Background

This test set is for relays.  It mainly tests the coil of the relay and so might also be useful for testing other electromagnetic coils.

Description

The test set requires an external battery which is connected by means of a three conductor cable terminated with a 1/4" stereo phone plug that mates with the "BG" soclet in the lower left of the front panel.
