The compact commercial DMM with AutoTect™ and VolTect™
This meter is the essential shirtpock-
et 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 detec-
tor 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 III 300 V, CAT II
450 V and is UL approved. Includes a
silicone protective holster, attached
test leads, battery and manual.

AutoTect™ feature directs the meter to know if it is measuring AC
volts, DC volts or resistance with no user interface required
The AutoTect™ feature has lower input impedance which zeros
out ghost voltages
Measures capacitance, frequency, continuity with beeper plus
includes VolTect,™ a built-in, noncontact voltage detector
