3. Compensating Sensors
3.1 General Compensation
The sensors must be compensated to eliminate errors in angle measurements caused by
runout of the wheel, wheel adaptor, and sensor shaft.
The sensors must be “ON” to compensate.
Do not disturb the sensor until the two outer LED’s respond.
Sensors may be compensated in any order; however, these precautions must be followed:
If a sensor is removed from a wheel, that sensor must be re-compensated when
reinstalled. The other sensors do not need re-compensation.
During two-point compensation and normal operation, be certain no obstructions are
blocking the infrared beams between the sensors. When compensating sensors that
are mounted to the vehicle drive wheels, place the transmission in NEUTRAL.
The lift/rack should be level and on the leveling legs, if so equipped.
3.2 Three-Point Compensation
All sensors need not be mounted before starting compensation.
Raise either the front or rear axles, or both, while remembering to use the safety on all jacks.
WARNING: If only one axle is to be raised, chock wheels on the axle
that is not being raised (before raising), to prevent the
vehicle from rolling.
Turn sensors on and select any one of the sensors for compensation. The starting position
of the wheel adaptor does not matter. The middle LED will be on.
Hand-tighten the sensor lock knob.
Rotate the wheel until the sensor is level (as indicated by the spirit level on top of the
sensor).
Press the compensate button. Do not disturb the sensor until the two outer LED’s begin
to blink and the middle LED turns off, indicating that the measurements have been
stored.
Loosen the sensor lock knob and rotate the wheel 120°, clockwise or counter clockwise,
until the middle LED turns on. Hand tighten the sensor lock knob and rotate the wheel to
level the sensor.
NOTE: It is recommended that the front wheels of front wheel drive
vehicles be rotated in the forward direction to reduce disturbing
the sensor on the opposite front wheel.
