This unique measuring device features a complete set of functions in a compact design, measuring only 4 mm in depth and weighing 90 g, offering optimal portability in a pocket-sized format. The PM55A provides unrestricted automatic range selection and an oversized, easy-to-read digital display. With the AutoTect function, the measuring device can detect and display measurements of AC voltage, DC voltage, and resistance. The PM55A includes VolTect, a built-in non-contact voltage tester for AC voltage. Despite its small size, the device meets UL safety standards according to CAT III and is "UL listed." The Amprobe PM55A precision measuring instrument includes measurement additions such as capacitance, frequency, DC microamperes, and safety features like voltage spikes up to 4 kV and overload protection up to 600 V.
