CPU2 option – the co-processor board performs the simultaneous high-resolution sampling of voltage and current, allowing the cycle-by-cycle power analysis for 50/60 Hz lines.
VDROP option – sags & swells detection as per EN50160 standard on L-N voltages with half cycle resolution (10ms @ 50Hz). Pre-and Post-trigger logging (100 +100 half cycles RMS values).
VMAX option (EN50160 standard) – VDROP and Min/Avg/Max values calculation and recording with one cycle resolution (20ms @ 50 Hz). This function allows to record up to 10 parameters selected among voltage, current, power, PF and frequency.
Time – of – Use (TOU) programmable data recording.
WCAP option – advanced waveform capture function on currents and L-N voltages. The instrument can store up to 10 + 200 waveforms before and after a threshold overcome, with a resolution from 8 to 32 samples includes a second selectable function: Min/Avg/Max values recording.
Up to 10 programmable recordings with different start and stop time.
Import/export active, reactive and apparent power demand with programmable average time. The average period can be synchronized by a digital input.
