Hi everyone, I have recently built a Faraday Cage. However it seems to be working in reverse and amplifying the noise!
My test setup:
I place a 3.3 Mohm Bulk metal precision resistor across the terminals of the meter and measure the pk-to-pk noise using the meter.
I now place the meter inside of the cage (the cage is floating) but now the noise increases!
I now ground the cage and repeat the measurement and it makes no difference.
N.B The noise that I am seeing is 50Hz mains pick up. I have sealed the door of the faraday cage with copper tape and I am quite confident that the sealing is effecting.
Does anyone have any ideas?
I thank you all in advance
