NOTE:  Note the location of the Dataset® arms on the rim. The 
location for rim runout measurement is NOT the same as the 
location for inputting rim dimensions for weight location. 
When Dataset® arms are in place, press the outer arm button. The motor will slowly 
rotate the wheel to measure runout. While the wheel is in motion, gently apply 
upward and inward fingertip pressure on both Dataset® arms as shown below: 
 CAUTION:  Take care when placing hands to measure rim runout that no 
part of your hands or body interfere with parts in motion.
NOTE:  Do not grasp the Dataset® arms. Use fingertip pressure 
only.
