8. After freezing, the full range can be adjusted; the relative gain zero key; the search sensitivity increase key; the oblique probe flaw detection distance in the X and Y directions; the delay rapid return to zero key; the curve position prompt function and so on.
7. With high-speed automatic height function, the instrument will automatically change the gain after pressing the key to make the echo height reach the specified value.
6. With dynamic waveform drawing function, it can draw dynamic waveform curve (the relationship between the position of the moving probe and the height of the echo), which is convenient for analyzing the nature of the defect, and draws a trace of the echo peak point in real time. Distance, according to the shape of the curve, can help analyze the nature of the defect.
5. With waveform expansion function, the expansion degree has nothing to do with the width of the entrance gate, and the expansion degree can be continuously changed arbitrarily.
4. With interface wave lock function, liquid immersion method can be used for flaw detection or thickness measurement.
3. Use left and right split screen display mode of echo display area.
2. It is very convenient to estimate the echo distance by using the variable division scale technology.
1. Power saving, power consumption is only 2 watts, 4 No. 5 Ni-MH batteries, 2500mAh, can work for 5 to 6.5 hours after charging. Features
