The Megger DCM330 Fork Multimeter is a convenient, compact instrument designed to measure A.C. current flowing cables up to 200A, and perform the basic functions of a basic multimeter. With A.C. and D.C. voltage measurements up to 1000V plus resistance measurements up to 20 Mohms. The DCM330 also has a non-contact voltage detection facility and a continuity buzzer with diode check. The Megger DCM330 Fork Multimeter is a truly versatile compact test instrument which eliminates the need for a separate multimeter and clampmeter.

The open-jaw design of the Megger DCM330 Open Jaw Clamp Meter enable simple and fast measurements to be made on single conductors up to 16mm diameter. 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 DCM 330 Fork Multimeter is auto-ranging on all ranges. Voltage detection function on the Megger DCM330 Fork Multimeter 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 meter head. AC current measurement and the non-contact voltage sensor do not need the test leads; all other measuring functions will require their use.

The tough body provides easy and comfortable grip, providing durability while stored in a tool box or pocket. The Megger DCM330 Fork Multimeter is designed to withstand a 1.22m (4 feet) drop without damage.
