Description
The Amprobe PM51A, a shirt-pocket sized meter is only 3/8″ thick and weighs less than 3 oz. With full functionality offering AC and DC voltage to 600 V, resistance to 40 megohm, capacitance to 3000 μF, frequency to 1 MHz, continuity with beeper, and diode test.
Fully auto-ranging, this meter offers seven different measurement functions with 27 full ranges of measurement. The digital display is oversized with large digits and annunciators. In spite of its size, this meter is fully safety rated to CAT III 300 V, CAT II 600 V and is UL listed. No other meter offers this small size with such performance and high safety ratings.
