| External level trigger function |
Pre-trigger |
Set the recording time prior to the recording start
condition as mentioned above. Setting zero seconds is
equivalent to no (with not-delete) pre-trigger function |
| Level trigger |
Set the level trigger threshold of designated channel.
When the analog input signal exceeds the threshold level,
the recording begins. |
| Record start condition |
Analog level |
Choice one of 1Channel to 4Channel. |
| A trigger direction against the threshold level. UP(default) / DOWN |
| Set the level trigger threshold [example : +50% ] |
| The recording time prior to the recording start condition [0 to 999 sec] |
| External trigger |
When the START/STOP signal at the SYNC IN connector on the
rear panel is changed from L level to H level, the recording stops |
| Manual operation |
It is started with an operation button |
