Functional features:
Background noise reduction technology can effectively filter out the environmental interference noise and highlight the discharge sound at fault location.
The intelligent fixed-point method can directly give the acoustic magnetic delay value through the intelligent algorithm, which reduces the requirements for testers.
Automatic mute function, automatic mute when moving the sensor, avoid the noise of the mobile sensor and damage the ear.
The function of the electronic compass shows the direction and direction of the cable laying. Simultaneous interpreting of the position and angle of the sensor.
The filter parameters of sound channel can be adjusted to select appropriate filter parameters to suppress environmental noise.
Automatic gain function, magnetic field trigger gain automatic adjustment, more convenient fixed point.
