How can I determine the presence of live AC wires behind a wall with this stud sensor?
Holding it as instructed, slowly move the sensor across the wall while pressing and holding. If the AC LED illuminates, you are near 6-18" from active AC wire; AC LEDs along with center red LEDs indicate AC voltage at stud's center when detected (Pages 5-7).
