Make settings for the sampling frequency, analog-digital
conversion bit depth, number of recording channels,
voice memo activation and input amplification.

In order to record measurements with greater preci-
sion, however, we recommend letting the system
warm-up for at least 10 minutes and then manually
calibrating it before beginning measurement.

7-4. Set triggers
In addition to manually starting and stopping recording,
you can also set the system to start and stop recording
using triggers and intervals. See “7-4-2. Interval record-
ing” on page 32 and “12. TRIGGER settings” on page
58 for details about settings.
ATTENTION
When using triggers and intervals to start recording
automatically, put the unit into a record ready state. The
unit will not detect triggers if just in a stopped state.

Recording time
For trigger recording, you can set a combination of
recording starting conditions (level trigger, external
trigger or timeout) and recording stopping conditions
(level trigger, external trigger or recording time).
Recording starting conditions
Level trigger
Use a level change for the set channel as a trigger.
External trigger
Recording starts when the input through the external
trigger input connector (TRIG IN) becomes the L level
(0.6 V or less).
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.
