Memory

The instrument has a built-in large-capacity memory, and data and files will not be lost due to power failure of the instrument.

Memory of 500 channel files to store calibration setups and probe parameter.

Memory of 1000 wave report files to store A-Scan wave and settings.

All the files can be stored, recalled and cleared.

The channel settings and report files can be exported via U disk, and the information can also be stored in unlimited amounts via USB memory

Video Recorder

Video Recorder is useful in many situations, it is very convenient for those who want to analyze the probing activities later.

The instrument can record the test process and save it as a video file, which can be played back through the instrument or special software. It supports up to 10 video files, and each video file can be up to 5 minutes long.

If you choose to save the video file to the U disk, the number and duration of the video file will not be limited.

Recording and replaying the testing process provides great convenience for future study and analysis of flaw detection.

Video playback supports pause, fast forward, fast rewind, and stop functions.

Functions

 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.

 AWS D1.1. Choosing this standard can reduce manual calculations and improve detection efficiency.

 Curved Surface Correction feature.

 Crack Height Measure function.

 Gate Magnify ：spreading of the gate range over the entire screen width.

 Video Recording and playback.

 Auto-gain function

 Envelope: Simultaneous display of live A-scan at 60 Hz update rate and envelope of A-scan display

 Peak Hold: Compare frozen peak waveforms to live A-Scans to easily interpret test results.

 Peak mark: capture and mark the peak in real time

 Echo coding: display 1~9 echo display area in different colors, used to analyze the defect position.

 A Scan Freeze：Display freeze holds waveform and test distance data.

 B Scan display feature. Intuitively display the defect shape of the workpiece and the detection result is more intuitive.
