Hi,
I have not thoroughly analyzed the dump.
But, during the period when I was working on the A201 module, there was an attempt to replace part of the dump (modification) of the American version of SN (7-digits) with the European (8-digits), which did not lead to anything.
The Flash Tool did not accept the SN that I was trying to enter in the "Instrument: DM" field.
There should be a mechanism for calculating the checksum, but I do not know it.
In fact, you have everything to get started with this work.

Plus Fluke probably uses serial number ranges for the scopemeter's various models.
Good luck!
