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 measurements up to 20 MΩ, a non-contact voltage detection facility and a continuity buzzer with diode check, the
Megger DCM330 is a truly versatile instrument. All of these features combined into a single compact instrument 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 enables 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 trunking; 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 identify the presence 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.
The display is a large 3½ digit LCD. In difficult or awkward locations, the display can be frozen with the "HOLD" function, removed from the cable under test and read independently.
