I’ve been messing around with open grade some. So far the survey line seems to have a resolution of .1 meters or about 4”. Is this correct? Is this adjustable? Does the laser button only give you a flat line? No grade?
You need to enable high accuracy mode on the receiver.
How do I do that on the F9p?
I guess it could be the difference between msm4 and msm7
View-configuration view-NMEA(NMEA Protocal) Then click High Precision Mode
Then click send
then go to CFG Select 0-4 and click send again
I can’t guarantee that is the issue, but I had to do that.
