Frequently asked questions

Rotate the function switch to the 400AAC position, open the jaw, fully enclose only one conductor, and then read the current value in the display

The maximum voltage that can be measured is 600V DC/AC

Rotate the function switch to the IR position, select °F or °C, aim the infrared sensor at the surface to be measured, press the IRT button, and read the temperature in the display.

The IR thermometer has a distance ratio of 8:1, which means that the spot size is 1/8th the distance from the meter to the target.
