Storage
Measurement data saved in the internal memory can be saved in an external storage medium
(SD card) automatically or manually.
Auto Save
Measurement data in the internal memory is saved automatically to an external storage medium
(SD card).
Keep the SD card inserted in the drive at all times.

Media FIFO Function
If not enough free space is available when saving a new data file to the SD 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).
When saving the data files automatically, you can save the data so that the most recent data
files are constantly retained in the SD card. This method allows you to use the GM continuously
without having to replace the SD card.

Media FIFO Save Operation
• 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.
• FIFO is used only when the following files are saved automatically. When files are saved
using other methods, FIFO is not used.

Manual Save (Collectively Storing Unsaved Data)
If you do not use the auto save function, save measurement data manually.
Unsaved data in the internal memory is stored in files to the external storage medium (SD card)
when an external storage medium is inserted.
When using manual save, you must be careful to save the data in the internal memory to the
external storage medium before the data is overwritten.
