PM53A Pocket Multimeter |
|
|
|
|
This meter is the
essential shirt pocketsize 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 to100 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 autoranging, 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. Includes a silicone protective holster, attached
test leads, battery and manual.
