Metrohm 9A
Does anyone have circuits for these please?
I have several in various states of disrepair, bought as a job lot, and it would be nice to make at least one working meter from them! |

Re: Metrohm 9A
Attached circuit and other info from the manual for Metrohm9A. All rather small, so I hope you can read enough from it. The snag is the main part of the machine is the Hybrid, on which I have no information. If that is gone, then the small print of the rest of the circuit is of little concern. Bill m0wpn
