I have a new InCommand/L2 Direct command in my sprayer and was trying some things out today, I haven't put water in the system yet as I don't have heated storage and am not convinced we're done with winter yet, although it sure seems like it.  Will it paint the map without have anything running through the flow meter?  I drove through the field and the booms valves appear to open when the master switch in on and I'm moving, but nothing paints behind the boom on the screen.  The booms sections go from red to gray when the master switch is on, but never to green.  I would think it would paint, just show a 0 rate on the coverage map.
