DTM-1 has internal memory to save Production report without Pen-drive or Computer.

It can store up to 32000 Tests in its internal memory.

Saved data can transfer to pen-drive for backup.  Above page shows to transfer the ONBoard data (Internal Memory) to the pen-drive.

There are Three options as the user can save last un-backup test or previous 1000 Tests or previous 32000 Tests from the ONBoard internal memory to Pen-drive.
