MEWOI-CD760 cable fault locator,POWER CABLE FAULT PRELOCATOR,Cable fault rangefinder
Overview
The CD-760 Power Cable Fault locator is an easy operation device used for distance locating . It ’ s easy to operate,support both touch screen/button operation and with friendly interface. Low voltage pulse mode (TDR ) can be used independently; In impulse current mode (ICM), it needs to be used with CD-6XX series high voltage signal generator; In the multiple impulse mode(MIM) must also be tested with CD-7505 cable multiple impulse filter coordination; After the distance measurement is completed, the CD-8XX series digital multifunctional cable fault pin-pointer shall be used for accurate point pinpointing. Together, they form a high-performance cable fault finding system that offers a variety of innovative features. |
Features
Multiple distance locating method:1,Low current impulse method: apply to the locating of the low resistance fault. Short circuit fault, open circuit fault. It also can be used in the measurement of the cable length, the intermediate joints, T joints, and cable termination joint. This method also can be used to correct the wave velocity. 2,Impulse current method: apply to the high resistance fault, breakdown fault. Use the current coupler to gather signal from the earth wire 3,Multiple impulse method: improvement of the SIM method.Waveform is clear and easy to identify, high ranging accuracy. 400MHz real-time sampling1,Advance tech.Upgrading for SIM method 2,Max. 0.1m measurement resolution,CD-760 has small blind zone and is special for the short cable and nearly-terminal fault cable Auto measurement function1,Automatic selection of appropriate range and gain, given fault location, easier testing. 2,Only low voltage pulse mode supports this mode. Automatic calibration function1,Automatically analyze the characteristic waveform of the fault waveform and display the possible fault location . 2,Only low voltage pulse mode (TDR) supports this mode. Enhance the picture-in-picture temporary comparison function1,PIP copy （ pic. temporary storage). There'll be a main window and three temporary storage windows could check three waveform at same time. 2,Support low-voltage pulse and pulse current waveform comparison function, fault distance multi-direction verification, more accurate judgment. Overall display function1,When the waveform zoom, the overall waveform is displayed at the same time, which is more convenient for calibration and ranging. Touch screen and press key operation1,Touch operating screen with smart gesture operation 2,Support cursor drag-drop function and double-click function,easy to locate Big color LED screen, friendly interface1,Waveform clear, especially in the multiple impulse test,multiple waveform using different colors, easier to identify 2, 8" LED screen,bright with 1500cd/m2 to view under sunshine 3,Support automatic backlight brightness adjustment function Waveform storage and PC communication1,A large number of waveforms can be stored in the machine 2,Use USB disk to export waveform data 3,Waveform storage and communication with computer. 4,Provide computer background management software to manage data dumped by U disk or online data. Power management1,Back light weakens if no operation in 1 min and power off in 30 min. if no operation. 2,When the battery is under voltage, the instrument will automatically shut down to protect the battery. 3,Built-in Polymer Lithium-ion battery. 4,Working time could reach 10 hours for each use. Solid case, light and portable. |
