Chapter 5 Programming
5.7.3 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.
5.7.3.1 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”.
5.7.3.1.1 Fill to End
The unit will record to disk until the disk is full, and then it will shut the recording off.
5.7.3.1.2 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.
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. 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.
5.7.3.2 Instantaneous/Average Mode
The instantaneous or average method of recording can be made to apply to all points simultaneously, or it
can be set independently for each individual point. Use “Inst/Avg All” to set a single mode for all points, or
“Inst/Avg Indiv.” to set the mode individually for each point.
5.7.3.2.1 Inst/Avg All
The user has the option to select Instantaneous or Average which is applied to all points simultaneously.
Use the UP (
↑) or DOWN (↓) Arrow Keys to highlight “Inst/Avg All” on the Record Mode menu. The
current Record mode will appear highlighted. To change it, use the UP ( ↑) or DOWN (↓) Arrow Keys to
highlight either “Instantaneous” or “Average” as required and press ENTER to activate. Press EXIT to
return to the Record Setup Program menu.
