a
Measurement data acquired by the Memory HiLogger can be saved to a CF
card or USB flash drive. (p.93)
The CF card is treated as Drive A:, while the USB flash drive is treated as
Drive B:. There are three save methods: [Auto Save], which saves data auto-
matically at the time of measurement; [Select & Save], which allows data to be
saved after measurement; and [Quick Save].
Refer to 6.3, "Saving Data" (p. 96)
for details.
When saving data, a folder named HIOKI_LR8431 is created, and files are
stored in the folder as follows.
*1. Save waveform data in binary format if you intend to view it later in the HiLogger or on a
computer with the supplied Logger Utility program. Waveform data and some measure-
ment-related settings data are saved.

To save a waveform partially, specify a period by using A/B cursors before saving (p.86).
*2. BMP Format: This is a standard Windows graphics format. These files can be handled
by many graphics programs.
*3. Appendix 2, "File Naming" (p. A7)
*4. Date (YY-MM-DD) folders are automatically created inside the DATA folder.
*5. When opening a CSV file in a spreadsheet 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 selected on the [System]
screen, the file extension will be .TXT rather than .CSV.
