Title: ProTack I 20, shows resistance
Post by: Al1234 on October 31, 2023, 11:57:26 AM
Hi everyone, I was wondering if I can get some guidance with this. Please.
The protrack shows a little bit of resistance on capacitor measurement. It does this with even brand new caps.
It passed the loop Calc the first time and a few more times.
I have done all the other check individually, as well and passed them.
All tests were performed without any leads connected.
Is this normal?

Hi
That looks fairly normal to me.
But I do think you could make some adjustments on the HV circuit board to sharpen up the trace.
See my photos of a ProTrack capacitance  trace under current hardware surface mount capacitors on this Forum.

Thank you jvthorsley, I will make the adjustments. Adjustments are those 3 potentiometer on top left?
But the signitures show a bit of leakage no?
I had to take the frequency all the way down to 30 to get this.
Ohm 20. V does not matter on cap measurements but it was on 4.

Really big caps always so a little bit of angle.
