2 shows the LCD and menu interface. Selecting the Menu softkey advances the menu to the next level. Table 2 is a top-level description of the menu. eyl01.eps Figure 2. Menu Navigation Table 2.
566/568 Users Manual The reading includes: • IR temperature • Thermocouple temperature (if connected) • Emissivity • Min/Max/Avg/Dif (if either Min/Max or Avg/Dif is enabled) • Date/Time You may also press the Cancel softkey to abort saving the reading. Light The thermometers are equipped with a backlit display with two brightness levels. The Light softkey is used to adjust the backlight brightness. The backlight is on each time the trigger is pulled.
Infrared Thermometers Menu Overview • To enter an emissivity value manually: 1. Press the No. softkey. 2. Use the down or up arrow softkey to change the entry. Hold down the up or down arrow softkey to increase the rate of change. 3. Press the Done softkey when finished to return to the main menu. Table 3. Nominal Surface Emissivity Material Value Material Value Default**** 0.95 Glass (plate) 0.85 Aluminum* 0.30 Iron* 0.70 Asbestos 0.95 Lead* 0.50 Asphalt 0.95 Oil 0.94 Brass* 0.
566/568 Users Manual 2. Press the Avg softkey. The display shows the present reading, average reading, the differential reading between max and min (designated by Δ), and the emissivity setting. Note Min, Max, Avg, and Differential readings are saved as part of the saved data when either Min/Max or Avg/Dif mode is enabled. Alarm The thermometers have a programmable high and low alarm to designate high or low readings depending on the thresholds entered.
Infrared Thermometers Menu Overview Setup From the Setup menu, the backlight, time and date, and display language can be changed. Backlight In normal use, the backlight is always on. Use this menu to change the backlight setting from on to off. Turning the backlight off conserves battery power. 1. Press the Menu softkey until Setup appears as the left softkey function. 2. Press the Setup softkey. 3. Backlight has an indicator next to it. To enter the backlight menu, press the Enter softkey. 4.

Language To change the displayed language: 1. From the main menu, press the Menu softkey until Setup appears as the left softkey function. 2. Press the Setup softkey. 3. Use the down arrow softkey move the indicator to Language. 4. Press the Enter softkey. 5. Use the down arrow to move the indicator desired language. 6.
Infrared Thermometers How the Thermometers Work 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 3). Reflected energy Target Transmitted energy Emitted Energy eyl002f.eps Figure 3.
566/568 Users Manual 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). eyl07.eps Figure 4.
Infrared Thermometers Operating the Thermometer 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 5. The spot sizes indicate 90 % encircled energy. 568 eyl06.eps Figure 5.
566/568 Users Manual 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 6). Yes No eyl05.eps Figure 6. Field of View 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.
Infrared Thermometers Operating the Thermometer 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”.
566/568 Users Manual External Contact Probe XWWarning 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 7). With the probe installed, the probe symbol (A) appears on the display. The probe can be used simultaneously while the thermometer is taking non-contact measurements.
Infrared Thermometers Maintenance Maintenance Battery Charge Use the battery charge symbols to gauge the approximate level of charge left on the batteries. Notes When in low battery mode, the thermometer does not store values. “Err” appears on the display if attempted. J Batteries are at 5 %. Before taking further readings, the batteries must be changed.
566/568 Users Manual Cleaning the Lens Blow off loose particles using clean compressed air. Carefully wipe the surface with a water-moistened cotton swab. Cleaning the Housing Use soap and water on a damp sponge or soft cloth. WCaution To avoid damaging the thermometers, do NOT submerge them in water. Do not use abrasive cleaners, they will damage the case. User Replaceable Parts and Accessories User Replaceable Parts See Table 5 for a list of replaceable parts. Table 5.
