7. Recording
When a pre-trigger interval is set, data is recorded
before a recording starting condition occurs, but
only after the system is made record ready.
o
You cannot record voice memos during this time.
Recording stopping conditions
Level trigger
Use a level change for the set channel as a trigger.
External trigger
Recording stops when the input through the exter-
nal trigger input connector (TRIG IN) becomes the H
level (open or 3 V or more).
Recording time
Recording continues only for the set amount of time.
Post-trigger
Even after one of the above recording stopping con-
ditions is met, recording will continue for the set
amount of time.
o
When recording is stopped manually, however,
post-trigger recording will not occur.

With interval recording, when the number of repetitions
is set to 1, recording will start at the set time and stop
after the set recording time has elapsed.

When the number of repetitions is set to 2 or more,
recording will start at the set time and stop after the
set recording time has elapsed. Then, the system will
become record ready and start recording again after the
set interval. After this process has repeated to record the
set number of repetitions, recording will stop.
If the number of repetitions is set to 0, interval recording
will repeat until the recording media is full, or recording
is stopped manually.
Start time
Recording starts at the set time.
ATTENTION
If the set time has already passed when the unit is made
record ready, recording will not start.
The unit might take some time to become record ready
if, for example, there are already many recorded files.
Considering this, set the start time with sufficient spare
time.
Recording time
Recording continues for the set amount of time.
Interval time
If the number of repetitions is set to 2 or more
recordings, this is the amount of time that the sys-
tem stays in a record ready state from the time one
recording ends until the next recording starts.
Repetitions
Sets the number of repetitions. When set to 0, interval
recording will repeat until the recording media is full
or recording is stopped manually.
o
When set to 0, if recording is repeated until the
recording media becomes full, the recorded data
for the last recording might not be as long as the
recording time setting.
