Digital Multimeter
The ultimate shirt-pocket DMM with frequency & capacitance
This shirt-pocket-sized meter is only
3/8” thick and weighs less than 3 oz.
With full functionality offering AC
and DC voltage to 600 V, resistance
to 40 Megohm, capacitance to 3000
μF, frequency to 1 MHz, continuity
w/beeper, and diode test.
Fully autoranging, this meter
offers seven different measurement
functions with 27 full ranges of
measurement. The digital display is
oversized with large digits and an-
nunciators. In spite of its size,
this meter is fully safety rated to
CAT III 300 V, CAT II 600 V and is UL
approved. No other meter offers this
small size with such performance
and high safety ratings.
