  • Page 25 3.4 DAC function Group Implement MENU Key--->>Select the "DAC" icon Hot key Explanation: Distance Amplitude Curve (DAC) function DAC is a curve that describes the relationship between the distance from the reflection point to the wave source, the echo height, and the equivalent size. Defects of the same size have different echo heights due to different distances.
  • Page 26 First input the probe frequency correctly, then calibrate the probe zero point, sound velocity and angle, and then enter the DAC curve build wizard. DAC Curve points are typically taken from a standard with equally sized reflectors (holes) located at various material depths. The primary echo from each of these points (for up to a total of 16 echoes) are recorded.
  • Page 27 Step 1:DAC Set On Step 2: Perform DAC build Enter the maximum depth of the test block as prompted by the display screen. The height of the test block for CSK-3A is 150mm.

  • Page 30 Echo Evaluation with DAC In order to be able to evaluate a flaw indication by means of the DAC, certain conditions must be met. The DAC curve must already be recorded. It only applies to the same probe that was used when recording the curve. Not even another probe of the same type must be used.
  • Page 31 AVG Function Group Implement MENU Key--->>Select the "AVG" icon Hot key Explanation: Using the AVG (the same as DGS) function, you can compare the reflecting power of a natural flaw in the test object with that of a theoretical flaw (circular disk-shaped equivalent reflector) at the same depth.
  • Page 32 First input the probe frequency correctly, then calibrate the probe zero point, sound velocity and angle, and then enter the AVG curve build wizard. Take 2.5M Straight probe and CSK-1-5 test block as an example to make AVG curve. Step 1:AVG Set On Step 2: Perform AVG build Before using the AVG feature to evaluate reflectors in test pieces, the characteristics of the attached probe must be specified, certain characteristics...
  • Page 33 Step 3: Couple the probe to the CSK-1-5 standard test block , capture the reference flaw so that its reflected echo is displayed on the instrument’s A-Scan, and adjust selected Gate’s starting point to ensure that the resulting echo triggers the gate. Step 4: Adjust the gain until the reference flaw’s A-Scan peak measures 60% of FSH (Full Screen Height).

After the detection range changes, the echo position displayed on the screen will change accordingly.
  • Page 36 The material sound velocity is divided into longitudinal wave sound velocity and transverse wave sound velocity. Straight probe uses longitudinal wave flaw detection, and angle probe uses transverse wave flaw detection. When the speed of velocity changes, the maximum detection range also changes.
  • Page 37 The thickness of the detected object is an important input parameter for the calculation of the number of echoes. thickness Limit 1mm ~ 1000mm Diameter of the detected object can be set only when the Curved correction to an inner surface or an outer surface. for example when testing longitudinally welded tubes.

Inside the instrument, the ultrasonic transmitter circuit generates a large electric voltage pulse and sends it to the ultrasonic probe, which stimulates the probe to emit ultrasonic pulses and enter the material to be inspected.
  • Page 45 When the scanning speed is faster, a higher repetition frequency should be selected to prevent the defect from being missed; when the scanning speed is slow, setting a lower emission repetition frequency can reduce the power consumption of the instrument. Range: 20Hz ~ 2000Hz, general setting (30~200) Hz.
