OPERATION AND FUNCTION INTRODUCTION
PCLD-904P support both the acoustic-magnetic synchronization pinpointing.
The acoustic-magnetic synchronization pinpointing support both intelligent pinpointing and waveform pinpointing. When use the intelligent pinpointing method, device will auto display the acoustic-magnetic delay value and when use the waveform pinpointing method, we need to make sure the cursor position and measure the delay value.

1. ACOUSTIC-MAGNETIC SYNCHRONIZATION INTERFACE AND FUNCTION

Principle:

Electromagnetic signal transmit by light speed and the time transmit from cable to the sensor could be ignore. The acoustic transmission speed is much lower only several hundred per second. So we can distinguish the faulty points distance by the time difference between magnetic signal and the acoustic signal.

There are two interfaces, intelligent pinpointing and waveform pinpointing interface when use the acoustic-magnetic pinpointing method. The intelligent pinpointing will display the acoustic-magnetic value by intelligent calculation method. It makes the pinpointing more easy and quicker, and need low requirement for the user.

Device also keep a traditional interface which more suitable for the profession staffs with experience. Then the user need to measure the acoustic-magnetic delay value by the cursor position. Refer below display interface:
