Table
During active recording TABLE view is available (see section 3.14 for instructions how to start recording),
by cycling function key F4 (METER –TREND - TABLE). Signalling events can be here observed as required
by standard IEC 61000-4-30. For each signalling event instrument capture waveform which can be
observed in PowerView.
