Hey JP,

For step 6 :
• TP1=1.5VAC / 1.49
• TP2=1.5VAC / 1.71
• TP3=1.5VAC / 1.49
• TP4=0.06VAC / 0.05
• U6 pin1 = 0vdc / 0



Thank you !

So the problem I have is that I cannot reach the targeted 2vac while switching on/off the module.
Out+ (while off) = 2vac
Out+ (while on) = From 0.93vac to 1.15vac using the trimmer t1.

Thanks for your help !

Hello JP,

Jumping on this thread since I have exactly the same issue. 
Voltage checks are OK, however, I noticed TP2 depends on T1 position, so step6, TP2 is not always 1.5 AC. Right?

I will try the bath this week, in the meantime do you have any suggestions to help me?

Thanks for your help!
