What are the problems of one-point calibration?

Only ensures a single point is correct against the standard but cannot correct for incorrect linear gradients May result in inaccurate measurements at the extreme of the measurement system...

What are the problems of two-point calibration?

Useful for correction of linear systems correcting for both linear and gradient drift between calibrated points May result in inaccurate measurements when the system behaves in a non-linear manner (dashed line) or the measurement system changes behaviour outside the...

What is multi-point calibration?

The most accurate form of calibration Involves measuring multiple points against a standard and correcting for sensor offset against these points The correction can then be applied to all measurements using a line of best fit between the points Can be useful when a...
