(15) Defragment storaged data (dFLG) panel
Up to 300 data can be stored. Unnecessary data can be individually deleted as in (1)
Stored measurement data panel (dAt). At the same time, individual deletion does not free
up memory occupied by deleted data, so may be displayed even though less
than 300 data are stored. In such a case, use defrag functions to compact storage and free
up the space occupied by deleted data, thereby allowing up to 300 data to be stored.
While data defrag is in progress, do NOT turn off the power. In addition, before starting
data defrag, check that the battery power is normal to avoid battery voltage dropout
during defrag.
