"DTSX3000 Communications Guide (IM39J06B40-02EN)".
B8.3. Measurement Data Output
The DTSX3000 converts measurement data into converted data files and archives the
files into its internal non-volatile memory. The DTSX3000 converts measurement data
first into LAS format files and archives the files into its internal non-volatile memory. Files
are archived continuously in its memory area according to limits on minimum free space
and maximum number of files. When the memory area limit is exceeded, the oldest file
is deleted and the most recent file is archived. Thus, the memory area of the DTSX3000
always contains the most recent files.
TIP
You can select whether to have the DTSX3000 compress converted files before archival. For more
details, see Subsection B6.5.4, "Data Conversion Related Settings."
The DTSX3000 assigns a user-specified string and an automatically generated control
number as part of the name of each measurement data archive file. This control number
is related to the archive directory name.
This section describes the specifications of the memory area for archiving measurement
data, as well as the structure of an archive file name and its relationship to the archive
directory name.
