Hi every One!
I have a problem measuring a voltage signal from another device. The voltage seems to oscillate with about 2Hz… It seems that the source is galvanic separated, and needs to be, so how can I measure this voltage when I cannot connect “ground” ??
Hope this makes sense :)

Hi Martin
In a similar case I have used an isolation amplifier from PR-electronics, it worked without a problem.
here is a link:

I hope it helps

Hi Jacob
That was what i feared… I hoped it war passible to do this without any ”external” component. Today there is a PWM driver n the machine, and it is able to handle the galvanic separation, so having to add the PR module does not make it more simple ?
