Recording Trends and Event Waveforms
Recording event waveforms
Waveforms observed in the approximately 200-ms aggregation period are recorded as event
waveforms.
Event waveform recording period
50 Hz: Waveform observed for a 10-cycle period
60 Hz: Waveform observed for a 12-cycle period
When an event occurs on a measured value obtained over an approximately 200-
ms aggregation period
Approx. 200 ms aggregation (50 Hz: 10 cycles, 60 Hz: 12 cycles)
SET UP, Record Settings screen: Recording Interval Settings

When an event is occurred on a measured value obtained a 1-cycle or half-cycle
Approx. 200 ms aggregation (50 Hz: 10 cycles, 60 Hz: 12 cycles)
SET UP, Record Settings screen: Recording Interval Settings
• On the SET UP, Event settings 2 screen, Event waveform recording time: “Before event occurs” setting
allows an immediately previous waveform with a length of a set time to be stored in addition to an event
waveform with a length of a 200-ms aggregation period observed at an event (p. 74).
Event waveform recording time: “Before event occurs”: OFF, 200 ms, 1 s
• On the SET UP, Event settings 2 screen, Event waveform recording time: “After event occurs” setting
allows an immediately previous waveform with a length of a set time to be stored in addition to an event
waveform with a length of a 200-ms aggregation period observed at an event. (p. 74).
Event waveform recording time: “After event occurs”: OFF, 200 ms, 400 ms, 1 s, 5 s, 10 s
