| Amprobe PM55A Digital Multimeter Description: |
Amprobe PM55A Digital Multimeter
offers VolTect,â„¢ a built-in,
non-contact voltage detector for
ac voltages. Another key feature is AutoTect,â„¢
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. It includes a silicone protective
holster, deluxe carrying case,
attached test leads, battery and
manual.

| Amprobe PM55A Digital Multimeter Characteristics: |
| |
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

Measures ac/dc current,
capacitance, frequency,
continuity with beeper
plus includes Voltect,™
a built-in, non-contact
voltage detector
