COATS 950 Pro Racer Wheel Balancer - Manual (Page 10)

Balancer Operation
Overview
This machine is a two-plane, microprocessor-based computer
balancer. Any imbalance in a wheel, either static or dynamic, is
resolved into two correction planes (usually the inner and outer
flanges of the wheel) where corrective weights can be applied.
Pressing MODE and selecting the DYNAMIC, ALLOY, STATIC, or
RV mode can change the location of these planes.
Determining the Planes
On the 950 Pro Racer the operator must enter the measure-
ments. Detailed instructions begin on page 8.
When the wheel width is entered into the computer, it is auto-
matically added to the offset measurement to determine the
outer plane of the wheel. The wheel width is entered manually
by the operator as the “W” measurement.
Balancing a Wheel
When a wheel is spun, the balancer detects any imbalance
present. The computer calculates the weight needed to correct
the imbalance and the location for weight application. The
weight required to correct the imbalance is displayed on the con-
trol panel, and the weight positioning lights assist the operator
in positioning the weight application location at top-dead-center.
Weight displays and positioning lights are provided for both inner
and outer planes of the wheel.
The stop-on-top feature of the 950 Pro Racer is designed to
stop the spinning wheel with the outer weight application loca-
tion near top-dead-center. If no imbalance is detected
