Closed Loop Calibration

Figure 12: Window showing the two options under the Closed Loop Calibration.

Both the Profile Slope and Cross Slope calibrations should be performed on a uniform surface
(ideally on a slab or an asphalt section). Do not start calibration with the wheels over a crack or
change level from slab to slab during calibration. When calibrating a new device, the height and
distance calibrations must be performed prior to either closed loop calibration.

The distance of the track should be between 10 and 30 feet (3 and 9 meters). This manual uses a
25ft (7.67m) segment for illustration.

Note: Base length (length from back wheel to laser) must be entered before calibrations can be
performed. This value typically ranges between 17 to 18 inches.
