3.4 Rolling Compensation
NOTE: This procedure can be performed using the 3-point or 2-point
compensation method.
CAUTION: This procedure should be performed only on a pit-installed rack,
and should not be performed on a lift or above-ground rack. The
vehicle could roll off the lift/rack, causing severe personal injury
and damage to the vehicle, or rack.
From the “Control Compensation” popup screen, press “Use Rolling Compensation.” The
“Rolling Compensation” popup screen will appear.
3-Point Procedure
Position the vehicle so that it can be rolled forward, with the wheels able to rotate 240°.
Level and lock the sensors, then press “Ready.” When the sensors are stable, the
measurements will be saved.
NOTE: Beginning the rolling compensation procedure removes any old
compensation from the sensors.
The screen instructs you to roll the vehicle forward so the wheels rotate 120°. Vertical bar
graphs show when this is correct. Unlock the sensors and roll the vehicle forward until
the arrows are in the null position.
Level and lock the sensors. The green LED must be on at each sensor.
