GM.700 Surge Wave Fault Pin-pointer

The GM.700 power cable fault pin-pointer 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.
