Checking for the Magnetic Field (NCV-1040)
The NCV-1040 can test for a magnetic field in
addition to AC voltage detection. A solid yellow
LED will illuminate when a magnetic field is
detected.
Note: If AC voltage and a magnetic field are
detected simultaneously, the Tester will flash both
red and yellow.
