You'll enjoy a multitude of valuable features with the Amprobe Pocket Size AutoRanging Multimeter.
Features & Applications:
The Amprobe PM55A is the ultimate shirt-pocket sized
meter. Only 3/8" thick and less than
3 oz in weight with full functionality
offering ac and dc voltage to 600 V,
ac and dc current to 2000 µA, resistance
to 6 Megohm, capacitance to
2000 µF, frequency to 30 kHz, diode
test 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
between ac voltage, dc voltage or
resistance measurement based on
the test point to which the leads are connected. Fully autoranging, this
meter offers nine 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 III
300 V, CAT II 600 V and is UL listed.
No other meter this small offers
such performance and high safety
ratings. Includes a silicone protective
holster, deluxe carrying case,
attached test leads, battery and
manual.
Features:
- Unique AutoTect™ feature directs the meter to know if it is measuring AC volts, DC volts or resistance with no user interface
- The AutoTect™ feature has lower input impedance, which zeros out ghost voltages
- High Input Impedance feature for measuring electronic control circuitry
- Measures ac/dc current, capacitance, frequency, continuity with beeper
- Includes Voltect,™ a built-in, non-contact AC voltage detector
- Complete user protection with full safety ratings of CAT III 300 V, CAT II 600 V and cULus listing
- Large oversize digital display
- Protective silicon holster included, attached test leads, battery, deluxe zippered carrying case and manual
- One-year No Hassle warranty
