When auto save is enabled before starting measurement, data can be automatically
saved to removable storage during or after measurement.
The following types of measurement data can be auto-saved.

Description
Waveform

Waveform
(realtime)
.MEM
During measurement, waveform data is saved in binary format.
Conversion to text (CSV) format can be done later, so we sug-
gest selecting Waveform(realtime) for typical operation.

.CSV3
During measurement, waveform data is saved in text format.
Saved data cannot be reloaded into the HiLogger or by the Log-
ger Utility. However, this format is ideal for loading into spread-
sheets like Excel.

.CSV3
Calculation results are saved after measurement.
When [Repeat]
recording is enabled (On), each measurement's
calculation results are appended to the file.
When [Split Calculation] is enabled (On), calculation results
are appended at each save interval.

Waveform data is saved in text format during measurement, and
calculation results are saved at the end of measurement.
Saved data cannot be reloaded into the HiLogger.
1. Calculation must be enabled before starting measurement (p. 143).
*2. The recording interval setting is limited for [C
SV(realtime)] and [CSV+Calc] according to the
number of channels used.
For up to 15 channels (using U1-1 to U1-15), the rec
ording interval must be longer than 50 ms
For up to 30 channels (using U2-1 to U2-15), the
recording interval must be longer than 100 ms
For up to 45 channels (using U3-1 to U3-15), the reco
rding interval must be longer than 200 ms.
For up to 60 channels (using U4-1 to U4-15), the reco
rding interval must be longer than 200 ms.
To perform waveform calculations, the recording interva
l must be longer than 500 ms.
(Pulse, logic, and alarm channels do not impose such
limits.) Also, when opening a CSV file
in a spreadsheet program, the number of rows that can be loaded is limited.
*3. The TXT file extension is app
lied except when [Separator:Comma] is selected on the [Sys-
tem] s
creen.
Select from the listed op-
tions.
