SIREC D Manual
Programming
4.7.3 Record Mode. There are three
options “Fill Mode”, “Inst/Avg All” and Inst/Avg
Indiv”. The “Fill Mode” determines whether files are
to be recorded to fill the disk and stop, or recycle,
deleting the oldest data and replacing it with new.
The Instantaneous/Average options determine
whether data will be averaged over the record
interval or whether the latest data only is stored. If
you are using one of the intrinsic functions of the
unit, for example Peak Values, you must set the
sample mode to instantaneous or you will “average”
your “peaks” if you have a slow sample storage rate.
A. Fill Mode - Use the Up (↑) or DOWN (↓)
Arrow Keys to highlight “Fill Mode” from the Record
Mode Menu. There are two options available, “Fill to
End” and “Cycle Data”.
1. Fill to End - The unit will record to disk until the
disk is full, and then it will shut the recording off.
2. Cycle Data - The unit will continue to record to
disk until the disk is almost full and then it will start
to write over the earliest data a block at a time
(about 500 samples at a time). The disk will always
contain the most current data, and the oldest
data will be lost. All points respect the integrity
of data for other points, each point will only replace
it’s own data.
NOTE
Set the disk full threshold to 100% when
running in the cyclic mode to prevent the
disk full alarm from activating.
3. Programming - The following steps guide you
in programming Fill Mode:
a. To program the Fill Mode use the UP (↑) or
DOWN (↓) Arrow Keys to highlight “Fill Mode”
on the menu and press ENTER. The current
Record mode will appear highlighted.
b. To change it, use the UP (↑) or DOWN (↓)
Arrow Keys to highlight either “Fill to End” or
“Cycle Data” as required and press ENTER to
activate. Press EXIT to return to the Record
Setup Program menu.
