The 2505 Digital AC Meter is a 3 phase, 4 wire meter offering ?0.25% accuracy for the measurement of true rms voltage, current and power through the 3 wattmeter method. The instrument has excellent stability and noise characteristics and is ideally suited for the measurement of both balanced and unbalanced 3 phase, 4 wire circuits and for both sinusoidal and complex waveforms. It may also be used in 3 phase, 3 wire and single phase circuits with no deterioration of performance.
