Display mode

Point/line/fading can display the maximum crack depth and show the crack depth in real time

Probe calibration

It has the function of displaying the waveform of the fundamental frequency signal before detection with scale marks. It has the function of sensor self-diagnosis

Bidirectional gain ratio(Y/X)

0.1 to 10/0.1 to 10, where X and Y can be set separately

Calibration curve

Defect depth (thickness) - amplitude /Y amplitude/phase curve calibration function

Extended function

Replay, analyze and save the eddy current detection signal

Data analysis

Automatically generate inspection reports, including inspection information, defect signals, location, date, personnel and other inspection parameters

Data recording and management

1.The system can save the impedance time base diagram of local defect signals, the waveform file of defect signals, and the corresponding parameter configuration during testing.

2. The system can save and replay the data of each detection waveform in real time, and analyze the saved signal waveforms.

3. The system is equipped with a memory card, which can bring the on-site detection data back to the laboratory for analysis, facilitating storage.

Human-computer interaction

The system can manually separate and classify signals to obtain characteristic parameters such as amplitude and phase of different types of signals.

2. The system can manually revise the phase offset of different signals.

3. The system has the function of calibrating the amplitude of the standard sample signal.

4. The system can set the duration of data collection.
