Memory block
The internal memory is divided into several memory blocks.
Switching the storage area from one block to another is called “internal memory transition”.
A data file in a currently running block is saved before the data logging starts in a new block.
When the last memory block is used up, the DL30-G goes back to the first block and overwrite it.
One file per block is downloadable.
