Monitor Performance shows the heading error and tracking error. It is designed to tune Advanced AutoTrac Settings.
Tracking error displays the machine off-track error or offset relative to the current track. Distance is shown visually with the path accuracy indicator and by the value in the middle of the indicator.
Heading error indicates the relationship of the machine direction relative to the current track. Heading error should be within +/- 1° on a straight track. Heading error may be larger while on a curve track. The arched bar graph value updates minimum and maximum heading error changes live during last 10 seconds.
