The Main Unit can compare test results with AutoTest rules based on industry standards, or up to four
user-defined rules. To pass, all parts of the chosen rule must be met. For a complete list of AutoTest
rules refer to Section 7.

NOTE:
Some predefined standards require that the number of connections (mated connector pairs)
