Inspector 4000 Analysis Parameters

Reference Decode

This parameter grade can be “A” or “F.”

If the Reference Decode parameter is “F,” then the overall symbol grade is also “F”

(regardless of the grade of any other parameter).

If the Reference Decode parameter is “A,” then the overall symbol grade is determined by the

lowest of the other parameter grades.

When a symbol contains a global threshold failure (an element does not cross the global

threshold), other parameters cannot be analyzed.

 In the case of a global threshold failure symbol contrast calculations are valid, however.

 In the case of a global threshold failure, the Inspector 4000 will force the decodability

grade to 00% (an “F” grade).

 Other affected grades will be calculated only for that portion of the symbol which was

scanned up to the point of the global threshold failure.

The Inspector 4000 also decodes each symbology with a more aggressive algorithm. This

enables many symbols to be scanned and decoded even though the reference decode grade is

an “F.”
