Fabio, I uploaded the EPROM contents from my meter to Didier's site as well. The Floating board I have has 'AA' version firmware while yours is 'CA'. Mine uses TMS2516 chips that are 24 pin and I think yours are 2764 28 pin chips.
I'll investigate the statistics function after I make sure it is 'in range' as far as the calibration goes. I don't understand 'SP1 and SP2 on floating board are both open circuit'. To what does this refer? Thanks.

Another thing is that on mine SP1 and SP2 on floating board are both open circuit. Fabio. "J. L. Trantham" <[email protected]> ha scritto: > Fabio, > > Thanks for the link to the pictures.
