DESCRIPTION
The Megger DCM330 Fork Multimeter is a convenient,
compact instrument designed to measure ac current
up to 200 A, and perform the basic functions of a basic
multimeter.
With ac and dc voltage measurements up to 1000 V and resistance
, a non-contact voltage detection
measurements up to 20 M
facility and a continuity buzzer with diode check, the Megger
DCM330 is a truly versatile instrument. All of these features
combined into a single compactinstrument eliminate the
need for separate multimeter and clampmeter
The large central range knob enables ambidextrous singlehanded use, and the separate voltage/resistance test leads can
be disconnected when not in use.
The open-jaw design of the clampmeter enable simple and
fast measurements to be made on single conductors up to
16mm diameter. With no moving clamp parts, the Megger
DCM330 is not susceptible to dirt, grit or moisture around the
cable, so is equally ideal for use in dirty trenches or tr
or clean laboratory conditions. It provides average responding
RMS values, and with the conductor(s) positioned centrally
and squarely within the jaws, achieves readings of better than
3% accuracy.
The Megger DCM330 is auto-ranging on all ranges. Current
measurement and the non-contact voltage sensor do not
need the test leads; all other functions will require their use.
The voltage detection function can identif
of live AC voltages from 50 V to 1000 V at 50 to 500 Hz.

It is operational on any range including OFF. Voltage is
capacitively detected, signalled by a tone sounding and the
illumination of a red LED situated below the clamp head.
The Megger DCM330 is powered by 2 x AAA cells providing
250 hours of operation, and has an auto-off feature that
activates after approximately 10 minutes.
The tough body provides easy and comfortable grip,
providing durability while stored in a tool box or pocket. The
DCM330 is designed to withstand a 1.22m (4 feet) drop without damage.

APPLICATIONS
The DCM330 is suitable for use anywhere where there is a
requirement to measure ac current in single unshielded
onductors less than 16mm diameter, or ac/dc voltages up
c
o 1000 V, or resistances up to 20 MΩ.
t
ypical applications include domestic and industrial wiring
T
installation fault-finding, basic load analysis, equipment
commissioning and maintenance, machinery installations,
etc.
Note: The non-contact Voltfinder function is intended to
identify live cables within the jaws, and is not suitable for
use on shielded conductors such as armoured cable or
those within or behind metallic or conductive panels, in
metal conduit, etc.
