Appendix C - System Test Sequence Listings
This appendix contains listings of the four System (built-in) Test Sequences. These are
included as example source files with the Test Sequence Compiler software. You may
find it useful to use one of these Test Sequences as a starting point in developing your
own User Test Sequences.
Sequence 01: Global Test
This Sequence allows Consumer or Professional Channel Status, and is quite tolerant
of all parameters:
