1 Infrared Thermometers Introduction The 566 and 568 Infrared Therm ometers (“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.
566/568 Users Manual 2 Safety Information W Warning 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.
Infrared Thermometers Symbols and Markings 3 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. Symbols Symbol Explanation X Hazardous voltage. Risk of electrical shock.
566/568 Users Manual 4 Features The thermometers include: • Single-spot laser sighting • Infrared and thermocouple temperature display • 12 or 24 hour clock • Celsius or Fahrenheit temperature.
Infrared Thermometers Menu Overview 5 Menu Overview There are many settings that can be easi ly 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.
566/568 Users Manual 6 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.
Infrared Thermometers Menu Overview 7 • 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.
566/568 Users Manual 8 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 em issivity setting. Note Min, Max, Avg, and Differential readi ngs are saved as part of the saved data when either Min/Max or Avg/Dif mode is enabled.
Infrared Thermometers Menu Overview 9 Setup From the Setup menu, the backlight, time and da te, 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.
566/568 Users Manual 10 10. Press the Next softkey to move through each parameter. 11. Press the Done softkey when finished. The display reverts to the beginning of the Time/Date menu. Language To change the displayed language: 1. From the main menu, press the Menu softkey until Setup appears as the left softkey function.
Infrared Thermometers How the Thermom eters Work 11 How the Thermometers Work Infrared thermometers measure the surface te mperatu re of an object. The thermometer’s optics sense emitted, reflected, and transmitte d energy, which is collected and focused onto a detector.
566/568 Users Manual 12 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 13 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 rela tionship between distance and spot size (D:S) for each unit is shown in Figure 5.
566/568 Users Manual 14 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). Ye s N o eyl05.eps Figure 6. Field of Vie w Emissivity Emissivity describes the energy-emitting characteristics of materials.
Infrared Thermometers Operating the Thermometer 15 Storing Data The 566 thermometer can store up to 20 data records. The 568 thermometer can store up to 99 data records.
566/568 Users Manual 16 External Contact Probe XW 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 7).
Infrared Thermometers Maintenance 17 Maintenance Battery Charge Use the battery charge symbols to gauge th e approximate level of charge left on the batteries. Notes When in low battery mode, the therm ometer does not store values. “Err” appears on the display if attempted.
566/568 Users Manual 18 Cleaning the Lens Blow off loose particles using clean compr essed 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. W Caution To avoid damaging the thermometers, do NOT submerge them in water.
