2. Acoustic and magnetic synchronization background noise reduction mode (BNR).
3. Bar graph indication of sound signal strength, adjustable sound trigger threshold
4. Bar graph indication of electromagnetic signal strength, adjustable magnetic field trigger threshold, with magnetic field trigger prompt function.
5. Acoustic-magnetic time difference method positioning mode: waveform display, the maximum acoustic -magnetic time difference is 80ms, which can be automatically calculated and manually analyzed; it has the ability to record the last acoustic -magnetic time difference.
Purpose Acoustic-magnetic synchronous pointing instrument, used in conjunction with high-voltage signal generators, is a portable and intelligent power cable fault precise positioning device.
It integrates acoustic-magnetic time difference positioning technology, noise reduction technology, path auxiliary testing and other technologies. The test mode and rich and varied prompt information can complete the cable fault location efficiently, accurately and pleasantly, which is an essential tool for emergency repair of power cable faults.
Packed with portable PVC protective case, beautiful, easy for carring, light weight, the protection level is not lower than IP54.
1.Using the acoustic -magnetic synchronous positioning technology to automatically calculate the acoustic -magnetic time difference and reduce the dependence on sound monitoring.
2.Background noise reduction technology can effectively filter out environmental interference noise and highlight the discharge sound at the fault location.
3.Combining the traditional acoustic measurement method and the advanced acoustic -magnetic method, the operator can choose freely according to the usage habits.
4.The gain value and trigger value of the acoustic signal and the magnetic signal can be adjusted manually, which is more convenient for fixed point.
5.The parameters are adjustable, select the appropriate filter parameters to suppress the environmental noise.
6.5-inch touch highlight LCD, ensure visibility in sunlight.
7.Powered by built-in high-capacity lithium-ion battery with fast charger.
8.Small and portable, light weight.
There are display areas for acoustic waves and magnetic waves on the screen, and the time difference between the two is displayed on the right. Acoustic-magnetic synchronization method is used to accurately measure cable fault points, making detection easier and faster.
