6. Operation
The AC/DC Voltage Detector is an ideal tool
for checking hot and neutral conductors,
detecting the presence of AC voltage at wall
outlets, fuses switches...etc.
It's also for checking the presence of DC
voltage of the automobile battery (system).
●Check the unit by pressing the self-test
button before making tests.
When press the self-test button, you can
hear an audible tone and can see a visible
red LED. This means the detector can work
normally.
● AC voltage detection:
Hold the holding portion of the AC/DC
voltage detector, and make the contact
testing tip contact or touch the object we
want to test (see Fig 1, Fig 2). If there is AC
voltage presence, you can hear an audible
tone and can see a visible red LED.
