XHDD503 is a classic portable underground cable fault pinpointer independently developed and produced by our company. After more than 50 years of precipitation, the acoustic-magnetic synchronization detection technology it adopts has become very mature and widely accepted and recognized by users in the industry.
The XHDD503 cable fault locator is very small and light, it is packed in a protective PVC case, easy to carry after the user finished detection.
The XHDD503 power cable fault pinpointer is designed with a microammeter display, with electrical level adjustment, frequency adjustment and volume adjustment knobs.
By observing the swing of pointer on the microammeter, you can see the magnetic field strength during the flashover discharge at the fault point. Rotate the electrical level knob to adjust the reference of the magnetic field strength. In the process of path detection, adjusting the receiving frequency can make our ears hear the path signal that is easier to identify. Adjusting the frequency knob during the process of fault location can effectively avoid the radio signal. Adjust the volume during cable fault location and cable path finding, so that our ears hear a more appropriate sound signal.

Product Features
1. Synchronously receive vibration waves, sound waves and electromagnetic waves generated during discharge at the fault point;
2. The acoustic and magnetic channels are designed separately and powered separately, with stronger anti-interference ability;
3. Super magnification, detection depth is greater than 10 meters;
4. Ultra-low and low-power design, quiescent current is less than 10mA, and continuous operation is more than 20 hours;
5. Analog meter design, signal strength and trend are clear at a glance;
6. Zero level can be adjusted arbitrarily, suitable for various strong and weak scenes.
1. Pointer meter: indicates the magnetic field strength during flashover discharge at the fault point;
2. Volume adjustment: adjust at fixed point and path so that our ears can hear more appropriate sound signals;
3. Working mode: select working mode (off, fixed point, path);
4. Frequency adjustment: adjust the receiving frequency during path detection so that our ears can hear more easily identifiable path signals. Adjustment at fixed point can effectively avoid radio signals;
5. Level adjustment: adjust the benchmark of magnetic field strength so that the meter head can swing effectively;
1. Input channel: connect to the probe sensor for precise positioning (connect to the probe sensor for path detection);
2. Output channel: connect to dedicated headphones.
