COATS 950 Pro Racer Wheel Balancer - Manual (Page 13)

Wheel Data Entry
Before a wheel can be balanced, the size of the wheel must be
entered into the computer. The user enters the data manually.
Wheel Offset — A
This is the distance between the edge of the balancer and the
inner edge of the wheel.
Manual Entry - Press the wheel offset key. Pull the distance
gauge out in the same manner as outlined for automatic entry.
Hold the gauge against the wheel flange and read the measure-
ment on the gauge. Use the keypad to enter the measurement.
For example, if the last large number (inch indicator) visible is 6,
and the last small number (fraction of an inch) visible is 4, press
6 then 4 on the keypad to enter 6.4 inches.
Wheel Width - W
This is the width of the wheel measured with the calipers at
the rim flanges.
1. Press the wheel width key.
2. Open the calipers wide enough to reach around the tire.
Close the calipers so both tips contact the rim flanges. Read the
rim width on the calipers.
3. Enter the measurement using the keypad. It is now shown
in the display above the wheel width key.
Wheel Diameter - D
This is the diameter of the wheel at the weight location.
Manual Entry - Press the wheel diameter key. Locate the tire
size on the tire sidewall and determine the wheel diameter. Use
the keypad to enter the measurement. It is now displayed above
the wheel diameter key. The computer calculates the actual
weight placement diameter.
