This uses analogue input A7 and a 100k - 4.7k divider, same as the Vcap input divider R23 and R25 on the Controller board. It actually works out very neat as it utilizes spare pin 6 on J5-J6 and the same calibration as the existing VCap ADC. The results are perfect, there is absolutely no ADC cross channel coupling with AC current input A6 or other ADC channel.   It's completely automatic, if a voltage > 10v is on ADC 7 then the LCD displays it instead of the Code Version number: LCD displays "Ca2 53.2v", once A7 is below 10v, the LCD reverts to "Ver 7.5ks"   If I find I don't need a Ca2 display (monitor the second cap bank) then it can be used for any other purpose required. _ Edited 2024-07-31 13:56 by KeepIS
