Introduction to the MATH-PAK Option
2–3
When the MATH-PAK option is installed, the results information for each
inspection is also available for use in MATH-PAK formulas. You can define
formulas to combine or manipulate, in any number of ways, the inspection
data gained from one or more tools used in the inspection.
Figure 2.2 illustrates how the inspection results can be manipulated by
formulas with MATH-PAK installed.

1: Formula results can be
range-checked instead of, or
along with, tool results.

replace, or be provided along
with, tool results.
No
Range limits and output assignment: For each formula you define, as with
the inspection tools, you can set warning and fault range limits for the
results, and assign the range limits to discrete outputs (see Figure 2.2).
