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.

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.

During measurement, waveform data is saved in text format.
Saved data cannot be reloaded into the instrument or by the
Logger Utility. However, this format is ideal for loading into
spreadsheets like Excel.

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.

1. Calculation must be enabled before starting measurement (p. 183).

2. When using the [CSV (realtime)] and [CSV+Calc] settings, the available recording interval
settings are subject to limitations based on the total number of analog, alarm, and wave-
form calculation channels (when alarms are on, fixed at four channels).

Up to 35 channels: No limitations

From 36 to 75 channels: The 100 ms setting is not available.

76 or more channels: The 100 ms and 200 ms settings are not available.Also, when open-
ing a CSV file in a spreadsheet program, the number of rows that can be loaded is limited.

3. The TXT file extension is applied except when [Separator:Comma] is selected on the [Sys-
tem] screen.
When communications with a measurement unit and/or a wireless logger
are reestablished after a temporary interruption while automatically saving
waveform (binary) data, data being saved is also restored when missing
data is restored. However, when using the split save setting, data in files
that have already been split and saved will not be restored. Only data
associated with files that are currently being saved (i.e., that have not yet
been split) can be restored. When automatically saving data in the CSV
(text) format, saved data is not restored. Additionally, data cannot be
restored if the data in question cannot be found on the media, for example
if the media has been changed.(p. A33)
