Introduction
 DC-310 portable cable breakdown tester adopts pulse reflection principle and modern microelectric technology, which is for testing the precise distance of the disconnection, mixed connection, and climate of the full-automatic local telephone cable. It also can help the position the breakdown of 112 testing station. The examining personnel can take it as a helpful tool to the position of the breakdown and to acceptance check when examining the electric characteristic.
Function
◎ portable design ; humanistic moderate interface ; easy to manipulate.
◎ Well intellectualized; the screen will show the characteristic of the breakdowns and their distance with a easy click of the test key.
◎ DAGC(Data Automatic Growing Control)System: Full-automatic data growing adjustment.
◎ Technology of Identifying the indistincted waves form: automatic identification; leaving no unmeasured area .
◎ Cell with huge capacity; no memory effect; protective charge
