Functions:
- Flaw detection standard: Built-in common flaw detection standards, direct call, convenient and fast.
- Auto calibration: Automated calibration of probe zero offset, probe angle (K value) and material velocity.
- Flaw Locating：Live display Sound-path, Projection (surface distance), Depth, Amplitude,
- Flaw sizing: Automatic flaw sizing using AVG or DAC, speeds reporting of defect acceptance or rejection.
- Digital Readout and Trig. Function: Thickness/Depth can be displayed in digital readout when using a normal probe and Surface Distance and Depth are directly displayed when angle probe is in use.
- DAC/AVG: The curve is automatically generated, and the sampling points can be compensated and corrected. The curve automatically floats with the gain, automatically expands with the detection distance, and automatically moves with the delay time. It can display the AVG curve of any aperture.
