PM3000A Measurement Summary
All measurements made digitally - No analogue error Stable over time Quick to calibrate
Accuracy maintained with wide range of input signal level and frequency: 0.05% Basic - 600V rms, 30A rms, DC to 1MHz
Single input shunt technology, accurate with high reliability.
Specification maintained with distorted power waveform.
DFT (not FFT) harmonic analysis system
Sample by sample calculation across 3 phases allows neutral calculation.
Useful additional functions like Inrush Current, Distortion and a.c. Impedance
Easy to use, all main power parameters available at push of button.
Non volatile memory to save any complicated front panel setup configuration.
Single phase, three phase and independent channel operation.
Fast computation for ‘real time’ feel
Many special modes: PWM Motor drive, Ballast, IEC testing etc.
Application specific software available, VPAS, (PM3000A) VPAS Lite (PM100), IEC1000-3-2/3 for Windows (PM3000A)
