Enable the trigger function (set to On), select recording start/stop timing, and set trigger criteria.
Make these settings on the
[Trig & Alm] screen.
See:
"Key Setting Procedure" (p .130)
Selecting Triggering Criteria (Trigger Source)
If trigger settings have been made on the [CH] screen, skip steps 1 and
2. (The settings in steps 1 and 2 are interlinked with those on the [CH]
screen.)
1
Select the [CH] or [Trig&Alm] Screen.
2
Enable triggering [On] .
3
Select measurement start/stop timing.
(Start and stop triggers can be set for each channel
independently.)
4
Select trigger combining logic.
Interval triggers are not included in the above trigger
criteria, and start trigger events will occur when crite-
ria set with an interval trigger are satisfied.
See:
"Applying Trigger at Fixed Time Interval (Interval
Trigger)" (p .138)

trigger criteria are already met when

measurement starts.
Before triggering can occur, trigger

criteria must first become invalid once.
