Linearity is the degree of conformity when the theoretical function (ideal output curve) is a straight line. It is a specific form of conformity, and its mathematical expression is summarized as: absolute linearity. Absolute linearity is the maximum allowable error of the actual output curve with respect to a fully defined reference line. It is expressed as a percentage of the total voltage and measured along the theoretical electrical stroke. Require a tuning point to be given on the actual output curve.
