摘要

Electronic apparatus for integrity testing electrical and cable length of industrial networks of digital communication, the so-called fieldbus.Assembled with or without connectors. Characterizes the invention an electronic partum to instantly test and measure the electrical integrity and the length of cables for digital communication networksThe so-called fieldbus or industrial networks in real time.Through technique that also characterizes the invention based on concurrent and subsequent measurement combined analysis of three electrical properties of the system under test: electrical resistance.Electrical capacitance and electrical inductance.Such electronic apparatus operates within a portable instrument and manual, battery powered,And equipped with a touch screen keyboard and a liquid crystal display graphics backlit messages and user interface that also characterizes the invention.
