Description

CDM-330C2 Vector Multimeter

The CDM-330C2 Vector Multimeter is a compact, multifunction electrical measuring instrument designed to measure and analyze electrical parameters in low-voltage equipment. It measures AC voltage, current, phase angle, frequency, active and reactive power, power factor, and DC voltage, combining multiple measurement functions in a single device.

The CDM-330C2 supports simultaneous display of electrical parameters, waveform and vector visualization, and harmonic analysis of voltage and current from the 2nd to the 15th order. These functions allow users to examine electrical measurements and signal characteristics both numerically and graphically.

Optional accessories and modules extend its measurement capabilities to three-phase current, DC current, voltage-to-voltage phase measurement, timing functions, and data printing. This modular configuration allows the instrument to be equipped according to specific measurement requirements.
