Hej til alle jer kyndige DIY..
Mon der bor en i Horsens området som kan hjælpe mig med en justering.
Jeg kom i vanvare til at justere på en forkert pot, og nu skal jeg bruge både det ene og andet til justering..
Er der en venlig sjæl som vil hjælpe mig i min nød - og ingen sliber jo uden vand - så det finder vi ud af :)... Det er
bare træls det her.. :(

Her er hvad Anthony skriver:

The procedure for adjusting the other white pot is as follows.
To readjust the CMMR you are going to need a good quality Multimeter or AC millivolt meter and a means to inject
a 500 Hz Sine wave signal at 500mv
into Non-inverting and Inverting inputs at the same time.
To do this you need to connect or short both inputs together and connect your signal source to both +- inputs
and connect
the signal GND from your source to signal GND of the Amplifier module.
Then connect your AC millivolt meter to the output of the amplifier module.
Then power the module up and adjust VR anticlockwise for as low as setting as possible.
This would be typically lower than 10mv AC and you may be able to adjust as low as 4mv, as you trim to the
lower setting you will find the adjustment
a bit harder to trim and may find the reading may go back up. This just means you have over adjusted it and
you need to adjust in the opposite direction.
