Model 831 Manual Run Modes Without Measurement History 6-7
Daily Auto-Store
When Daily Auto-Store is set to
“Never”, as shown in FIGURE 6-3,
the Continuous Run mode is
essentially the same as the Manual
Run mode, with the exception that in
Continuous it automatically begins
running, thus measuring
continuously even when interrupted.
Daily Auto-Store permits the automatic storage of daily
measurement reports for 24-hour time periods, beginning at
a user-specified time. Each report can be configured to
represent the complete 24-hour time period or to include
data corresponding to equally-separated time periods within
the 24-hours.
Highlight the Daily Auto-Store field and press
5 to obtain
the menu shown in FIGURE 6-4.

When using Continuous run mode,
data files are stored in the following
format, regardless of what is
specified in the General setup tab:
yymmdd00.LD0, where yymmdd is
the date the measurement was
started.
Use the 2 and 8 arrow keys to select the desired
number of measurements per day and press
5.
When any option other than “Never” is selected, a Time data
field will appear as shown in FIGURE 6-5 to define the start
time for the 24-hour time period to be used for the report.

Highlight each data field, press
5 and use the arrow keys
to set the parameters as desired. Press
5 again to complete
the selection.
Effect of a Noise Event
If a noise event, described in Chapter 13 "Event History" on
page 13-1, occurs during the daily autostore, the storage
operation is delayed. This delay would be implemented
whether the status is Triggered or Valid. The autostore
would be processed one minute past the normal autostore
time or right when the event ends (not including the
continuation process), whichever comes first.
