1 Infrared Thermometers Introduction The 566 and 568 Infrared Thermometers (“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. The thermometers als...

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. • Replace the batteries as soon as the low-b...

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. W Risk of danger. Important information....

Infrared Thermometers How the Thermometers Work 11 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...

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. Locating a Hot or Cold Spot

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 relationship between distance and spot size (D:S) for each unit is shown in Figure 5. The spo...

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). Yes N o eyl05.eps Figure 6. Field of View Emissivity Emissivity describes the energy-emitting charact...

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. The following information is stored in each record: • Record number • IR and probe temperature in ° F or ° C • Date/Time • Emissiv...

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 locate...

Infrared Thermometers Maintenance 17 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 %. Bef...

566/568 Users Manual 18 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. W Caution To avoid damaging the thermometers, do NOT submerge them in ...
