If [Off] is selected, skip steps 2 to 5.
If [Calc (post meas
.)] is selected, skip steps 4 and 5.
2 Specify the waveform file name (if needed).
See: "3.7 Entering Titles and Comments (as needed)"
(p. 71)
If left blank, file names are cre
ated automatically.
See: "Appendix 3 File Naming" (p. A8)
3 Select the removable storage priority (CF card or

4 Select whether to delete while saving.
Select the desired operation when removable storage be-
comes full while saving.
5 Select whether to save data into multiple files
(“Split Save”).
Select single (per measurement) or multiple (timed) file
creation.
6 Press START to start measuring.
After measurement, the data is automatically saved to re-
movable storage (p. 121).


Saving ends when the removable storage is
nearly full.
On When the free capacity of the removable stor-
age reaches a certain minimum size, wave-
form files are deleted, oldest f
irst. If deletion is
not possible, saving stops. Delete while saving
does not apply to numerical calculation files.
Setting options: (  : default setting)


Creates a single file per measurement.
On Specify the save timing (split time). (Figure at
right) A new data file is created for each split
time (span).
Ref
Time
Specify the reference time (Ref Time) and split
time (Split Length). (Figure at right) A new file
is created for each split time (span), starting

[Split Length]:1, 2, 5, 10, 15,
20, 30 minutes, 1, 2, 3, 4, 6, 8,
12 hours, 1 day
Also set the
[Split Length].

Minutes (0 to 59)
Before measurement starts,
"Sync fixed time" is displayed
until the next measurement
time synchronizes with the ref-
erence time.
The horizontal axis setting is lim-
ited when auto saving waveforms
(p. 68).

Before starting to measure,
confirm that Auto Save is
configured correctly, and
that the removable storage
is properly installed.
