50 Hz interference

Good morning,

I have to measure currents of uA, but I see an interference of 50 Hz, I have braided the wires, I am also using a grounded PC. I do not have access to a ESD mat, is there any more solution to mitigate this problem?

Thank you.


Actually, the ESD mat is not a solution, it can actually worsen the issue.
You should have short twisted cables, but it sounds like you have this.
Our experience is that electrically adjustable tables are a big 50 Hz noise source. Keep away from the control board and the cables to the up/down button. If you have your device close to this then you will have disturbance.

Best regards,
