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. |
