Infrared Thermometers 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.
56x Users Manual Safety Information A Warning identifies conditions and actions that pose hazard(s) to the user; A Caution identifies conditions and procedures that could cause Product damage, equipment under test damage, or permanent loss of data. Symbols used on the Product and in this manual are explained in Table 1 and Figures 1 and 2. *WWarning To prevent eye damage and personal injury: 2 • Read all safety Information before you use the Product.
Infrared Thermometers Safety Information WCaution To avoid damaging the thermometer or the equipment under test, protect them from the following: • EMF (electro-magnetic fields) from arc welders, induction heaters, etc. • Static electricity • Thermal shock (caused by large or abrupt ambient temperature changes- for highest accuracy, allow 30 minutes for thermometer to stabilize before use). Table 1. Symbols Symbol X W * P °C °F M Explanation Hazardous voltage. Risk of electrical shock.

56x Users Manual 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.
Infrared Thermometers 566/568 Display 566/568 Display The 566/568 thermometers display can show data in the following languages: • English • Spanish • French • German • Portuguese • Japanese • Simplified Chinese To change the displayed language, refer to “Setup”. 566/568 Menu Overview There are many settings that can be easily changed by using the menu. Figure 4 shows the LCD and menu interface. Selecting the Menu softkey advances the menu to the next level.

56x Users Manual 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. When the alarm level is reached, an alarm will sound and the display will flash orange and white. To set either the high or low alarm: 1. Press the Menu softkey until Alarm appears as the right softkey function. 2.
Infrared Thermometers 566/568 Display 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.
56x Users Manual To change the date on the thermometer: 1. From the main menu, press the Menu softkey until Setup appears as the left softkey function. 2. Press the Setup softkey. 3. Press the down arrow softkey to select Time/Date. 4. Press the Enter softkey. 5. Press the Date softkey. 6. Select the date format: Day/Month/Year (dmy) or Month/Day/Year (mdy). 7. Use the up and down softkeys to change the selected parameter. 8.
Infrared Thermometers Buttons and Connector Deleting Individual Data Records To delete individual records, press the View softkey and then use the down and up arrow softkeys to access the desired record. Once the desired record is shown, press the Yes softkey to delete the record. To cancel data deletion, pull the trigger. Buttons and Connector Table 5 shows the buttons and connector used for the thermometers. Table 5.
56x Users Manual 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 Transmitted energy Emitted Energy eyl002f.eps Figure 5.
Infrared Thermometers Operating the Thermometer 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). eyl07.eps Figure 6.
56x Users Manual 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. D:S=12:1 561 75 mm @ 900 mm 132 mm @ 1500 mm S 38 mm @ 300 mm 1.5 " @ 12 " 3"@ 36 " 5.3 " @ 60 " D 568 eyl06a.eps Figure 7.
Infrared Thermometers Operating the Thermometer 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). Yes No eyl05.eps Figure 8. 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.
56x Users Manual 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”.
Infrared Thermometers External Contact Probe 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 9). With the probe installed, the probe symbol () appears on the display.
56x Users Manual 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. Batteries are at 5 %. Before taking further readings, the batteries must be changed. Changing the Batteries WWarning Batteries contain hazardous chemicals that can cause burns or explode.
Infrared Thermometers User Replaceable Parts and Accessories AA (+) eyl04.eps Figure 10. Battery Replacement 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.
