Category

Tools

Statistical evaluation

Power quality statistics according to EN50160 and DISDIP tables like ITIC, CEBEMA, ANSI

Event strip

Dips, swells and interruptions are detected and stored in the event strip. Also any trigger which fires generates an event added to this strip.

Triggered recordings rms

Aggregation time is adjustable between 10 ms (1/2 cycle), 20 ms (1 cycle), 200 ms (10/12 cycles) or 3 sec (150/180 cycles).

Triggered recordings Mains signalling

Phases and N-conductor, Voltage and current

Triggered recordings Online mode

Variable refresh rate. This feature allows verification of instrument set up and delivers a quick overview of oscilloscope, transients and events.
