[volt-nuts] 3458a RAM batteries - longer life if unit is continually powered?

[Dr. Frank]

Hi Poul-Henning,

you've misunderstood, what I've done..

I simply searched the text fragments directly in the binary file, with a 
HEX-editor.
I did no SW-reverse-engineering!

I just wanted to identify, which failure (text) messages come up, when 
either the config RAMs, or the cal RAM fail...

Nobody up to now reported the correct failure messages in case of 
failure of the 8kB CAL RAM.

But perhaps you can tell from your reverse enginieering, what the error 
message would be?

regards Frank
