Main Technical Automation Functions

●Automatic calibration: automatically test "probe zero", "K value", "leading edge" and "material sound velocity";

●Automatically display defect echo position (depth d, level p, distance s, amplitude, equivalent dB, aperture ф value);

●Freely switch three kinds of scales (depth d, level p, distance s) to meet the requirements of different inspection standards and the ruler usage habits of inspection engineers;

●Auto gain: automatically adjust the waveform to 80% of the screen height, which greatly improves the inspection efficiency;

●Automatically record the flaw detection process and can perform dynamic playback, and the recording time is unlimited;

●Automatic Φ value calculation: straight probe forgings to detect flaws, identify defects * high waves automatically convert the aperture Φ value;

●Automatic DAC, AVG curve automatic generation of sampling points is not limited, and can be corrected and compensated to meet any flaw detection standards;

●Automatically analyze and display playback parameters, and automatically generate flaw detection reports;

Flaw Detection Function:

●Dynamic recording: detect real-time dynamic recording waveform, store, and replay;

●B-scan, real-time scan, scan the cross section of defects;

●Echo envelope: real-time retrieval and recording of defects * high waves;

●Calculation of Φ value: straight probe forgings flaw detection to find defects * high wave automatic conversion;

●Defect location: real-time display of level value L, depth value H, sound path value S;

●Defect quantitative: real-time display of SL, EL, GL, RL quantitative values;

●Real-time display of hole-shaped defects Φ value;

●Defect characterization: automatically display defect size and location;

● Real-time clock recording. Track record of real-time flaw detection date and time, and store it

●Control interface. High-speed USB and RS232 interfaces provide transmission and printing

Data Storage

●100 independent flaw detection channels, free to input any industry flaw detection standards, convenient storage and recall;

●3000 flaw detection waveforms and data can be stored, recalled, printed, communicated and transmitted with the computer;

screen protector

●The screen can be turned off or subtitles can be displayed in standby, saving power and prolonging the service life;
