Product introduction

NALGT cable fault detector is to cater to industrial-grade power industry solutions and IT era of rapid development, the original cable fault tester limitations, using industrial embedded computer platform systems, network services, USB communication technology systematic, very greatly improve the instruments functions and use value and convenient on-site environmental operations. Especially for the growing number of buried cable provides a unique data management software. The entire system meets national new power industry standard "DL/T849.1 ~ DL/T849.3-2004" special test equipment electrical equipment General technical conditions, the system is tested by the system host and the fault locator and meter three-part cable path for all kinds of power cable fault test, cable path, the depth of buried cables and cable testing archives to find the daily maintenance and management, as well as railways, airports and signal control cables, and streetlights accurate cable fault testing

Also called name 

Cable fault tester, high voltage cable fault tester, cable fault tester, pointing device, path analyzer, routing cable fault tester, cable fault Pursuit, portable cable fault location system, flash cable fault tester, cable fault sentinel, cable path analyzer

The Characteristics of the products

◆ The first use of industrial embedded computer platform system , industrial use of the environment , to achieve strong stability. Lithium-powered , convenient on-site testing.

◆ Chinas first 12.1-inch large-screen LCD , the entire computer XP operating platform integrated software , bid farewell to the era of cable tester chip and equipped with cable fault testing software and cable data management software.

◆ Using the latest USB communication interface , signal acquisition and stable, with a laptop computer can achieve dual control dual display , the host can automatically choose the lowest 6.25MHz, the sampling frequency up to 100MHz five kinds to meet the testing requirements of different cable lengths , reducing a rough measurement errors.

◆ Software fault auto search , close automatically, double cursor can be accurate to 0.15 meters , arbitrary waveform can be compressed , expanded , with the screen closer to the standard randomly display two waveforms for accurate comparison you analyze , improve test accuracy , reduce errors .

◆ Support for the latest launch of 3G communications terminal or wireless network card , a dedicated 3G software enables real-time testing expert remote site technical services, expert remote control hosts , giving users on-site testing to provide timely , accurate waveform analysis and exchange of guidance, so you worry work .
