2.9 AngleC (Angle Calibration) AngleC is for measuring the angle of an angle probe with a reflector (e.g. side drilled hole) with known size and depth. 【Note】 (1) To ensure measurement accuracy, auto calibration is required before angle measurement. See 2.7. (2) When performing angle measurement, the sound path between the probe and the reflection hole shall be greater than 2 times of NFL, so as to avoid measure result error due to the impact of near field area. Example condition: (1) The calibration block is as shown in Fig. 2-11, ReflDep 30mm, ReflApe 50mm.

2.12 Curve_AVG In the actual ultrasonic testing, due to different shapes and nature of defects, it is difficult to determine the real size of the defect. Therefore using "equivalent method" may quantify the defects. The equivalent method is a method of determining the size of the defect, as compared with the artificial defect of regular shapes, that is, when the perceived defect wave height is equal to the artificial defect wave height under the same testing condition, the size of the artificial defect is called the equivalent size of the defect. The artificial defect usually used to represent the equivalent size is FBH (flat bottom hole). For the regular reflector (including artificial defects), under certain assumptions, the relationship between the echo sound path, the amplitude (dB) and the defect equivalent can be expressed in a regular way that is called the AVG (DGS) curve, which is typically used for the area equivalent calculation of the defect for forging. Where A represents the distance in the unit of NFL; V represents the amplitude in the unit of dB, with the initial wave height 0 dB, and G is the defect equivalent, in the unit of probe size. AVG Curve is to guide the user to make AVG curves according to the test requirements. Example condition: (1) The test block is a 100-Φ2 forging block, i.e. Thickness 100mm, FBH Φ2. (2) The probe is a normal (straight-beam) probe with frequency 2.5MHz, diameter 20.0mm. Operation: (1) To ensure the accuracy of curve making, auto calibration is required before making the curve. See 2.7. . (2) In “Curve”, set up “MakeType” as AVG. 2-41

Adjust “Start” menu, or Gate key to adjust quickly (see 2.5.2), enabling the gate to record the echo. Move the probe to get the peak of FBH, then press Right or Enter key in “Record” menu to finish AVGCurve, as shown in the figure.

Fig. 2-20 AVG

2.13 CurveCtrl_AVG 2.13.1 Comp If the echo amplitude of the test block in use or the workpiece does not comply with the theoretical value, Adjust “Comp” menu to compensate the difference, which is commonly used in case that BW echo serves as the base. Since BW echo amplitude usually cannot reach the theoretical difference with the FBH echo amplitude of the same distance, taking the BW amplitude as the base will result in incorrect FBH equivalent calculated in practical testing. Therefore, in the situation that BW echo is used as the base, to make the calculation more accurate, it is suggested to use the error between the actual difference [of base BW echo amplitude and the echo amplitude of FBH test block of the same distance (different distance theory)] and the theoretical difference as a compensation value input. 2.13.2 Unit dB When the "Unit dB" function is turned off, the AVG curve position is set according to the equivalent value (mm/ inch); when the "Unit dB" function is turned on, the base line is 0dB. Set up ±dB value of AVG curve relative to the baseline. 2-43

Adjust Gate A to record the first bottom wave (by ensuring the measurement position in the gate is the peak position of the correct first bottom wave, which can be determined by adjusting aStart and aWidth, and the position of the inverted triangle in the gate line), According to the peak position in gate A, bStart is shifted automatically in proportion to record the second bottom wave. The difference of the peak in gate B and the peak in gate A is the thickness value of Echo to Echo (also by ensuring the measurement position in gate B is the peak position of the correct second bottom wave, which can be determined by adjusting bStart and bWidth, and the position of the inverted triangle in the gate line). ECHOMode is suitable for fast measurement of B1-B2 with different thickness. When adjusting the position 2 gates for manual measurement is required, use CoatMode. By adjusting the Start and Width of the two gates, the Bm-Bn value (such as B2-B3, or B3-B4) is measured.

Thickness Gauge (TG)

Fig. 3-4 ECHOMode Operation: (1) In Probe menu, set up PrbSel, PrbDly and MtVel. Generally, perform CalibZero for the known material velocity in Probe menu of StdMode. If required, perform CalibZero in this menu again, and then enter the measurement state. (2) In Gate menu, adjust the gate position, set up measurement parameters and turn on the over-limit alarm function. (3) In Meas menu, set up Rectify and AutoSrch. (4) To enable over limit alarm, set up in Alarm menu. (5) To save the measurement data file, set up in DataSave menu. 3.4.4 Issues Related to WorkMode (1) The measured waveform amplitude or gate should be adjusted according to the measurement requirements for each mode, enabling the signal at the measured position exceeding gate thresh and ensuring measurement accuracy. If AutoSrch or AGC cannot be achieved, please cancel the automatic function and use 3-29

manual adjustment. (2) For CoatMode or ECHOMode, it is recommended to use a

broadband-

frequency narrow-pulse probe (i.e. less signal pulse cycles, for example the dual probe 5M10FG-HL00 or 7.5M6FG-HL00, the delay series of single probes) for testing, so as to achieve the optimal measurement accuracy and stable measurement reading. For the general wide-pulse dual probe, ensure the cursor position in the 2 gates corresponds to signal in the 2 gates and better measurement accuracy. You may manually adjust the gate start, width and thresh of the 2 gates to properly locate the measurement position. (3) If Rectify is RF, and GateThresh is default to negative, it measures the negative waveform signal (below the baseline). The StdMode measurements correspond to the first peak of negative signal in the gate exceeding gate thresh. The zerocrossing after the peak is stable, which is conducive to stable display of measurements. If GateThresh is set Positive, i.e. it measures the positive waveform signal (above the baseline). The measurements correspond to the first peak of positive signal in the gate exceeding gate thresh. Due to the weak peak signal, the zero-crossing after the peak is not stable, which is not conducive to stable display of measurements. Generally it is suggested to set RF (GateThresh is set Neg) or Neg for Rectify, so as to get the most stable measurements displayed.

3.5 VelMeas Subject to the selected WorkMode, the material velocity is calculated and displayed based on the known Thickness. This function is for velocity measurement of a single-layer workpiece. For the velocity measurement of a multi-layer workpiece, use MultiMode. Before exiting VelMeas, choose whether to apply the velocity measurement to the current material. Operation:

3-30

Thickness Gauge (TG)

(1) In Probe menu, set up WorkMode, PrbSel, PrbDly and the known thickness. If required, perform CalibZero, and enter the measurement state. (2) In Gate menu, adjust the gate position and set up the measurement parameters. (3) In Meas menu, set up Rectify and AutoSrch. (4) To enable over limit alarm, set up in Alarm menu. (5) To save the measurement data file, set up in DataSave menu.

3.6 MultiMode If the workpiece has multilayer materials which are linked closely, you can use MultMode to measure, provided that the material velocity for each layer is known. The actual measurement effect is dependent on the multi-layer material. If the thickness for each layer is known, the velocity for each layer can also be measured. For MultMode measurement, choose whether to apply the velocity measurement of the measurement to the current material. For MultMode measurement, up to 4 layers can be measured at the same time. There are 4 measurement gates L1, L2, L3, L4 in total. The measurement for the 1st layer is the sound path difference between the first wave peak in gate L1 to zero; The measurement for the 2nd layer is the sound path difference between the first wave peak in gate L2 and L1; The measurement for the 3rd layer is the sound path difference between the first wave peak in gate L3 and L2; and the measurement for the 4th layer is the sound path difference between the first wave peak in gate L4 and L3. (The description example above takes Peak as "MeasPnt". In the practice, you may also set it as JFlank, the measure value at the intersection of the gate and the first wave. ) The main reading display for MultMode is the sum of layer measurements, with the measurement for each layer displayed on the right of main reading. For the measurement screen in MultiMode, see Fig. 3-5 .

3.10 V-PATH All the original dual probes have a set of default V-PATH calibration curves. Users can make a set of UserVpath curves for a specific probe. Generally you need to identify whether it is StdMode, CoatModeor or ECHOMode, and then make the UserVpath for that WorkMode. CoatMode and ECHOModee may share the same V-PATH curve. Select "VpathSel" in the menu to bring up the select screen. The VPATH curve for the current WorkMode of the probe in use is displayed on the left, and the Basic information such as Type; PntNum; point attributes of the selected curve is displayed on the right. Follow the tip to operate.

3.11 Auto Search and Auto Gain Control 3.11.1 AutoSearch (AutoSrch) AutoSrch function may search and adjust waves quickly based on the received wave signals. According to the wave signals of the tested thickness, AutoSrch quickly adjusts the system automatically, including the adjustment of DspDly, Range, Gain and the measurement gate. It provides a shortcut for operation. However, AutoSrch cannot 3-36

Thickness Gauge (TG)

completely replace manual adjustment, which is subject to probe selection, workpiece material, thickness and surface condition. If AutoSrch cannot capture and measure properly, please turn off AutoSrch and use manual adjustment for measurement. If the probe type is Dual, in StdMode, CoatMode or WorkMode, AutoSrch shall include auto adjustment of searching waves, range, gain and gates. If WorkMode is StdMode, the software search will bring gate A to record the first wave and adjust AGC of the first peak to 80%. If the workmode is CoatMode or ECHOMode, the software search will bring gate A to record the first wave and adjust AGC of the first peak to 80%, and gate B automatically records the second wave. AutoSrch in MultiMode and B-Scan is equivalent to auto gain A only. If the probe type is Single, AutoSrch in all work modes is equivalent to auto gain A only. AutoSrch can be set Single auto search, i.e. to auto search once if enabled once, or Continue (continuous) monitoring and search. The maximum gain auto adjustment of AutoSrch is bound by the set value of “MaxSGain“. If “MaxSGain“ is set too high, it may result in searching abnormal noise signals; If “MaxSGain“ is set too low, it may result in the desired signals not measured. The specific setup value shall be adjusted subject to the probe and workpiece. If in CoatMode or ECHOMode, the AutoSrch algorithm is also restricted by the impact of “Coat Status” parameter in “Meas” menu. “Coat Status” includes “Thin” and “Thick”. When the system is in calculating GateB position, it will refer to this parameter to adjust the algorithm, so as to better demonstrate and position gate B to the secondary beam position. 【Note】" Coat Status " is suggested to set as below: set to “Thin” if the coat thickness is less than or equal to 0.5mm, otherwise set to "thick". Operation: Select “Continue” or “Single” or “Off” in "AutoSrch" of Meas menu, or press the hot key F1or F2 (when the hot key is defined as AutoSrch), to enable or disable this function. 3.11.2 Auto Gain Control (AGC) If AGC is enabled, select to perform auto gain control for gate A or gate B (for CoatMode and ECHOMode only). For StdMode, the first peak amplitude in gate A is automatically adjusted to 80% height; For CoatMode and ECHOMode, the maximum peak amplitude in the selected gate is automatically adjusted to 80% height. AGC and AutoSrch functions cannot be enabled at the same time. The maximum gain auto adjustment of AGC is bound by the set value of MaxSGain. Operation:
