4.3.1 Main Toolbar: File

Click File to load collected data measured in the window.

Figure: File List

4.3.2 Main Toolbar: Multichannel View

Collected data acquired with MultiChannel settings can be verified in the Channel-1 list consisting of multiple channels.

Figure: Multichannel View List

4.3.3 Main Toolbar: Soft Gain

Amplitude values of collected data acquired with Soft Gain can be reset.

Figure: Soft Gain List

4.3.4 Main Toolbar: Scan View

The Scan View area provides the function to view collected data in various forms.

Scan View is a 2D graphical representation of ultrasonic data with rulers or scales corresponding to horizontal and vertical axes. For example, A Scan and C Scan are two types of Scans.

Figure: Scan View List

Scan View layout can configure one or more windows in various forms. For example, A-B-C layout means A Scan View, B Scan View, and C Scan View windows. In window arrangements with two or more viewing windows, cursor and zoom settings are applied to a specific single Scan View window.

Scan View represents ultrasonic signals in various ways, including signal overlays. Each Scan View has two axes. Also, each Scan View is linked with one Channel Group and displays only data corresponding to its own Channel Group. Therefore, in a layout with multiple Channel Groups, selecting and activating a desired Scan View will change the current Channel Group control at the top left to that Scan View’s Channel Group.

Table: Scan View Screens

• A-scan View The foundation for all other viewing windows. It displays received ultrasonic amplitude or waveforms by generating ultrasonic beams. Peaks in the signal correspond to reflected signals from reflectors or discontinuities within the test object. Generally, peaks at the start and end of the ultrasonic axis correspond to reflected signals from the specimen surface and backwall.

• B-scan View A Scan View representing a 2-D side view of the test object showing ultrasonic data using one axis as Scan axis length and the other as ultrasonic path.

• C-scan View A Scan View representing a 2-D top view of the test object showing ultrasonic data within the Gate Bar using one axis as Scan axis length and the other as Index axis length. One applicable variable (e.g., maximum amplitude) is projected onto the Index-Scan plane for each pixel. C Scan is also called Top View.

• D-scan View A 2D surface display of the Index part and US data with scan length on one axis and US path on the other.

• S-scan View A Scan View showing 2D ultrasonic data representing all A Scans generated by focal laws in an angular range or steering range to create a cross-section of the test object. A single A Scan is represented by a line where amplitude is converted to color, and the actual position is corrected via Wedge Delay so each data position accurately matches the ultrasonic axis.

• Rulers Each ruler/scale has a dedicated color to help identify axes of different colors. The following table provides a list of available rulers/scales and related colors and functions.

  Primary color is a property of each axis. Axes appear in various shades of the primary color. The brightest shade corresponds to raw data representation. Progressively darker shades relate to increased data correction complexity relative to the axis. Darker shades are also used for reference axes.

Table: Rulers Description

Note: Colors in this manual may vary slightly.

4.3.5 Main Toolbar: Reference / Measurement Bar

Reference / Measurement bars are activated in the Scan window when clicked.

Figure: Reference / Measurement Toolbar

The role of each Bar is for measuring defect size.

Measure defect size while adjusting active bars left/right or up/down.

4.3.6 Main Toolbar: Data Bar

The Data Bar is activated in the Scan window when clicked.

Figure: Data Toolbar

The Data Bar is a reference line specifying a particular scan position in collected PAUT data. Completed scan data contains image information for all positions traveled by the probe. Moving the Data Bar left and right simultaneously updates data collected at that position across A-scan, B-scan, C-scan, and S-scan views. Simply put, the Data Bar is a reference point for “viewing data at this position.”

4.3.7 Main Toolbar: Gate

Consists of a total of 3 gates: A / B / I Gate.

Figure: Gate Toolbar

Gates are activated by clicking and displayed on the A-scan. Also, active gates are displayed on the S-scan so you can see on screen where measurements are being taken.

Gates can be used to set the Index area for C-scan. Also, height and position of signals captured in the gate can be verified.

4.3.8 Main Toolbar: Zoom mode & Zoom reset

Zoom mode is a function used to magnify defects or specific positions in collected data.

Figure: Zoom mode Toolbar

Activated by clicking Zoom mode; dragging the mouse on screen displays an area and magnifies that position.

Color map is a color range setting window used for measuring corrosion.

Activated by clicking the list.

Figure: Color map screen

Color Map is divided into two types:

First is a generally used Color Map based on A^.

Figure: Color Map A^ applied screen

Second is the Color Map used when performing Corrosion mapping.

Figure: Color Map A Position applied screen

Corrosion Color Map is automatically applied when changing to A/, B/, A/-B/, or Position.

Also, to further distinguish color differences, Min / Max can be used to reset range differences. Linear and Reverse functions allow smoothing or inverting colors.

Figure: Color Map Toolbar

Color map allows finer adjustment of color differences so even minute thickness variations can be easily distinguished visually.

Gate / Range Control is a list for readjusting position settings for Gates and setting values for View Range.

• Gate: Select desired Gate via Kind to change position by setting Start / Range / Threshold.

• View Range: A frequently used function when wanting to see only specific areas while excluding others. After setting approximate positions in the Scan window, View Range Control can be used to readjust precise position values.

4.4.4 Calibration

Calibration is a function for verifying parts related to calibration.

Figure: Calibration List

Calibration includes Wedge delay / Velocity and even TOFD. Adjusting these values reflects them in each Ruler without changing the image.
