Combine The Error Types - Fluke Calibration 5730A Operator's Manual

Figure 4-9 illustrates linearity error with both offset and scale errors assumed to be zero.
The formula for linearity error yields:
Linearity Error=
Calibrator Setting
Linearity
Error =
+7 mV

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.
