FYI Agratronix BHT-2

Most of you probably already are aware of this,but I certainly wasn't. When I turned monitor on and pushed cal. button I got "err" message and 14 -16% reading with no hay in baler. Finally remembered, last job I did was 15 miles from home,so I left baler in field. Got 1/2 inch of rain. Long story short. There was a little dirt,dust and water behind sensor pad giving false reading. Cleaned pad and side of bale chamber,problem solved. BTW round baler,guess it could happen on square also.
