Quality Codes:

The following table gives the quality code which will be displayed with a point. If a point can have more then one quality code, the code nearest the top of the table will be the one displayed.

Description

Quality Code

Operator entered (Manual entry)

"M"

Point in test

"T"

Point offscan (no EU conversion being performed)

"S"

Exception (Scan, mathematical or validity)

"X"

"I"

Secondary quality is not zero

"?"

No abnormal quality

" " (Blank is displayed)

The secondary quality consists of the compositing of the primary quality and secondary quality of all other points used in the EU conversion of a point. The primary quality consists of four conditions: operator entered, point in test, point offscan, exception.
