568 EX Users Manual Product Operation Temperature Measurement To measure temperature, point the Product at an object and pull the trigger. You can use the laser pointer to help aiming. You can also insert the KTC probe for contact measurement. Be sure to consider distance-to-spot size ratio and field of view (see “Distance and Spot Size” and “Field of View”). Note The laser is used for aiming purposes only and is not related to temperature measurement.
Infrared Thermometer Product Operation Distance and Spot Size As the distance (D) from the object under measurement increases, the spot size (S) of the area measured by the Product becomes larger. The relationship between distance and spot size (D:S) is shown in Figure 5. The spot sizes indicate 90 % encircled energy. hhe06a.eps Figure 5.
568 EX Users Manual Field of View When making measurements, make sure that the target is larger than the Product spot size. The smaller the target, the closer you should be to it (see Figure 6). For accurate measurement, it is strongly recommended that the target size is at least twice as large as the spot size. Yes No eyl05.eps Figure 6.
Infrared Thermometer Product Operation HOLD After the trigger is released, the display retains its last infrared measurement for 20 seconds. At the same time, HOLD shows on the display. With the probe inserted, the contact Product stays on. To freeze the infrared temperature when a probe is not inserted, release the trigger until HOLD shows on the display. hhe03.eps Figure 7.
568 EX Users Manual External Contact Probe The Product has a bead KTC probe. The probe attaches to the Product via the probe input located on the top of the Product (see Figure 7). With the probe installed, the probe symbol () shows on the display. The probe can be used simultaneously when the Product is making non-contact measurements. The probe measurements are shown below the non-contact measurements. The Product stays on when a probe is inserted.
