The wheel field balancing equipment Verification regulation of the wheel field balancing equipment 1 Scope This regulation is applicable to the initial verification, subsequent verification and in-service inspection of the wheel field balancing equipment (hereinafter referred to as the balancing equipment). 2 General The balancing equipment is a testing equipment used to measure the unbalance value, and the phase of the dynamic unbalance point, for a wheel installed on an automobile. An electromechanical switching system shall be used to convert the dynamic unbalance value into a measurable electrical signal, and output its value after measurement and data processing. Observe the white mark applied on the wheel in advance with strobe light to determine the phase of unbalance. 3 Metrological performance requirements 3.1 In calculation of the relative minimum residual unbalance e, G40 shall be taken as the balance quality grade. 3.2 When the indication value Ai of each balance point meets the requirements for the indication error in 8.8A0
