I only built the first version without a meter and just have some crock clips I connect to a multimeter. I did intend to find milliameter, but so far havent bothered
. It works great though, sometimes I leave it on overnight if the leakage is still gradually coming down. Its quite satisfying to potter about and come back to it and check it
I dont think those readings are enough to worry about. As I learned recently, the resistance of your skin can provide 10M + resistance between 2 points on digital multimeter. Perhaps its coming from the cap where the tags are mounted?
