Located and isolated power for my computer. now My network is good averaging between 75gb to 150gb with 5g internet. before I was getting about 20gb or worse.

My house is over 90 years old and the mains power in it is very dirty. So dirty that the music playback was ruined by the high noise floor for any of my audio devices, unless an audio-grade line conditioner was used. But the new meter showed a rather low reading of around 40 for the wall outlets in the house. Does that mean the line power is actually clean and all my devices have malfunctioned? More confusingly, the meter showed a higher reading between 60-100 for the line conditioners I used. Does that mean the power from these line conditioners' outlets is dirtier?

Funciona muy bien capta hasta una emisora de radio en el vecindario. Función de medida muy básico, medida del ruido eléctrico y nada más, pero su precio es elevado. Después que se corrige el ruido se va al estante a dormir, por lo que pensaría en de una poner filtros y listo ahorro la inversión. Cómo equipo de instalador profesional si es muy útil, para el hogar un simple radio en am en la banda libre nos muestra también el ruido permanente en la instalación electrica. Y con filtros EMI podremos oír la atenuación del mismo con la radio AM
