Figure 4-9 illustrates linearity error with both offset and scale errors assumed to be zero.
The formula for linearity error yields:
Linearity Error=
(10.0 – 9.993)
= 0.000352 = +0.0352 %

Figure 4-9. Linearity Error
Combine the Error Types
The actual error of a meter is the combination of all three types of errors. The Calibrator
uses the Scale and Offset selections to separately show all three types of errors directly,
without any calculation.
