2.11 2.11

Aut oSearch oSearch and FloatingGain FloatingGain Functio ns

2.11.1 2.11.1 Aut oSearch When using dual-element probe , with this function quick waveform search and adjustment can be carried out subject to waveform signals received. The AutoSearch function provides a shortcut for quick system adjustment and then performs measurement based on the waveform signals of the measured thickness. Such function includes: adjusting DisplayDelay, Range, Gain and gate measurement. However, AutoSearch cannot replace manual adjustment completely, which is also subject to probe selection, as well as material, thickness and surface status of work piece. If AutoSearch function can not achieve proper capture for measurement, please turn off the AutoSearch function, but adjust manually for measurement. Operation: When using dual-element probe, turn on the Au to Searc h function in the MEAS MEAS main menu, or press

(provided

is defined as Au as Au to Searc h ) to activate the function.

When WorkMode is WorkMode is Normal, Normal , through search by the software, bring gate A to record the first echo, and increase autogain of the first peak of the echo to 80%. When WorkMode is Thru-Coating, Thru-Coating, through search by the software, bring gate A to record the first echo, and increase the autogain of the max. Echo peak to 80%, and gate B will auto record the second echo.

16


【Note】:

1.

When using single-element probe, AutoSearch probe, AutoSearch function in Normal and Through-Coating Through -Coating work modes can only have gain automatic adjustment within gate A.

2.

When EchoToEchoMode EchoToEchoMode is selected, the AutoSearch function is disabled. The gain automatic adjustment can only work by FloatingGain function.

3.

The AutoSearch function is default to auto search continuously after bootup. It can be set to auto search once, that is to run auto search once only upon each bootup. Select Au to Searc h from the main menu MEAS, MEAS, press the shift button between Continue and One. One . Press

2.11. 2.11. 2

or

， and toggle

to switch between start or stop.

Floatin gGain

When FloatingGain is on, gate A or gate B can perform FloatingGain function (only for ThruCoating mode and EchoToEchoMode). When WorkMode is Normal, the system will automatically bring the first wave peak amplitude within gate A to 80% height. When WorkMode is Thru-Coating mode or EchoToEchoMode, the system will automatically bring the highest wave peak amplitude within selected gate to 80% height. This function can not be activated with AutoSearch function at the same time. 【Note】: When AutoSearch or FloatingGain is on, the maximum value of self-adjusting gain

is

limited by the MaxSearchGain. By adjusting this set value, users can define the

maximum value of self-adjusting gain. If this value is set too high, it may search the clutter signal. If this value is set too low, it may not search the desired signal. Specific settings need to be adjusted based on factors such as probe and workpiece.

2.12

WorkMode

There are three work modes for selection: Normal, Thru-Coating and EchoToEchoMode. EchoToEchoMode. a)

When WorkMode is Normal, Normal , the measurement reading is the measurement value between the display zero and the zero-crossing before the first peak higher than GAThresh (the position is auto tracked by the small upside down triangular symbol). See Fig. a below.

b)

When WorkMode is Thru-Coating, Thru-Coating, the measurement reading is the measurement value 17


between the zero-crossing before the highest peak higher than GAThresh (the position is auto tracked by the small upside down triangular symbol) and the zero-crossing before the highest peak higher than GBThresh. See Fig. b as below. c)

When WorkMode is EchoToEchoMode is EchoToEchoMode,, the measurement reading is the measurement value between the zero-crossing before the highest peak higher than GAThresh (the position is auto tracked by the small upside down triangular symbol) and the zerocrossing before the highest peak higher than GBThresh. See Fig. c as below. In EchoToEchoMode, gate A is the triggered gate. Adjust gate A to hitch the first bottom wave (It is neccessary to make sure that the measuring position within the gate is the correct highest wave peak position of the first bottom beam. It can be judged by adjusting gate start, gate width and the small upside down triangular symbol.) The system will automatically move the GBStart in proportion to make gate B cover the second bottom wave based on the highest peak position within gate A. The difference between highest peak within gate B and gate A is the thickness of Echo to Echo (It is necessary to make sure that the measuring position within the gate B is the correct highest wave peak position of the second bottom beam. It can be judged by adjusting GBWidth and the small upside down triangular symbol. ). EchoToEchoMode is suitable for quick measurement of different thickness by B1-B2. When it is necessary to arbitrarily adjust two gate positions to have manual measurement, please use Thru-Coating mode to adjust the start and width of both gates and measure required Bm-Bn (e.g. B2-B3, or B3-B4) value.

【Note】:

1.

Adjust the measured waveform amplitude or gate based on the measurement requirements above, and enable the signal at the measured position higher than gate thresh, so as to ensure correct measurement. In case AutoSearch or FloatingGain function does not work, disable auto functions and adjust manually.

2.

When Rectify is set at RF, RF, the default GAThresh is minus, i.e. measuring the negative signal of waveform (below the baseline).The measurement value is corresponding to the first peak of negative signal higher than GAThresh. The zero-crossing before the peak is stable, which is good for stable display of measurement value. When GAThresh is set as positive, positive , i.e. measuring the positive signal of waveform (above the baseline), the 19


measurement value is corresponding to the first peak of positive signal higher than GAThresh. The zero-crossing before the peak, influenced by baseline noise, is bad in stability, which is not good for stable display of measurement value. 3.

Rectify is recommended to be set as RF (at the same time, set GAThresh as minus) or Negative, so as to get the most stable measurement value display.

2.13

Veloci ty Measurement

General Work Flow

The general work flow of thickness measurement on the system is as shown in Fig. 3-1 in Normal mode. 24


3.2

Appl icatio n Keynote of Thickness Measurement

For most materials, such as carbon steel, etc., the general workflow above is practical and effective. On how to use the system, operation of calibration and auto search function in particular, please see Chapter 2 System Operation. When testing a thickness close to the critical measurement range, the auto-search function sometimes needs manual adjustment and decision by the operator, so as to ensure accurate measurement. While for coarse-grained, high-attenuation material (such as ductile iron), special composite material and multi-layer material, please adjust manually for measurement. It would be important that the operator has certain ultrasound theory and testing knowledge.

25

Functi onal Operation of Addi tion al Main Menu

E.4.1 PROBE The main menu PROBE shall be used with the menu V-PATH. In ProbeType, see the probe models available in Appendix C or Appendix D. The dual (TR) probes above have corresponding dialog dual probe models for option. Dialog dual probes enable auto probe identification, optimize the configuration between the main unit and the probe, and reduce measurement error. The dialog dual probe has an identification signal pin. When connecting a dialog probe, please connect the pin and the T/R plug right into the probe socket on the system carefully. When starting up the system, it can identify the probe type automatically, and use the built-in 58


parameters of the probe to set up. If probe connected, a

mark will be shown after the

probe type item. If disconnected, the mark will disappear. When a dialog probe is connected, ProbeType in the main menu Probe will include the optional probe model automatically (with the mark shown after the probe model) for selection. 【Note】:

ProbeCode: unique identification of probe type, cannot be changed by the users. V-PathSelect: Select the V-PATH curve for the current dual probe. Four options for selection: of f , Instrument , Probe and Custom. When using dual-element probe, the default setting is Instrument, which means adopting build-in V-path correction curve. When using dialog probe, the system automatically select Probe. For wear probes or probes from other manufactures, select Custom to use user-defined V-PATH curve. It is needed to apply existing or re-produced V-PATH curve to custom. If no need to modify, you can choose to turn off. When using single-element probe, V-PATHSelect is regularly off.

E.4.2 V-PATH A set of V-PATH calibration curve is set up by default in the system, which is for all the factory original dual probes. The users may make a set of V-PATH curve for a specific probe. When making a V-PATH curve, 10 measurement points can be set at most, and the 10 points should be in the actual measurement area where the user prefers to have smaller measurement error. For example, try to be below 10mm (steel longitudinal wave) or in the range of 20-40mm (steel longitudinal wave), rather than selecting any measurement point in the minimum to maximum measurement range. For high-precision application in different test range, the user may make a number of V-PATH curves. a)

How to make a V-PATH 1)

Set V-PathSelect to Off.

2)

Set V-PATH Enable to On.

3)

Select a test point on the test block, set TestBlockPoint at 1, which means to calibrate the first test point. 59


4)

Set TestBlockPointVal to a known value, e.g. 4.00mm.

5)

When the probe is in good coupling and the thickness reading is stable, set Calibrate to On, so as to record and calibrate the first test point.

6)

For calibrated test points recorded, a

mark will appear in TestBlockPointVal.

7)

Repeat steps 3)-5) to record more test points.

【Note】: 

b)

c)

d)

A valid V-PATH curve shall have at least 3 test points recorded.



Up to 10 test points can be recorded.



When making a V-PATH curve, V-PathSelect must be set to Off .

Save a finished V-PATH 1)

Select a blank file number in FileNum from V-PATH menu.

2)

Input a file name which is relevant to the curve and easy to be identified in FileName.

3)

Set Save to On and save the curve.

Recall a saved V-PATH 1)

Select a file number saved with the curve from FileNum.

2)

Set Recall to On and recall the curve.

Change a test point 1)

Select a test point to be deleted. saved curve which to be deleted

2)

Set DeletePoint to On.

【Note】: After being deleted, the test point will become uncalibrated. An uncalibrated test point

can be calibrated again. e)

Apply a curve as the current V-PATH curve

The curve with calibrated test points can be applied as the current V-PATH curve. Or the user may recall a saved V-PATH curve and apply it as the current V-PATH curve. Set Ap po yToCus to m to On, and change V-PathSelect to Custom. 【 Note 】 : In addition to Custom option for V-PathSelect, the other functions are: Off ,

Instrument and Probe. . Off :

To turn off V-PATH Enable function if not required for measurement.

Instrument : To use a set of calibrated curve in instrument de fault for measurement. Probe: To use a set of calibrated curve in the dialog probe for measurement. 60


E.4.3 TDG The TDG function is to compensate echo amplitude loss due to transmission sound path. Set TDGEnable in TDG menu On, and TDG function is enabled. The examples of figures before and after TDG function enabled are shown below:

Before TDG function enabled

After TDG function enabled 【Note】: When TDG function is enabled, a TDG line will appear on the screen.

InitGain: The initial dB value of TDG curve TDGSlope: the increment of dB value per us StartBlank: The valid start time of TDG curve MaxGain: The maximum gain that TDG reaches

61


E.4.4 TEMP In general, the higher the temperature of the solid material, the lower the velocity. Test data shows that, if the temperature of thermal material rises by 100°C, the velocity decreases by 1%. When the temperatures of the calibration test block and the tested work piece are different, the user may enable the temperature compensation function. Turn TempCompEnable item to On, enable temperature compensation function. 【Note】:

●DegreeUnits: Select the unit of temperature, ℉ (fahrenheit) or °C (centigrade) ●CalibrationTemp: The temperature of the workpiece when calibrating the system. Adjustable range: -10°C to 200°C or 14℉ to 392 ℉ .

●TempCoefficient : Temperature compensation coefficient. Adjustable range: -1.0 to 1.0. ●CurrentTemp: Temperature of the workpiece tested. Adjustable range: -10°C to 200°C or 14℉ to 392 ℉.

E.4.5 COAT When WorkMode is Thru-Coating, enable coating measurement function. Set up the velocity of the coating. While testing the thickness through coating, the system will test the thickness of coating. Option: 1) Select COAT menu, adjust CoatTHK to On and set up CoatVEL. 2) At this time, the measurement reading under coating is the measurement value between the zero-crossing before the first peak higher than GAThresh and the zero-crossing before the first peak higher than GBThresh. When CoatTHK is set On, the software will measure the zerocrossing of the first highest peak higher than GAThresh, and calculate the thickness of the coating. See the figure below for the corresponding peak position. See 2.11 for Information about zero-crossing. 【 Note 】 : By adjusting parameters like gain and gate position, make sure the wave form

amplitude and gate position meet the measurement requirements above (see the figure below). Otherwise, it will affect the test result. Please try to use manual adjustment in this case. 62
