Description Functions low battery indication; auto power-off; data hold function; switching button from °C to °F; measurement of maximum, minimum. When choosing an infrared thermometer, consider D:S (distance to spot). Example - In this case we have a gun with 10:1 D:S, which means that if we measure an object at 10m distance, the spot that will measure the thermometer will be 1m, the instrument will give us an average value of the temperature of the measured spot.
