Testing 6 - 7
Testing Off
Line
The following tests involve use of the test load and a Battery
Plant Simulator Test Set. Refer to the paragraphs above headed
“Battery Plant Simulator Test Set,” “Test Load Connection,”
and “Preparation for Testing Off Line” for the procedure to
connect a test load and for a Battery Plant Simulator Test Set.
Startup
1. Turn On the ac supply to the rectifier. The PWR lamp on
the test set should light brightly. If it does not light
properly, check the connection of the two small red and
black clip leads. They may be reversed or otherwise
incorrectly connected. These leads provide the operating
voltages in the test set, and the red lead should be
approxi27 volts dc with respect to the black lead.
2. The PWR lamp should remain lit during the remaining
tests as long as the ac supply is turned On.
