input and output.
o
Calibration is conducted automatically when this system’s power
is turned on.
o
In order to record measurements with greater precision, however,
we recommend manually calibrating the system after letting it
warm-up for at least 10 minutes before beginning recording.

8-4. Setting triggers
In addition to manually starting and stopping recording, you can
also set the system to start and stop recording using triggers and
intervals. For details about how to make settings, see page 67.

Recording stops
For trigger recording, you can set a combination of a starting trigger
(level, external or timeout) and a stopping trigger (level or external).
Recording starting conditions
Level trigger
Use a level change for the set channel as a trigger.
External trigger
When the input through the EXT TRIGGER IN connector becomes
the L level (0.4 V or less), recording starts. If the L level has already
been reached, when the system becomes record ready, recording
starts immediately.
Timeout
If the conditions set to start recording are not met within a specified
time, recording will be forced to start automatically.
Pre trigger
By default, the system saves data from the time between when a
recording starting condition occurs and when a recording stopping
condition occurs.
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
When the input through the EXT TRIGGER IN connector becomes
the H level (open or 2 V or more), recording stops.
