You can use a meter for the active sensor, an AMMETER. It is acurite enough to test the sensor and the tone ring, you just have to go very slow. HOWEVER, an osciliscope would but the best and most perfered method. But not everyone has one they can use and it is for more likely that you can get a meter. Besides, at the dealer and here in the classroom, we use the multimeter.
