The overall duration of a single fault recording comprises the total duration of the recording
criterion, the pre-trigger time and the post-trigger time. With the fault recording parameter, these
components can be individually set. The pre-trigger waveform recorded duration is configured via
the setting [RecT_PreFault]. The waveform recorded duration after the fault disappears is
configured via the setting [RecT_PostFault]. The maximum waveform recorded duration is
configured via the setting [MaxT_OneRec].

1. Pre-trigger recording time
Use the setting [RecT_PreFault] to set this time.
2. Pickup recording time
The pickup recording time cannot be set. It continues as long as any valid trigger condition, binary
or analog, persists.
3. Post-fault recording time
The recording time begins after all activated triggers are reset. Use the setting [RecT_PostFault] to
set this time.
4.Maximum recording time
Use the setting [MaxT_OneRec] to set this time. If the summation of wave recording duration is
larger than maximum recording time, the one recording time shall be equal to the setting
[MaxT_OneRec].
