## Description of Column Names

ID

The X-Axis values on the measurement deviation chart.

Variable Name

The name of the feature variables.

Actual

Measured value.

Nominal

Target value.

LowerTol

The lowest amount of acceptable deviation from the nominal. The lower tolerance should always be less than the upper tolerance. DataPage+ calculates specification limits by using the following equations:

The lower tolerance should be negative so that its value is less than the nominal.

UpperTol

The highest amount of acceptable deviation from the nominal.

Deviation

The deviation is how much the measured value deviates from the target value.

Deviation = Actual - Nominal

DeviationEx

This value is usually the same as the Deviation.

But, if UpperTol and LowerTol are on one side of the Nominal then it follows the distance between the measured value and centre of the tolerance zone.

OutOfTol

This value is 0 if the measured value is not out-of-tolerance. If the measured value is out-of-tolerance, then

OutOfTol = Measured Value - USL/LSL

Status

This shows the result of the of the transaction for all feature variables.

FAILED: This word appears if the measured value is above the 100% of the tolerance zone.

CAUTION: This word appears if the measured value is in between 75% to 100% of the tolerance zone.

PASSED: This word appears if the measured value is within the 75% of the tolerance zone.
