AVG
【Note 1】: The AVG curves on this system are only applicable to round normal/straight-beam probes. 【Note 2】: The AVG curves are calculated based on theoretical formula, which is valid for the area beyond three times of near field only. It is a straight line in the area within three times of near field.
2.15.1 Making AVG Curves Operation: 1) Input probe frequency Press Config to go to Config main menu. Select the submenu AVG_Freq. and adjust it to the current probe frequency. 2) Input Probe Specification Press Config to go to Config main menu. Select the submenu AVG_Diam. and adjust it to the current probe diameter. 3) Press AVG to switch to AVG main menu. 4) Select the submenu AVG_Op and adjust it to Record. 5) Input Base_Diam. Base diameter refers to the flat bottom hole diameter of the reference test block or the workpiece in use. If Base_Diam. is set 0, it means that the reference test block or the workpiece has a 19
Shantou Institute of Ultrasonic Instruments Co., Ltd. broad flat bottom. 6) Input the flat-bottom hole equivalent diameters for the three AVG lines to be created. Select the submenu AVG_L1, AVG_L2 and AVG_L3 respectively and adjust their values. 7) Input Compensation Value When the echo amplitude of the reference test block or the workpiece does not comply with the theoretical value, compensation is required to compensate the value difference. This is a common practice when a broad flat bottom is used for reference. Because the broad flat bottom echo amplitude usually does not reach the theoretical difference of amplitude for the echo of the same-distance flat-bottom hole, if the broad flat bottom amplitude is used as a reference, the calculated flat-bottom equivalent value in actual testing will be inaccurate. Therefore, in situations when the broad flat bottom echo is used as a reference, it is recommended to input the error (between the actual difference of the reference broad flat-bottom echo amplitude and the flat-bottom test block amplitude with the same-distance, which can be calculated with the theoretical formula) as compensation. Input the compensation to bring the calculation more accurate. 8) Select the submenu GAStart. Adjust gate start position and hitch the gate to the echo to be recorded. Adjust gain or press AGC to bring the echo amplitude around 80%. Now the system will make the curves automatically. 9) If AVG curves display is not required, select Off in AVG_Op submenu to hide the current curves.

3.5 Store and Recall of System State and Testing Parameter The internal large memory of the system can store up to 300 groups of system test state data sets. Therefore system test state data of calibrated probes for different applications or specific to workpieces can be saved to records (datasets). Before testing, the corresponding saved records can be recalled. After releasing the freeze state, testing is available immediately. Thus toggle between different test states is very fast, which allows easy management and less complicated calibration on the system.
3.6 System Parameter Setup Specific to Testing 1) For large workpieces or coarse-crystal material testing or when high sensitivity is required, set Power at High and Damping at Low, so as to increase system test sensitivity. 2) For situations of thin workpiece testing or high resolution is required, set Power at Low and Damping at High, so as to increase system test resolution but the test sensitivity will decrease accordingly. When testing with a narrow-pulse probe, set Rectify at Pos. or Neg. to further increase resolution. 3) Usually PRF is set 6. 4) Determine system frequency setup based on the rated frequency of the selected probe. For a 2.5MHz probe, the test sensitivity surplus for the step 1~4MHz is the highest among the available frequency range. 5) Generally, Rej is set 0%.
3.7 Using Battery to Increase Anti-interference When the AC power grid receives strong interference, please use battery for power supply. The power supply from battery effectively cuts off interference signals from AC power grid, while other external interference signals will not easily affect the system.

Testing Application and Examples
4.1 Testing with A Normal Probe General testing steps with a normal probe: 1) Set up system initial parameters (Rng, Vel, Dly, PRF, Band, Power, Damping, Thk). 2) Correct system zero and velocity. Please refer to 2.12 Auto Correction. 3) Select either of the below items: (1)
Confirm the tested bottom echo or reference sensitivity, based on which increase
compensation sensitivity. (2)
Make AVG curves. Please refer to 2.15 AVG.
4) Set up the system test range and save the current system status to a blank dataset and record the dataset number. 5) In field testing, recall the test technique from the preset dataset (If necessary, adjust the scanning sensitivity) and start testing. 6) According to the echo position and amplitude shown up during testing (hitch the gate to the echo and read from the measurement data area), determine whether it is a defect echo and calculate its equivalent (If AVG curves are adopted, the flat-bottom hole equivalent to the echo amplitude can be read from the system measurement data area directly), and then process the workpiece based on the applicable standard.
4.2 Testing with An Angle Probe General testing steps with an angle probe: 1) Setup system initial parameters (Rng, Vel, Dly, PRF, Band, Power, Damping, Thk) 2) Correct system zero and velocity (usually only the system zero can be corrected). Please refer to 2.12 Auto Correction. 3) Use a ruler to measure the probe flank(X_Value)and input it in the system. 4) Input the probe nominal Angle or KValue (If the user is demanding on measurement result, the
33
Shantou Institute of Ultrasonic Instruments Co., Ltd. probe actual angle can be measured with the angle measurement function or a CSK IA test block. Please refer to 2.13 Angle Mesurement). 5) Use a standard test block (such as CSK IIIA) to make DAC curves, and set dB distance and workpiece surface compensation between the three DAC curves according to the applicable standard (such as JB/T 4730-2005, GB11345-1989). Please refer to 2.14 DAC. 6) Set up Rng for testing. Save the current system setup status and DAC curves to a blank dataset and record the dataset number. 7) In field testing, recall the test technique from the preset dataset (If necessary compensate the scanning sensitivity based on the current sensitivity) and start testing. 8) According to the echo position, amplitude shown up during testing and dB difference of DAC curves (hitch the gate to the echo and read from the measurement data area), determine whether it is a defect echo and calculate its equivalent, length and area.
4.3 Application Examples 4.3.1
Application Example of JB/T 4730-2005 Standard
Use a 2.5Z10×10K2 probe, as per JB/T 4730-2005 standard, to test the welding line of a 20mm-thick steel plate. The operating procedure is usually as follows: 1) Set up system initial parameters Set the submenu Coor (in Config main menu) at SPath; Set the submenu SPath (in Basic main menu) at 200mm; Set the submenu Vel (in Basic main menu) at 3230m/s; Set the submenu Dly (in Basic main menu) at 0mm; Set the submenu PRF (in Config main menu) at 6; Set the submenu Band (in Config main menu) at 1~4MHz; Set the submenu Power (in Config main menu) at High; Set the submenu Damping (in Config main menu) at Low; Set the submenu Thk (in Config main menu) at 100mm

When the reference echo amplitude at a deeper depth is less than 20% of screen display amplitude, increase system sensitivity (gain value) to increase echo amplitude, so as to easily record that echo reference point. (5)After recording the required echo reference points, a group of DAC curves are completed. As per JB/T 4730-2005 standard, the sensitivity of DAC_L3, DAC_L2 and DAC_L1 are: Φ1×6-9dB, Φ1×6-3dB and Φ1×6+5dB. Therefore the submenus DAC_L3, DAC_L2 and 35
Shantou Institute of Ultrasonic Instruments Co., Ltd. DAC_L1 (in DAC main menu) are set at: -9dB, -3dB and+5dB. In addition, the workpiece surface compensation is normally 4dB, Comp shall be set at 4dB. Set the submenu Line_Sel at DAC_L2. 5)
Set the submenu Thk (in Config main menu) as the thickness of the workpiece to be tested. In this specific example, the submenu Thk (in Config main menu) is set at 20mm. Save the current system setup status and DAC curves to a blank dataset and record the dataset number.
6)
In field testing, recall the made DAC curves from the submenu Dataset (in Store main menu). When a suspected echo appears within the DAC curve measurement range, hitch the gate to that echo. If the number displayed in the measurement data area HdB field is 5.5 (the number refers to the dB difference between the echo peak within the gate and the currently selected curve DAC_L2), the echo equivalent shall be:Φ1×6-3dB+5.5dB=Φ1×6+2.5dB, which belongs to Class 2 flaw.

(5)After testing, verification can be performed with a Φ3 hole at the depth of 20mm. 4) Make DAC Curves (1)Press DAC to go to DAC main menu. (2)Set the submenu DAC_Op at Record. (3)Use the measured probe to scan a Φ3 hole at the depth of 10mm on the RB-3 test block. Find the peak of the echo and hitch the gate to that echo. Adjust the echo height to around 80%. Press the confirm key
and the first echo reference point is recorded and the first
curve section is drawn. (4)Repeat step (2), and record the echoes of the holes from shallow to deep depth at 20mm, 30mm and 40mm. When the reference echo amplitude at a deeper depth is less than 20% of screen display amplitude, increase system sensitivity (gain value) to increase echo amplitude, so as to easily record that echo reference point (5)After recording the required echo reference points, a group of DAC curves are completed. As per Class B of GB 11345-1989 standard, the sensitivity of DAC_L3, DAC_L2 and DAC_L1 are: Φ3-16dB, Φ3-10dB, Φ3-4dB. Therefore the submenus DAC_L3, DAC_L2 and DAC_L1 are set at: -16dB, -10dB and -4dB. In addition, the workpiece surface 37
Shantou Institute of Ultrasonic Instruments Co., Ltd. compensation is normally 4dB, Comp shall be set at 4dB. Set the submenu Line_Sel at DAC_L2. 5) Set the submenu Thk (in Config main menu) as the thickness of the workpiece to be tested. In this specific example, the submenu Thk (in Config main menu) is set at 20mm. Save the current system setup status and DAC curves to a blank dataset and record the dataset number. 6) In field testing, recall the made DAC curves from submenu Dataset (in Store main menu). When a suspected echo appears within the DAC curve measurement range, hitch the gate to that echo. If the number displayed in the measurement data area HdB field is 5.5 (the number refers to the dB difference between the echo peak within the gate and the currently selected curve DAC_L2), the echo equivalent shall be: Φ3-10dB+5.5dB=Φ3-4.5dB, which belongs to Class 2 flaw.
