*1 When auto saving waveform data and calculation results, automatically generated serial
n
umbe
rs (up to eight digits) are appended to the specified file name. If no file name is
specified, AUTO is automatically entered.
(XXXX0001.MEM, XXX00001.MEM, XX000001.MEM, X0000001.MEM)
When auto numbering exceeds 9999, the file name characters are overwritten (right to
lef
t) un
til all eight digits are used for serial numbers.
(Example: WAVE9999.MEM, WAV10000.MEM, .. )
*2 When [Deleting] is enabled with auto save, the oldest waveform file is deleted when the
CF card is full. When all wave
form
files within a date folder have been deleted, the folder
name (date) is automatically updated.
(Example:) Before updating: 12-07-17
After updating: 12_07_17_120719_101113 (old
date_
new date _new day and time)
Hyphens (-) are changed to underbars (_) and the date when the folder name was last
changed is appended.
(The example shows a new date and time of July 19th 2012, 10:11:13.)
*3 The TXT file extension is applied except when
[Separator:Comma] is selected on the
[System] screen.
*4 Before loading data into a spreadsheet program such as Excel, note that the number of
rows that can be
loaded at one time is limited (to 60,000 rows in Excel 97 – 2003, and to
one million rows in Excel 2007).
Larger CSV files can be split by the following methods:
• Use a CSV file-splitting program (downloadable for free from Hioki's website).
• Before saving, select the [Split Save] saving method in the HiLogger.
Note: The number of rows recorded per minute with 10 ms recording interval is:
100 (data points per second) x 60 (seconds) = 6,000 rows
