The lot number is used to identify particular sets of data. The lot numbers are allocated successively
until 100, even if some lots were deleted. The total number of lots that can be saved is 100. If
some are deleted (for example 1‑50), fifty additional logs may be stored. These will be numbered
101‑150. The lots are allocated successively (provided available memory space) until 999 is reached.
After this, it is necessary to delete all the LOT logs to start over the numbering.
