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. The thermometers also support contact-temperature measuremen[...]

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-battery indicator appears. • Do not use the t[...]

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. The unit’s electronics translate the signal into a temperature reading whi[...]

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 rela tionship between distance and spot size (D:S) for each unit is shown in Figure 5. The spot sizes indicate 90 % encircled energy. 56 8 eyl0[...]

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. Most organic 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. The following in formation is stored in each record: • Record number • IR and probe temperature in ° F or ° C • Date/Time • Emissivity • Max/Min/Avg/Dif Temperature (if[...]

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). Wi[...]

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. J Batteries are at 5 %. Before taking further readings, the batteries m[...]
