Why is Calibration Important

The following figures depict how a properly performed calibration can improve product performance.

If a product were perfect from an accuracy standpoint, then the results for a series of tests would form for the curve in Figure 1 labeled “Ideal Results”.  But what if the test results form the curve labeled “Actual Results?  Although the curve has been greatly exaggerated for the purpose of this discussion, there is an error at any point within the operating range with respect to the Ideal Curve.  In addition, the error is not constant over the operating range.

Calibrating the product can improve this situation significantly.  In Figure 2, the product is “taught” using the known values of Calibrators 1 and 2 what result it should provide.  The process eliminates the errors at these two points, in effect moving the Actual Results curve closer to the Ideal Results curve.  The Error At Any Point has been reduced to zero at the calibration points, and the residual error at any other point within the operating range (exaggerated by the curve) is within the manufacturer’s published linearity or accuracy specification.
