Now as everything is (hopefully) working fine you should gather some data. I'd recommend to use a fixed place for the field mill. Otherwise the data would be hard to compare. The local field parameters may vary a lot from place to place. I configured the mill that it took one measurement value every hour. I let the mill run for about 3 months.
