    • A method of calibrating a parameter entry device for a vehicle wheel balancer utilizes a parameter entry device having an elongated rod slideably and rotatably mounted to the balancer in parallel with the rotatable wheel-mounting shaft. A transverse arm having a known length and a wheel contacting tip is connected to the rod. A rotary encoder is coupled to the rod so that when the tip is positioned for measuring wheel components the encoder measures angular displacement. Angular measurements of two known radial positions are used for determining the relative angles between each angle and the rest position of the arm to establish a reference. Using the established reference, measurements for determining radius and diameter of various wheel components can be made.
    • 校准车轮平衡器的参数输入装置的方法利用具有可滑动地并可旋转地安装到平衡器上的细长杆的参数输入装置,其与可旋转的轮安装轴平行。 具有已知长度和轮接触尖端的横臂连接到杆上。 旋转编码器联接到杆,使得当尖端被定位用于测量轮部件时,编码器测量角位移。 使用两个已知径向位置的角度测量来确定臂的每个角度和静止位置之间的相对角度以建立参考。 使用既定的参考,可以进行用于确定各种车轮部件的半径和直径的测量。
