The Megger DCM2000P Power Clampmeter combines the functionality of power meter, oscilloscope, harmonics meter and data logger in one easy to use package. The design meets the requirements of BSEN 61010-1 600V Cat IV for supply side applications. A large backlit dot matrix LCD clearly displays waveforms, harmonics, chart trends and up to five parameters at a time. The DCM2000P can measure dc, ac, pulsed and mixed currents up to 2000 A, voltages up to 600 V, all power related parameters including energy consumption, frequency, crest factor, total harmonic distortion, distortion factor and ripple. It features auto ranging and auto-zeroing and has a built-in three-phase adapter for power measurements.

This battery-operated precision power meter can transmit both stored and live measurements to a PC running AVO PowerLog software for further analysis if required. The DCM2000P is ideally suited to measure mains power quality and applications in the development, installation, maintenance and repair of equipment and devices used in power electronics and power engineering. It simplifies the compensation of reactive power, even for complex waveforms with high harmonic distortion.

Data Logging
The DCM 2000P may be used to perform data logging to its internal non-volatile memory , or in real time to a serially connected PC running the optional PowerLog software. In PC mode data is continually sent to the PC and is not stored in the instruments memory. All the parameters shown on the display are logged. When internal logging is selected, up to 5000 readings may be stored, (2500 sets of two or 1000 sets of 5 parameters). The maximum logging period is the determined by the memory capacity and the battery life, (24hrs in this mode). A chart display screen is also available to show the variation of single parameter during the logging period.
