Abstract
LA INVENCION SE REFIERE A EQUIPOS DE PRUEBA PARA LA ELIMINACION DE PERTURBACIONES DE CONEXIONES DE ABONADOS QUE DEBEN PODER AVERIGUAR ENTRE OTRAS COSAS TANTO LA CAPACIDAD DE MAGNITUD O TAMAÑO CARACTERISTICA COMO LA RESISTENCIA DE LA CONDUCCION DE CONEXION DEL ABONADO DE FORMA LIBRE DE PERTURBACIONES. SEGUN LA INVENCION SE REALIZAN RESPECTIVAMENTE DOS MEDIDAS PARA LA DETERMINACION DE UNA MAGNITUD CARACTERISTICA.
