The example in Figure 4-8 assumes no offset error. The formula for scale error yields:  

Scale Error=

Figure 4-8. Scale Error 

Linearity Error 

Linearity error occurs when the response curve of a meter deviates from a straight line. 
This type of error is measured by fixing zero and near-full-scale endpoints on the 
response curve, drawing a line through the points, then measuring how far the meter 
response deviates from the straight line at various points. The error value is computed 
relative to the selected full-scale point. The formula for linearity error is:  

Linearity Error= 

(Nominal setting) – (Adjusted 5730A Setting) 

 

(Nominal Full Scale)

Where the “nominal setting” is calculated by subtracting the offset error and a 
proportional part of the scale error.
