GD-4133 Cable Fault Locator is used to measure distance between cable faults. It's easy to operate and with friendly interface.

It can be used alone under the low voltage pulse mode. Under the mode of pulse current, it needs to work with GD-2131 high voltage generator. Under the multiple pulse mode, GD-4133S coupler should be worked together. After distance locating, GD-4132 fault locator should be used for fault pinpointing. These products can be combined into a set of high performance and innovative cable fault testing system.

• 7inch LCD screen, friendly interface.
• Multiple distance locating method:
  Low voltage pulse method: it is suitable for 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.
  Pulse current method: It is suitable for distance measurement of the high resistance fault, breakdown fault. Using the current coupler to collect signals from the earth wire, it makes the user far away from the high voltage. This method is safe and reliable. 
  Multiple pulse: the advanced way to measure distance. The waveform is easy to identify and the accuracy is high.
• 200MHz real-time sampling. Max. 0.4m measurement resolution. It has small dead zone and is special for the short cable and near fault cable.
• Touch screen and press key operation
• PIP copy(pic. temporary storage)
  There will be a main window and three temporary storage windows could check three waveforms together.
• Built-in operating system
  Special software management for software upgrade, backup and restore.
• Scale function
  A starting point,10 contacts, one cable fault and one full length could be setting. 
  Display scale and testing waveform together
