Is the bin bin loader auger on your R62 tapered on the outlet endIJ I only used mine on wheat and when I would get into an area of weeds or wetter wheat it would build up on the sensor until the load was above the auger. Moisture would be accurate until then but would register 40 - 50% until the sensor was cleaner off. I haven't used it yet in corn or millets to see if it is an isolated problem. The taper in the auger flighting starts just where the sensor starts to pick up the grain. I feel this prevents the grain from being pushed through the sensor.
