I am doing a project of getting power reading from a meter into a pc via RF module. However I found that wireless transmission has its own power as well. So whenever I try to get my RF module near the meter, even without any load connected to the meter, there is also slight reading on the current and results in power. Can anyone suggest methods to overcome this or theory behind this? Thanks. :D

Hello,

I think your meter has troble with RFI (Radio Frequent Interference).
The meter is detecting the RF signal by itself.
Using shielded cables might help.(if possible).
