> Example

You have set the Standard for a test point to 100, the Tolerance from 10% to 20%, and the Service % to 75%. The test point fails with a reading below 90 or above 120. The test point requires recalibration for readings in the ranges of 90 – 92.4 and 116 – 120. The test point passes with a reading that falls in the range of 92.5 – 115.
