giuliomoro So when we say "calibrate" do we mean swap resistors/pots in and out such that we get 4.096V from 10V on each channel?
Should I try to measure the resistance across both of them whilst they're still on the board using a multimeter first?
The resistors on the schematic give 4V in an ideal world, don't they? So I'm looking for pots and resistors with slightly more or less resistance to substitute?
eg. when the value of the pot is accurate at 100k I need to find a resistor at 144.141k?
or when the resistor value is accurately 150k I need a pot that goes between 0 and 104.065k?
Is trial and error the only way to resolve this?
I'll confirm that the ratio is correct/different to the others for the first channel which gives the full range of values before desoldering anything
I've also noticed another issue! My analog outputs all clip at approximately 0.94V!
