Peak Hold:
Automatically searching the peak wave inside the gate and hold it on the display.
Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter.
Continuous Record: Record the display continuously and save it to the memory inside the instrument.
Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance.
Defect Sizing: calculate the defect size
Defect Evaluation: Evaluate the defect by echo envelope.
DAC: Distance Amplitude Correction
AVG: Distance Gain Size curve function
Crack measure: Measure and calculate the crack depth
