How can I process acquired
data later with a spreadsheet
program? Auto-saved files recorded in [Wave-
form(realtime)] mode to removable
storage can be quickly and conve-
niently converted to a text (CSV) file
with the Utility Logger rogram, which
can then be loaded into a spread-
sheet program.
Auto-saved files recorded in
[CSV(realtime)] mode can be direct-
ly loaded into a spreadsheet pro-
gram, but note that the data cannot
be reloaded into the HiLogger. "Automatic Saving"
(p.97)
How can I load data from a CF
card onto the PC when it has
no CF card slot? Data can be transferred to a PC us-
ing the supplied USB cable and the
USB Drive mode. 6.6, "Transferring
Data to a Computer
(USB Drive Mode)"
(p.110)
How can I create files every
hour, from 0:00 (ideal split
time)? Set auto-saving
[Split Save]
to Peri-
odic (
[Ref Time]
).
”Automatic
Save”(p.47)
What is the file limit when auto
saving to removable storage? Depending on file size and CF card
capacity, more than 1,000 files can
be saved in one folder, although only
1,000 can be displayed on the file
screen.
As the number of files increases, the
time required to start and stop mea-
surement also increases, so we rec-
ommend storing no more than 1,000
files, if possible.
(When saving, a folder named
"HIOKI_LR8431" is created, and
files with different data types are
saved in subfolders within it.) 6.1, "About Saving
and Loading Data"
(p.91)
Is data retained in internal
memory when I turn the power
off after measuring?
I did not use auto saving to re-
movable storage. If the instrument is turned off with a
9780 Battery Pack with remaining
power connected or the Z1005 AC
Adapter connected, waveform data
will be backed up to the instrument's
internal memory. For the LR8431-20
with a fully charged 9780 Battery
Pack, the waveform backup time is
100 hours. "Waveform backup
time function" (p.145)
