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.

No
Signalling event number
L
Phases on which signalling event occurred
F
Flag indication
0
– none of intervals are flagged
1
– at least one of intervals inside recorded
signalling is flagged
Sig
Frequency on which signalling occurred, defined as
“Sign.
