Distance Calibration Procedure
NOTE: Although the RoadLazer is calibrated prior to
shipping, the sensor will need to be recalibrated periodi-
cally due to wheel wear, and also whenever the gun-arm
wheel is replaced.
NOTE: Before recalibrating, ensure that the gun-arm
wheel is inflated to 40 psi. and verify the wheel is the
proper number of revolutions (see
Diagnostics , page
8).
1. Measure and tape off an exact distance up to 1000
ft. Suggested distance is 300 ft - 500 ft.
NOTE: Any error made in this measurement causes
inaccurate line lengths.
2. Access the Distance Calibration Menu.
3. Use adjacent arrows to enter the length of the mea-
sured course.
4. Drive the RoadLazer to the beginning of the mea-
sured course. Line up the gun arm wheel exactly on
the first mark.
5. Press button.
6. Driver the RoadLazer in a straight line to the mark at
the end of the measured course. Stop with the gun
arm wheel exactly on the second mark.
7. Press button.
8. The system is now calibrated.
System Delay Set-Up
The start and stop of the guns in either solid lines or
skiplines may be delayed by a specified distance. The
One Operator System Delay
™
is designed to make the
striping job a one person operation by eliminating the
need to look back at the guns to trigger them at the cor-
rect time. With the System Delay set, all gun activity is
controlled using the mechanical pointer reference point
on the road ahead of the vehicle.
1. Enable the system Delay Setup Menu.
2. Sight the mechanical pointer with start of paint stripe
(B).
3. Measure delay distance from start of paint stripe to
gun. Measure from (A) to (B).
4. Enter measured delay distance with adjacent
arrows.
When system delay is ON, all gun switches including
HOLD/RESET will be delayed by the distance set in sys-
tem delay.
