3. Editable Parameters

4. Editable Parameters • The Editable Parameters function similar to the EPOCH XT is now a standard software feature on the EPOCH 1000 Series. • This feature allows the user to customize the preset values that are displayed during coarse adjustment for these specific parameters. • If desired, the user can then export the editable parameters setup in XML format to a USB memory stick and import to another EPOCH 1000 Series instrument. • To access the Editable Parameters menu, select Inst Setup > Editable Parameters.

5. Editable Parameters- Conventional UT • Each instrument mode (UT and PA) has its own Editable Parameters menu with separate sets of parameters. • UT Mode Parameters: • Velocity • Gain Step • Freq • Angle • Thick • X Value • Auto XX

6. Editable Parameters- Phased Array • Each instrument mode (UT and PA) has its own Editable Parameters menu with separate sets of parameters. • PA Mode Parameters: • Velocity • Gain Step • Freq • Thick • Auto XX

7. Editable Parameters- Changing Values • The instrument comes with certain preset values for each of the parameters, but the user can change any of these values as necessary to meet their needs. • To change a preset value: • Select the parameter you want to edit, and press the right arrow to view the Selection measurements. • Choose the value you want to change, and press the CHECK key. • Adjust to the desired value and press CHECK to confirm.

8. Editable Parameters- Adding Values • Users can add a virtually unlimited number of preset values to most of the editable parameters. • Exceptions are Gain Step (2 preset values) and AutoXX (1 preset value). • To add a preset value: • Select the parameter you want to edit, and press the right arrow to view the Selection measurements. • Press [P1] to Add a preset value. • Adjust to the desired value and press CHECK to confirm. • The new value will be added to the bottom of the list. To rearrange the order of the preset values, use the Move Up [P3], Move Down [P4], or Sort [P5] functions. • To Delete a preset value, select the desired value and press [P2].

9. Editable Parameters- Adding Values (cont.) • The EPOCH 1000 can only accommodate certain pulse frequency values. If a non valid frequency value is entered, the instrument will display an error and automatically rounds down to the closest valid frequency.

10. Editable Parameters- Adding Values (cont.) • In the Beam setup menu in PA mode (PA Probe > Beam), the preset values for Thick and Velocity will also be displayed above the parameter P-keys.

11. Editable Parameters- Other Information • If desired, the user can export the editable parameters setup in XML format to a USB memory stick and import to another EPOCH 1000 Series instrument using the [P1]Export and [P2]Import functions. • To Reset the Editable Parameters back to the system default values, press [P3]. NOTE: For parameters that have different values in Metric and English units (e.g. Velocity), the user can store different values in each measurement system. Only the values for the current units setting will be displayed in the Editable Parameters menu.

12. GUI Speed Updates

13. Parameter Coarse and Fine Adjustment • When changing parameter values using Coarse adjustment, all digits after the digit being adjusted are set to zero for the following parameters: • Range • Delay • Zero (UT Only) • Fine adjustment will allow the user to modify the remaining digits. Fine Adjustment Coarse Adjustment

14. Parameter Coarse and Fine Adjustment (cont.) • Adjusting the parameters below using Coarse adjustment will toggle through the preset values from the Editable Parameters screen: • Velocity • Frequency • Angle (UT Only) • Thick • X-Value (UT Only) • Fine adjustment will scroll through all non-preset values. Coarse Adjustment Fine Adjustment

15. Phased Array Image Updating • The Auto-XX% function in PA mode has been drastically improved and is now much faster than in previous versions! • The update speed of the image/A-Scan in PA mode for adjustments like Range, Delay, Gain, and Gates has also been increased. • These two improvements provide a more real-time response of the instrument during parameter adjustment.

16. Standby Mode

17. Standby Power Mode • The user now has the option to put their EPOCH 1000 unit in Standby Mode rather than turn it off completely. • Standby mode uses half as much battery life in a given time period as leaving the unit on! • When the unit is put into Standby mode, the unit saves the current on-screen parameters to display them again at start-up, or in case power is accidentally lost while in Standby mode. When the unit is in Standby mode, the 3rd LED on the front of the unit will blink.

18. Standby Power Mode (cont.) • Controls for Standby mode are in the Inst Setup > General menu. • Power Key Function • Standby gives the user the option of putting the unit into Standby when they press the Power key • On/Off will simply turn the unit off when the power key is pressed • Max Standby Time • Sets the amount of time the unit will remain in standby mode before shutting down.

19. New Icons and Measurements

20. A-Scan Measurement Mode Icons- UT Only • A-Scan measurement modes are part of the ClearWave™ package in Conventional UT mode on the EPOCH 1000. • The user can select from one of three A-Scan measurement modes: • Composite A-scan – Standard display mode from the EPOCH XT, this feature displays all A-scans acquired in between screen update rates (multiple A-scans when PRF > 60Hz) and overlays them together on the screen. • Max Amplitude – Analyzes acquired A-scans between display updates and displays only the A-scan with the highest gated amplitude reading. • Min Thickness – Analyzes acquired A-scans between display updates and displays only the A-scan with the minimum thickness reading.

21. A-Scan Measurement Mode Icons- UT Only (cont.) • An icon is now displayed on the home screen indicating which A-Scan measurement mode is active. • The A-Scan measurement mode is accessed using ClearWave > Ascan Mode. Composite Max Amplitude Min Thickness

22. New Digital Reading Measurements • The parameters below have now been added to the EPOCH 1000 Series as digital measurement readings: • A, B, and C AWS Measurements • Two new readings measuring amplitude height differences between gates 1 and 2 in dB units have also been added: • dBG1-2 and dBG2-1 • Example: • Gate1 echo = 80% • Gate2 echo = 40% • dBG1-2 = 6dB • These readings can be selected under Meas Setup > Reading Setup

23. Color Scheme Changes

24. Customize A-Scan Color • The user now has the ability to choose the color of the live A-Scan for both UT and PA modes. • To change the A-Scan color, select Display Setup > Color Setup. Color choices will display above the P-keys. UT Color Setup Menu PA Color Setup Menu

25. Customize Warning Curve Color • The user can now set the DAC/TVG and DGS warning (secondary) curves to be a different color from the main inspection curve in both UT and PA Modes. • To change the Secondary Curve Color, select Display Setup > Color Setup. Color choices will display above the P-keys. ASME-3 DAC Curve with Red Warning Curves

26. Additional Phased Array Color Palettes • There are now additional color palettes available for PA sector, linear, and C-scans to provide different color scales for use with varied applications. • To change the color palette • Select PA Display > Scan Palette (Depth Palette for depth C-Scans) • Or select Display Setup > Color Setup.

29. PA Color Palette Adjustment- Amplitude • Each of the color palettes has a preset color scale that is applied over the full range of signal amplitudes from 0-110% FSH. • The user can adjust the maximum and minimum amplitude color values using the parameters below under Amplitude Palette Control settings: • Palette Start: sets the upper color threshold for signals above the set amplitude • Palette End: sets the lower color threshold for signals below the set amplitude • The new adjusted color scale will be displayed to the left of the settings in the Color Setup menu.

30. PA Color Palette Adjustment- Amplitude (cont.) • Default settings for Amplitude Scan Palette: • 256 level color gradient distributed evenly from 0% to 110% FSH • Palette Start adjusted from 0% to 20%: • Lowest 0% gradient color (white) extended to 20% • Color gradient continues at default level for 20%

31. PA Color Palette Adjustment- Amplitude (cont.) Default settings for Amplitude Scan Palette • Adjusted S-Scan using modified Amplitude Scan Palette: • Palette Start adjusted from 0% to 20% • All echoes below 20%FSH are displayed in white on the S-Scan.

32. PA Color Palette Adjustment- Depth • For Depth C-Scans, the color palette scale is set in one of two ways depending on how the Source parameter is set: • Gate: The color scale is set with the gate start and end points as the minimum and maximum values of the scale with the colors distributed evenly over the gate width. • Custom: The user manually sets the start and end points of the color scale. The colors are then distributed evenly between the start and end points. • NOTE: The Reference Cursors on the A-Scan can be helpful in determining start and end points. • The user can also select how many color levels to use to span across the start and end points using Depth Palette Levels

33. PA Color Palette Adjustment- Depth (cont.) • Default Palette Source set to Gate: • Four palette levels distributed over gate width 1”

34. PA Color Palette Adjustment- Depth (cont.) • Palette Source changed to Custom: • Gate 1 points adjusted to capture only the area of part containing flaws • Four palette levels now distributed over flaw area only • Colors can also be adjusted to include entire part thickness without interference from gated initial pulse or backwall echo 1”

35. PA Color Palette Adjustment- Depth (cont.) Adjusted C-Scan using Custom Depth Scan Palette. Color gradient restructured around hole depth rather than gate position Initial C-Scan using Corrosion Scan Palette and Gate Source

36. TVG Gain Curve

37. TVG Gain Curve • When setting up DAC/TVG, the user can turn on a visual gain curve to show how the gain changes on a standard TVG. • This feature is available for both UT and PA DAC/TVG setups. • To turn on the Gain Curve, select Sizing Option > DAC/TVG. • NOTE: The color of the Gain Curve is the same color as the Secondary Curve Color that is set in the Display Setup > Color Setup
