Choosing Test Conditions
The source and load resistors and the fixture transformer for the IEEE and
FCC methods are assumed to be on the fixture, but are not shown on the
Editor schematic. They are switched in circuit using an OUT test that must be
inserted in the program before the GBAL test. (The relay patterns associated
with inserting and removing fixture resistors have deliberately not been
included in the GBAL test dialogue for two reasons: a) it would make the
dialogue too complicated, and b) it is not always necessary, e.g. in the case of
a fixture where the resistors are permanently fitted in circuit).
