The PM53A is the essential shirt-pocket size meter. Only 3/8" thick and less than 3 oz in weight, this meter offers full functionality with ac and dc voltage to 450 V, resistance to 6 Megohm, capacitance to 100 µF, frequency to 30 kHz and continuity w/beeper. It also offers VolTect, a built-in, non-contact voltage detector for ac voltages.  Another key feature is AutoTect,™which automatically selects ac voltage, dc voltage or resistance measurement based on the test point to which the leads are connected.  Fully auto ranging, this meter offers seven different measurement functions plus features that are usually found in much more expensive and larger meters.  The digital display is oversized with large digits and unit icons in the display.  In spite of its size, this meter is fully safety rated to CAT III300 V, CAT II 450 V and is UL listed.
