Amprobe LT-10 User Manual page 14

• Do not use if the instrument appears damaged or if it doesn't operate
properly. Closely examine the tip of the probe for cracks or breakage
before use. If in doubt, have the instrument serviced.
• Do not use the instrument to test voltage higher than the rated voltage
as marked on the instrument.
• Use caution with voltages above 30 V ac as a shock hazard may exist.
• Comply with local and national safety requirements.
• Use proper protective equipment as required by local or national
authorities.
The non-contact voltage (NCV) test can be used to check whether the
ballast is functional by verifying the presence of ac voltages at the input
and output of the ballast, or the energized parts of the light fixture. The
light fixture must be turned on before verifying the presence of ac voltage
with the instrument.
Voltage Detection with Antenna

Do not touch the energized parts with the antenna.
1. Turn the light fixture's power on.
2. Use the antenna to quickly check the presence of ac voltage to the light
fixture.
• If the LED flashes red and beeps (modulated), there is ac voltage
present.
