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.
