Voltage Detection with Probe
Do not touch the energized bare parts with the probe. Test on
energized insulated parts or insulated wires only.
To avoid electric shock, do not touch ANY part of antenna during lamp
or voltage tests. Touching antenna during these tests affects tester
sensitivity.
1. Turn the light fixture's power on.
2. Use the probe to detect the presence of ac voltage on the wires at
input of the ballast.
• If the tester's LED flashes red and beeps, there is ac voltage present.
3. Use the probe to detect the presence of ac voltage on the wires at
output of the ballast.
• If the tester's LED flashes red and beeps, there is ac voltage present.
The lamp may be faulty.
• If LED and beeper do not activate during voltage detection at the
ballast output wires, the ballast may be faulty.
