XHDD503
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.
