Measures the electrical noise (also known as dirty electricity, line noise, or power line EMI) present on building wiring. Simple to operate! Just plug the meter into an electrical outlet to obtain readings. Measures a wide range of dirty electricity frequencies (approximately 3 kHz to 10 MHz). Enables easy comparison of EMI levels before and after installing dirty electricity filters. Features an audio function that allows you to listen to the electrical noise on a circuit and hear it diminish as filters are installed
