NOTES:
10. Absolute linearity is used to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
11. Relative linearity is used to determine actual change in voltage between two successive tap positions when used as a
potentiometer. It is a measure of the error in step size.
