7.11.3 Unbalance Calibration
The third section of program settings is unbalance calibration. It is used to initialize
the new machine and remove the old equipments’ measurement errors caused by
total loss from use , parts ageing and replacing, or strong impact.
Choose a wheel with small unbalanced value and install it on the balancer. Input the
wheel parameters then calibrate it as shown in figure 46.
Rotate the wheel to calibrate for the first time
without placing standard counterweight.
Rotate the wheel to calibrate for the second
time by placing a counterweight of 100g on the
outside of rim.
