Note on phase
settings
Phase settings depend upon the wiring configuration or circuit type selected under
Setup New Circuit. For example, for wye circuits, Line-Neutral (L-N), Neutral-Ground
(N-G), and Line-Line (L-L) voltage limits can be set. For delta circuits, only L-L limits
can be set.

STEP 4: Select how you want to
specify the number of waveform
cycles to record before (Pre-) and
after (Post-) the trigger cycle.
• Enable
Use Default
if you
want to use the default
waveform trigger cycle counts
for transient events (Pre-trigger
cycles = 1, Post-trigger cycles
= 2).
• Enable
Set the same as RMS
Variation Wave Snapshot
Pre/Post Setting if you want to
use the same waveform trigger
cycle counts to capture
transient events and rms events
(Pre-trigger cycles = 2, Post-
trigger cycles = 2). See Step 3
of the Procedure to record rms
variation on page 6-11.
• Press
Finish
to accept the new
waveform capture cycle
settings. The screen will return
to Advanced Options menu.
• Press Prev to return to the rms
distortion waveshape screen.
• Press
Cancel
to retain previous
cycle counts and return to
Advanced Options menu.
