Wheel Clamps 
X-631/X-631+ has 4 wheel clamps (see Fig.2.15).   
Turn the adjusting knob to adjust the span between 
wheel claws, and then attach the clamp to the wheel 
rim. Adjust the knob to make the wheel clamp fixed 
on wheel rim tightly. Use the wheel clamp tie to bind 
the wheel clamp and the wheel rim together.   
 
The installation of wheel clamp is crucial to the test 
result. The claws should be in even contact with the 
wheel rim without touching the lead weight.   
 
Avoid hitting during operation. Otherwise, distortion 
may be caused and the test result may be influenced.
