Calibration and
Diagnostics
This balancer is a precision measuring instrument.
As such, it will require periodic calibration. The need
for calibration is generally identified when the bal-
ancer begins to "chase" weights - multiple spins and
multiple weights are required to achieve a "zero" bal-
ance. It is important to note, however, that even
though multiple spins and several weights may be
required, the wheel is properly balanced when the bal-
ancer indicates as such.
Before performing the calibration procedure, clean
and check the shaft, faceplate, and balancing cones
for damage. Even the slightest amount of dirt or dam-
age can cause inaccurate calibration and balancing.
Balancer Calibration
Balancer calibration is a quick, simple process that
the operator can perform. A 4-ounce calibration
weight and an automotive steel wheel are all that are
required.
1. Select CALIBRATE from the menu, then select
CALIBRATE BALANCER.
2. Mount a 185 x 14 or 195 x 14 wheel, and enter
the standard A, W, and D measurements.
3. Lower the hood to spin the wheel (or press
START if HOOD START is turned off).
4. After the spin, attach a 4-ounce weight to the
wheel at the position indicated by the flashing weight
positioning LEDs.
If the weight cannot be placed in this location
(weights already on the wheel, etc.), place the weight
anywhere on the rim flange, rotate the wheel until the
weight is at top-dead-center, and press * on the key-
pad.
5. Lower the hood and spin the wheel again.
The display will show CALIBRATION COMPLETE.
