10.11 Timer Trigger Function
────────────────────────────────────────────────────
End time
Recording length
Time interval
MEM, FFT
REC and RMS
Note on use for the timer trigger
(1) Set the present time on the SYSTEM screen first, then set the timer trigger.
(2) Set the start time and end time to a point after the pressing of the
START
key.
(3) When the trigger mode is set to SINGLE, only one trigger event is valid for
the start time. The settings for time interval and end time are invalid (when
timer trigger only is ON).
(4) To perform recording at regular intervals, establish the following settings.
Trigger mode: repeat. Other trigger sources: all OFF
Between end of recording and standby, triggers are invalid while processing
is taking place (auto save, auto print, waveform display, calculation, etc.)
and therefore data may not be recorded at regular intervals with some
measurement setting.
(5) When trigger sources have been linked with OR
All trigger sources are valid. Therefore triggering may occur even before the
start time, and trigger standby and measurement may continue even after the
stop time.
(6) When trigger sources have been linked with AND
・Trigger standby is enabled at the measurement start time and at each
interval, and triggering will occur when all trigger conditions other than
timer trigger are met simultaneously.
・Setting the interval to 0 can be made active for the preset time interval only.
・When the recording length (recording time) is longer than the time interval:
1. Timer trigger, which is determined from the time interval during
recording, is disabled.
2. End time
MEM, FFT: Retrieve measured data equivalent to the recording length
and discontinue measurement.
REC, RMS: Stop retrieving measured data at the set stop time.
