With the current detector, the technician can pinpoint a specific conductor in a group that carries current. The technician pinpoints a specific conductor by reducing the sensitivity of the current detector. The technician moves the current detector near the current carrying conductor. When the current detector beeps and flashes, the technician repeats this process.
