1. A method for displaying, on a balancer, an imbalance of a rotating body, comprising the steps of:
- establishing a static imbalance threshold associated with an acceptable static imbalance of the rotating body;
establishing a dynamic imbalance threshold associated with an acceptable dynamic imbalance of the rotating body;
calculating both a static imbalance and a dynamic imbalance of the rotating body having an unknown imbalance; and
providing a display of a relationship between said calculated static imbalance and said associated established static imbalance threshold to an operator together with a display of a relationship between said calculated dynamic imbalance and said associated established dynamic imbalance threshold to an operator.

Abstract
A method for determining weight display thresholds for static and dynamic imbalances and correction weights on a rotating body such as a vehicle wheel assembly, which vary with parameters of the rotating body, wheel and/or tire, and for displaying measured imbalances in relation to determined imbalance thresholds.

4. A method for displaying, on a balancer, an imbalance of a rotating body, comprising the steps of:
-
establishing a static imbalance threshold and a dynamic imbalance threshold; calculating a static imbalance and a dynamic imbalance of the rotating body; and providing a display of said calculated static imbalance in relation to said established static imbalance threshold to an operator, together with a display of said calculated dynamic imbalance in relation to said established dynamic imbalance threshold to an operator; and wherein the step of providing a display further includes generating a scaled representation of said calculated static imbalance and said established static imbalance threshold together with a scaled representation of said calculated dynamic imbalance and said established dynamic imbalance threshold, each of said displayed representations scaled to fit within a display region. - View Dependent Claims (7, 10, 11)

12. A vehicle wheel balancer system having a central processing unit operatively coupled to receive imbalance data from imbalance sensors, and a display controlled by the central processing unit, comprising:
-
a memory operatively coupled to the central processing unit, said memory storing a static imbalance threshold for a vehicle wheel having an unknown imbalance undergoing an imbalance measurement procedure and a dynamic imbalance threshold for said wheel; wherein the central processing unit is configured to calculate both a static imbalance and a dynamic imbalance of the vehicle wheel; and wherein the central processing unit is further configured to control the display to present a representation of a relationship between said calculated static imbalance and said stored static imbalance threshold together with a representation of a relationship between said calculated dynamic imbalance and said stored dynamic imbalance threshold. - View Dependent Claims (13, 14, 15, 16)
