5.2.4. INSTANTANEOUS INRUSH CURRENT
PEAK mode displays the envelopes and waveforms of the inrush current capture. The PEAK display of an inrush current capture
provides two possible representations:
■
envelope
■
waveform
The change from one of these representations to the other is automatic, as a function of the zoom level. If the zoom in is high
enough, the representation is of the "waveform" type.
The display depends on the type of display filter:
4V: displays the 4 voltages during the inrush current capture for set-ups with neutral (for a waveform type display only).
3U: displays the 3 voltages during the inrush current capture for set-ups without neutral (for a waveform type display only).
4A: displays the 4 currents during the inrush current capture (for a waveform type display only).
L1, L2 or L3: display the voltage and current of phases 1, 2, and 3, respectively (only for set-ups with neutral and for a waveform
type display).
N: displays the neutral current and neutral voltage during the inrush current capture (for a waveform type display only).
V1, V2, V3: displays the 3 voltages during the inrush current capture for set-ups with neutral (for an envelope type display only).
U1, U2, U3: displays the 3 voltages during the inrush current capture for set-ups without neutral (for an envelope type display only).
A1, A2, A3: displays the 3 currents during the inrush current capture (for an envelope type display only).
Below are three examples of display.

Location of the zone displayed in
MAX |PEAK|: maximum
instantaneous absolute value of
the inrush current capture.
Scale of values in amperes.
t: relative time position of the cursor
(t=0 corresponds to the start of the
inrush current capture).
