Model 831 Manual Combined Sound Recordings 16-19
Snapshot Time
Note that the maximum value of
Snapshot Time that can be entered is
9,999 seconds. However, the
maximum time of an actual
recording may be limited by the
sample rate and the memory size.
The Snapshot Time is the duration of each Measurement
Sound Recording. To enter the Snapshot Time, highlight the
Snapshot data field and press
5. This will produce a cursor
which can be moved left and right to different digit positions
in the data field using the
4 and 6 keys.

Recording Status Icon
When a recording is in progress, the Recording Status Icon,
shown greyed out in Figure 16-6, will become active.
Combined Sound Recordings
Only one sound recording can be made at a time. As a result,
should a sound recording be initiated, manually or
automatically, while a sound recording is already in
progress, the original sound recording will continue.
However, should the parameters for the second recording
call for that recording to be concluded at a time later than
that defined by the parameters of the first recording, the
original recording would continue until the parameters of the
second recording are satisfied.
More generally, when a sound recording is initiated, a
counter is begun to define when that recording should stop.
If during that recording one or more additional recordings
are initiated, a counter will be begun for each, even though
the same recording is continued rather than a series of
separate recordings. The original recording will then stop
when the counters of all recordings have counted down to
zero, indicating that the time interval of that recording
encompasses all the data which would have been recorded
by those separate recordings.
