Up to now only PID A is populated (exept D) after Hacking the logic at the S&H IC, it works as expected. after switching in hold mode, the current seems to be a bit lower than the initial setpoint. this might be caused by the big hold capacitor. Maybe after 0.5 sec. it is not entirely loaded. The hold time seems to be huge, after 30s there is almost no change visible, seems to be a fraction of a Millivolt. So it might be an option to change the Cap to a smaller one, leading to a smaller hold time, but a more precise hold value. | Up to now only PID A is populated (exept D) after Hacking the logic at the S&H IC, it works as expected. after switching in hold mode, the current seems to be a bit lower than the initial setpoint. this might be caused by the big hold capacitor.
