ATF-11 - Armature Test Fixture

The ATF-11 is a DC bar-to-bar accessory to the ALL-TEST PRO 31 and ALL TEST IV PRO 2000. It connects ALL-TEST leads to any commutator, so one hand is still free to operate the ALL-TEST. The span is easily adjustable by a simple CCW twist of the handle. The brass contact of the ATF-11 insure a positive connection with the commutator bars, and the ATF-11 may be used on armatures of any style or design. The adjustable span can be shortened to contact two adjacent bars, or expanded to test 10 to 20 bars. With this positive connection to the armature, the ALL-TEST can then be used to test the windings for internal shorts, reversed connections, or partial grounds.

Note: A wider span results in a more consistent comparison.
