Title: 2nd card/ch T2 trim not close
Post by: Peter on February 01, 2021, 12:16:00 PM

I connect my DMM as advised to calibrate card1, success. :-)


When I start with ch2/card2 I can't trim T2 to match off/on VAC. It differs at the best around 1 VAC

As is I connect DMM to the back on my lunch box. Else, which TP's on card2 is preferred?

On channel 2, the input signal just after unbalancing is on TP6
and the output signal just before re-balancing is on TP7.
You can see this clearly on the schematic.
