Features and Advantages
1.Multiple distance locating method:
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.
Impulse current method: apply to the high resistance fault, breakdown fault. Use the current coupler to gather signal from the earth wire
Multiple impulse method: improvement of the SIM method
2.200MHz real-time sampling
Advance tech.Upgrading for SIM method
Max. 0.4m measurement resolution,ZC-700D has small blind zone and is special for the short cable and nearly-terminal fault cable
3.Touch screen and press key operation
Touch operating screen with smart gesture operation
Support cursor drag-drop function and double-click function,easy to locate
Simple function menus with high performance.
4.Big color LED screen, friendly interface
Simple function menus with high performance
5.7″ LED screen,160°viewing angle,bright with 750cd/m2 to view under sunshine
PIP copy（pic. temporary storage). There’ll be a main window and three temporary storage windows could check three waveform together.
6.Waveform storage and PC communication
