contiguration

BY USING THE 'TRIAL'' PROGRAM (CIDVE
SA:210). ALL QUESTIONS SHOULD BE
answered and then each diagnostic will "'OVERLAY'' these parameters which
are stored in the ''STATUS TABLE'' (see section 8.4a).
The alternative to
"“TRIAL'' program is '‘AUTO SIZING'' (see section 8.5).

CZOVD LIKE C2DVC ALLOWS THE MICRO PROCESSOR TO ''FREE RUN''. BECAUSE OF
the
Llength
of
the
''free

test;
this test is to catch the

OVERFLOW FROM C20VC.

Currently there are six off Line diagnostics
that are
to
be
run

to insure that if an error should occur it will be detected at

an ;trly stage and insuring that diagnosis of error will be immediate to
