Full screen display function: make the echo display area cover the whole screen, bringing maximum visual feeling to the work.
Mass storage: can store up to 1000 data sets, including waveforms, curves, parameters, etc. (including 1000 channels in the traditional sense)
Measuring point: peak value or front edge of echo in valve
Echo-echo thickness measurement: Zero calibration is omitted, and the net thickness of the substrate can be directly measured through the coating.
Peak memory: real-time envelope displays the highest wave of the defect and records the maximum value of the defect, which is helpful for accurate location and fast scanning of the defect, and can also help to identify the defect by means of envelope waveform.
Automatic gain: automatically adjust the gain to the set amplitude height
Alarm function: incoming/lost wave alarm
Solid waveform display: increase visual contrast of waveform, fast scanning is not missing
Real-time clock: automatically recording the date and time of the stored waveform
Display freezing: capture waveform and acoustic range data at any time, and move the valve to measure echo parameters after freezing.
Defect location: real-time display of sound path S, level X, depth Y and wave height H.
Defect quantification: real-time display of dB difference value and SL quantification value
Digital suppression: 0-80%, increasing by 1%, without affecting linearity and gain
Valves a and b: two independent measuring valves to monitor echo, amplitude and acoustic distance
DAC, AVG curve function, curve changes with the change of gain, sound path and displacement
Distance compensation: Real-time compensation of flaw detection echo according to time-varying gain method to avoid missing small defects
Center value calculation: automatically convert the echo height of the defect into the equivalent size of the defect
Variable emission pulse generator: the pulse voltage is continuously adjustable from 50 to 400 volts and the pulse width is continuously adjustable from 25 to 1000 seconds
Impedance matching: 33/50/100/500 ohm adjustable for four gears.  
Receiving filter: 1-4MHz, 0.5-15MHz adjustable.
Multi-step adjustable repetition frequency: avoid reverberation (phantom) signals when detecting large workpieces.
Working languages: Chinese and English operating interfaces
Data communication: communicate with the computer through RS232 interface to transmit waveforms and data, so as to realize the management of deep injury results, the generation and printout of flaw detection reports on the computer.
