To confirm that a fluorescent lamp is good, two tests are
required:
1. Cathode continuity, at the pins on both ends of the lamp
2. Gas fill
Test Cathode Continuit
Insert the pins of a fluorescent lamp into the two red
receptacles. Twist the lamp slightly to make contact with the
pins.
Both pins must touch the internal contacts at the same time.
A green light (A) and an audible tone designates that the
cathodes are intact.
