Chapter 6 Saving & Loading Data
Before measuring, configure saving on the [Setting] screen. Waveforms and
numerical calculation results can be saved automatically. Folders are created for
saved data according to data type, and files are automatically numbered (p.91).
For waveform data, folders named with the
current d
ate (YY-MM-DD) are cre-
ated automatically. Before starting to measure, confirm that Au
to Save is config-
ured correctly, and that the CF card or USB
flash drive is properly installed.

*1. Otherwise, make advanced settings as needed (p.46).
See: "When [Waveform(realtime)], [CSV(realtime)], [Waveform + Calc], [CSV
+ Calc] is selected" (p. 47)
*2.The [CSV (real time)] and [CSV + Calc] settings are not available when the
record interval is 10ms or 20ms. Also, when opening a CSV file in a spread-
sheet program, note that the number of rows that can be loaded at one time is
limited (p. A7). When an option other than [Separator: Comma] has been select-
ed on the [System] screen, the file extension will be .TXT rather than .CSV.
To save calculation results automatically, configure calculation settings before
starting measurement (p.113).
When saving waveforms automatically, horizontal axis display setting is re-
stricted when starting measurement, but can be freely adjusted for analysis af-
terwards (although 100, 200 and 500 ms horizontal axis settings are
automatically changed to 1 s when measurement starts, and cannot be rese-
lected while measuring).
Save methods:
