UT300 SERIES Non contact Infrared Thermometer Operating Manual P N 110401101601 Locating a Hot or Cold Spot To find a hot or cold spot aim the Thermometer outside the target area Then slowly scan across the area with an up and down motion until you located the hot or cold spot See Figure 5 a R SaL gt Distance and Spot Size As the distance D from the target being measured increases the spot size S of the area measured by the unit becomes larger The spot size indicates 90 encircled energy The maximum D S is obtained when the Thermometer is 1000mm 100 in form the target resulting in a spot size of 20mm 2 in Field of View Make sure that the target is larger than the spot size The smaller the target the closer you should be to it Suggested distance less than 75 of the theory value Introduction The Model UT300A and UT300B Infrared Thermometer hereafter the Thermometer can determine the surface temperature by measuring the amount of infrared energy radiated by the target s surface They have different distance to spot D S figure and different temperature range details see the contents The Thermometers are non contact infrared thermom eter with low consumption design so that they can be used for a longer time which can solve the frequently changing battery and low battery issues during measurement intelligent design can make measure ment easier and qui
