5.5 Optimizing recorded data (defragmenting)
If data have been recorded and deleted repeatedly, it is possible that some
memory areas are not used, resulting in a reduction of memory capacity. In
this case, it is recommended to optimize the memory and thus make these
memory areas usable again.
During deletion of the memory, a progress
indication appears. If automatic data logging was
active when the “Delete” function was started, it is
ended. The instrument is “ready to measure” (REC
blinks in the display).
Do not press any key as long as deleting is in
progress.
When the deleting procedure is finished, the
instrument returns to normal display.
h In normal display, press the MENU/POWER key
and then the SET key.
The memory screen (Fn1) is displayed.
h Press the MENU/POWER key five times until
you reach the “Defrag” function.
