the Current Value bar and dial screens.

Tolerance Description
Pass Above low warning and below high warning. Pass
values fall within the specified range of acceptable
values.
Warning Outside the range of pass values, but not at or
beyond the specified acceptable limits. Warnings
indicate the need to evaluate the process to prevent
the future generation of unacceptable, or failed
parts.
Fail Outside the specified range of acceptable limits
specified.
Max/Min Highest and lowest graph scale values. These
values determine the range of values plotted on the
graph. This range should be greater than the range
limits of acceptable limits.
The colors used to indicate pass, warning and fail can be
changed using the Display setup screen on page 123.
