∗1: Save waveform data in binary format if you intend to view it later in the HiLogger or on a PC with
the supplied Logger Utility program. Waveform data and some measurement-related settings
data are saved.
To save a waveform partially, specify a period by using A/B cursors before saving (p. 92).
When the scaling function is set to enable, scaling information as well as raw data (non-converted
data) in binary format are saved. When the data saved in the storage devices is loaded, the con-
verted data will be displayed. The raw data can also be observed by resetting the scaling function
to OFF.
∗2: 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. A8).
∗3: BMP Format: This is a standard Windows
graphics programs.
∗4: Date (YY-MM-DD) folders are automatically created inside the DATA folder.
∗5: When saved manually. See "Appendix 3 File Naming" (p. A8) for file naming details.
*6: The TXT file extension is applied except when
screen.
∗7: When creating calculation-specific files, an underbar and a serial number (_n) is appended to the
file name, e.g., MEAS0001_1.CSV, MEAS0001_2.CSV, etc.
Depending on file size and CF card capacity, each folder can store over
1,000 files. However, the file screen display is limited to a maximum of
1,000 files. Also, as more files are created, more time is needed to start
and stop recording. We recommend setting measurement criteria so that
the number of saved files stays below 1,000 whenever possible.
