Armature Bar-to-bar Test Fixture
For armature bar-to-bar testing, the ATF-5000 test
fixture is required. Refer to the instructions
provided with the fixture for details on using and
maintaining the fixture. The fixture’s connectors
attach to source and sense connectors of the
Baker ZTX, Baker PP85, or Baker DX15A.
During bar-to-bar testing, adjacent bars on the
commutator are tested. In turn, all adjacent bars
around the circumference of the commutator are
tested. For example, bars 1 and 2 are tested, then
bars 2 and 3 are tested, then bars 3 and 4 are
tested. The pattern continues until all
commutator bars are tested.

Armature Span Test Fixture
For armature span testing, the ATF-4000 test fixture is required.
Refer to the instructions provided with the fixture for details on
using and maintaining the fixture.
During span testing, a group or span of bars is tested. For
example, one contact is placed on bar 1 while the other is placed
on bar 5, creating a span of 5 bars. Bar 1 and 5 are contacted
first, followed by bars 2 and 6, and so on until all bar spans are
tested.
