For the setting procedure, see section 1.12, “Setting Recording Conditions (Recording
mode, recording interval, saving interval)” and 1.11, “Setting Measurement Conditions (Scan
interval, A/D integrate, etc.)” in the User’s Manual.
For operating instructions, see section 2.1, “Starting and Stopping Recording and
Computation” in the User’s Manual.
Type of Data to Record
You can choose to record display or event data.
• ChoosingWhatTypeofDatatoRecord
Record the type of data that meets your needs. Use the following examples for reference.
Example 1: Record continuous waveform data only, just like conventional chart sheet
recording instruments.
Record the display data.
Example 2: Continuously record data that is as detailed as possible.
Record event data by specifying the recording interval.
Internal Memory
The measured data is partitioned and saved to files at set intervals. If the internal memory
is full or if the number of display data files and event data files exceeds 500 for GX10/GP10
and GX20-1/GP20-1 or 1000 for GX20-2/GP20-2, files are overwritten from the oldest file.
Recording Conditions of Display Data

Auto Save
The following type of files are automatically saved: display data, event data, manual
sampled data, and report data (/MT option).
Keep the SD memory card inserted in the drive at all times. The data in the internal memory
is automatically saved to the SD memory card.
For the setting procedure, see section 1.14, “Setting the Conditions for Saving Data Files”
in the User’s Manual.

sampled data
The first time manual sample is executed, a manual sampled data file is
created on the SD memory card. Data is appended to this file at every
subsequent manual sample operation. A new file is created after manual
sampled data is stored 100 times.
For operating instructions, see section 2.5.3, “Manually Saving
Instantaneous Values of Measured Data (Manual sample)” in the User’s
Manual.
Report data The first time report data is generated, a report data file is created on the
SD memory card, and report data is stored. Report data is appended to this
file at every report interval.
Dividing of the report files
The appending of the report data to the file is stopped at a specified time,
and subsequent reports are saved to a new file. The file is divided in the unit
shown in the table below. Also, when recording is stopped, all report files
are divided.
Report template function
Every time a report file is divided, a report file is created according to the
specified template format such as an Excel format or PDF format. The
report file can also be printed.
For the setting procedure, see section 1.16, “Setting the Report Function
(/MT option)” in the User’s Manual.

Save Destination
Files are saved to an SD memory card.
Data Save Destination Directory
You can specify the name of the directory that data will be saved to (the default directory is
“DATA0”). The GX/GP will create the directory on the SD memory card and save data to it.
For the setting procedure, see section 1.14, “Setting the Conditions for Saving Data Files”
in the User’s Manual.
Note
Do not place a file with the same name as the directory name (“DATA0” by default) in the SD card.
Save Operation (When not using media FIFO)
If there is not enough free space on the SD memory card, the GX/GP cannot save the data
in the internal memory to the SD memory card. Replace the SD memory card before the
data in the internal memory is overwritten.

SaveOperation(Alwaysretainmostrecentdatafile/mediaFIFO)
When saving the data files automatically, you can save the data so that the most recent data
files are constantly retained in the SD memory card. This method allows you to use the GX/
GP continuously without having to replace the SD memory card.
For the setting procedure, see section 1.14, “Setting the Conditions for Saving Data Files”
in the User’s Manual.

If not enough free space is available when saving a new data file to the SD memory card,
files are deleted in order from the oldest data update date/time to save the new file. This
operation is referred to as FIFO (first in first out).
• FIFOisusedonlywhenthefollowingfilesaresavedautomatically.Whenfilesaresaved
using other methods, FIFO is not used.
Display data files, event data files, report data files (/MT option), manual-sampled-data
files, and snapshot data files.
• Filessubjecttodeletion
All files in the destination directory, except for the ones listed below, are subject to
deletion. Files not subject to deletion:
Hidden files, read-only files, files in the subdirectory within the save destination directory
• IfthefreespaceontheSDmemorycardwouldfalltolessthan1MBafterthefileis
saved, the oldest files are deleted in order from the save destination directory before the
file is saved. The GX/GP ensures that at least 1 MB of free space is available after a file
is saved.
• Uptothemostrecent1000filesareretained.Ifthenumberoffilesinthesavedestination
directory exceeds 1000, the number of files is held at 1000 by deleting old files even if
there is enough free space.
• Iftherearemorethan1000filesalreadyinthesavedestinationdirectory,atleastonefile
is always deleted before saving the new file. The number of files is not kept within 1000 in
this case.
