Recording process
When you press the [REC] key, the data recording operation starts. Howev-
er, if the trigger function (described later) is used, recording may not begin
right away. In such a case, actual recording will only start when the trigger
conditions are met, or in other words when a trigger event occurs.
Recording stops when the amount of data corresponding to the recording time
has been recorded. If repeat trigger is selected, the recording condition is not
terminated at this point. Rather, the unit goes into trigger standby mode and
recording begins again at the next trigger event.
Even before the amount of data corresponding to the recording time has
been recorded, recording can be stopped by pressing the [STOP] key. It will
also stop when the SD memory card becomes full. Data recorded up to that
point will be stored.
Setting the recording time
The recording time can be set to 1 s to 59 s (seconds), 1 m to 59 m (minutes),
1 h to 24 h (hours), and a “Manual” setting is also available. When “Manual”
is selected, recording continues until the [STOP] key is pressed. Regardless
of the recording time setting, when there is no more room on the SD memory
card to store data (remaining recording time is about 10 seconds), recording
stops. Recording to one fi le is also limited to a maximum of 1000 hours.
When this limit is reached, the fi le is closed.
