CONVENTIONAL MODE DEMONSTRATION
The following topics should be demonstrated using a live instrument and demonstration probe/test piece: Pulser Functions Receiver Functions Gate Setup Auto-XX Straight Beam Calibration Cal Modes Reading Setup Reference Cursors Calibration File Storage Angle Beam Calibration Peak Memory Leg Grid Display Calibration Quick Recall Composite A-scan Enveloping Discussion

PRF Effects on A-scan Acquisition and Display EPOCH 1000 Series display updated at 60Hz PRF adjustment allows A-scan acquisition up to 6000Hz Maximum PRF means 100 A-scans acquired per screen update When more data is acquired than can be displayed, what does the EPOCH 1000 actually display?? Screen Updates (60xs per second) Individual A-scans acquired at PRF (each is one full waveform of data)

ClearWave™ Visualization Package The EPOCH 1000 Series provides multiple methods of displaying acquired A-scans to ensure the information displayed always represents the most important and relevant data for the inspection. The ClearWave™ Visualization Package is the group of functions that allow adjustment between these display methods. The methods included in the ClearWave™ Visualization package are: Composite A-scan Max Amplitude Min Thickness Averaged A-scan SureView™ Visualization Mode Persistance Mode Baseline Break

ClearWave™ Visualization Package 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. Even at high PRF, the operator will not miss a single indication! Can create enveloping effect with fast scanning Screen Updates Individual A-scans acquired at PRF Information Displayed Composite A-scan Mode

ClearWave™ Visualization Package Max Amplitude – Analyzes acquired A-scans between display updates and displays only the A-scan with the highest gated amplitude reading. Cleans up signal noise in applications where highest amplitude readings are the key factor for inspection. Does not display all acquired A-scans Screen Updates Individual A-scans acquired at PRF Maximum Amplitude A-scan Maximum Amplitude A-scan Information Displayed Max Amplitude Mode

ClearWave™ Visualization Package Min Thickness – Analyzes acquired A-scans between display updates and displays only the A-scan with the minimum thickness reading. Cleans up signal noise ratio for more precise thickness measurements when minimum thickness is the key factor for inspection. Does not display all acquired A-scans Screen Updates Individual A-scans acquired at PRF Minimum Thickness A-scan Minimum Thickness A-scan Information Displayed Min Thickness Mode

ClearWave™ Visualization Package Other important features: SureView™- Revolutionary technology for advanced crack detection and sizing. This standard feature mimics the A-scan representation of analog CRT displays, and allows the operator to visualize peak indications from reflectors even when the instrument range compresses these indication peaks beyond visual perception. Expected February 2009 Averaged A-scan – New functionality allows the operator to view an average of acquired A-scans. The user can select the precision of the averaging, choosing between 2X, 4X, 8X, 16X, 32X or 64X averaging to remove spurious noise signals from the A-Scan while maintaining relevant signals. Expected January 2009 Persistence Mode – New functionality that retains previously acquired A-scans on the instrument display for a predetermined amount of time. This feature holds A-scans on the screen while new A-scans are drawn for a user-selectable time interval to allow small windows of comparison to previous data. Expected February 2009 Baseline Break – Standard functionality on the EPOCH XT, this feature identified “zero-cross” points of each waveform using RF data and displays these “zero-cross” points as lines connecting individual A-scan lobes to the baseline on the display. This feature can help to visually separate far surface defect echoes from the back surface echo. Currently Available

OVERVIEW and PERFORMANCE
PHASED ARRAY MODE: OVERVIEW and PERFORMANCE

Phased Array Mode Overview
Phased Array Mode: Standard Group Menus

Phased Array Mode - Overview
Phased Array Imaging The EPOCH 1000 Series provides manual phased array imaging capabilities, either standard or optional, based on the following: EPOCH 1000 – Optional imaging requiring hardware/software upgrade EPOCH 1000iR – Optional imaging requiring only software upgrade EPOCH 1000i – Standard imaging capabilities Manual Imaging Manual imaging means that the images acquired cannot be encoded. The EPOCH 1000 Series phased array capabilities is designed for hand scanning applications to augment conventional techniques.

Angle Beam Inspections Phased array angle beam inspection typically provides two views: Sector Scan This image represents a composite of A-scans across a range of angles (typically 40°to 70°). This sector scan shows amplitude data of each angle in the angular coverage area at the same time. A-scan An individual A-scan is displayed from the sector scan. This A-scan represents a single angle, and is selected using a cursor. A-scan at 60°(selected)

Straight Beam Inspections Phased array straight beam inspection typically provides two views: Sector Scan This image represents a composite of A-scans across a range of angles (typically -30° to +30°). This sector scan shows amplitude data of each angle in the angular coverage area at the same time, including the 0° A-scan. A-scan An individual A-scan is displayed from the sector scan. This A-scan represents a single angle, and is selected using a cursor. This is usually the 0° A-scan in straight beam applications. A-scan at 0°(selected)

Phased Array Mode - Performance
Automated Gain (Sensitivity) Calibration The EPOCH 1000 Series features an automated sensitivity calibration procedure during phased array setup. This automated procedure, based on the OmniScan sensitivity calibration, allows the user to capture the peak amplitude response from a single reflector (usually side drilled hole) across all imaging angles (focal laws). The instrument then uses this amplitude capture to adjust gain at each angle (focal law) to position the amplitude from this reflector at 80% FSH for every A-scan. Gain Calibration Curve

Automated Wedge Delay Calibration The EPOCH 1000 Series features an automated wedge delay calibration procedure during phased array setup. This automated procedure, based on the OmniScan wedge delay calibration, allows the user to capture the TOF/distance measurement from a single reflector across all imaging angles (focal laws). The instrument then uses this TOF/distance capture to adjust the wedge delay at each angle (focal law) to provide correct TOF/distance measurements for every A-scan. Wedge Delay Calibration Curve

Image Smoothing Phased array imaging is based on composited amplitude responses of multiple A-scans. In many instances, A-scans can have multiple peaks when reflected from a single defect. This can affect the clarity of the S-scan. The EPOCH 1000 Series, therefore, allows the user to select stepped image smoothing, applied to both the A-scan and S-scan, to provide clearer images without significant impact on the precision of the measurement.

Frozen Image Analysis The EPOCH 1000i allows A-scan and image review and analysis while in FREEZE mode Raw A-scan data available for all angles/focal laws Full Gain, Gate and Cursor adjustment A-scan indication measurements live Image sizing cursors available for X2 – X1 and/or Y2 – Y1 indication sizing

Phased Array Specifications The EPOCH 1000i is a powerful conventional flaw detector with basic, manual phased array imaging capabilities. The specifications below are critical when compared to other phased array instruments to understand the benefits and limitations of the EPOCH 1000i.

Phased Array Imaging for the Conventional Inspector Better probability of detection through imaging More efficient inspections One Probe One Calibration Full Inspection Comply with Conventional Codes and Procedures!

Phased Array Software Features
Standard Sizing and Evaluation Techniques Coming soon in early 2009! As with conventional UT mode, the phased array mode incorporates the following standard sizing techniques: DAC/TVG DGS/AVG AWS These techniques are critical to allowing the EPOCH 1000i to be fully compliant with conventional codes, while still providing imaging benefits.

Phased Array Mode – Software Features
DAC/TVG The EPOCH 1000i has the capability to create a TVG setup during sensitivity (gain) calibration, as demonstrated earlier. This TVG setup is the same process as acquiring a DAC curve – it allows the user to reference the amplitude response of a known reflector at varying depths within the test piece. The EPOCH 1000i will allow the user to utilize this simple TVG setup mode during sensitivity (gain) calibration to create an individual DAC curve for every focal law. DAC curve will only be viewable on the selected A-scan DAC measurements will be active for the selected A-scan S-scan will always display in TVG view Available in early 2009

DGS/AVG The EPOCH 1000i also has the capability to create a DGS/AVG setup. However, since DGS/AVG is only valid for qualified probes at certain fixed angles, the DGS/AVG curves will not apply to all focal laws. The EPOCH 1000i will allow the user to utilize a similar setup menu as the DGS/AVG conventional setup, to calculate DGS/AVG curves for specified focal laws (typically 45°, 60° and 70°). Atlas-DGS Phased Array Probes must be used 4L16-DGS1 2L8-DGS1 DGS/AVG curve will only be viewable on the selected A-scan DGS/AVG measurements will be active for the selected A-scan Available in early 2009

AWS D1.1/D1.5 Weld Rating Software The EPOCH 1000i will have the capability to evaluate the ‘D’ weld indication value according to the AWS calculation of A-B-C=D for all three standard inspection angles (45°, 60° and 70°). This will allow the user to comply with the AWS code while gaining inspection speed and confidence. The EPOCH 1000i will allow the user to turn on the AWS feature and select a desired reference gain level (AWS stipulates over 50% FSH). The user will then use a tool similar to the sensitivity calibration tool to acquire a RefB value for all focal laws at once. AWS Phased Array Probe should be used 2,25L16-AWS1 Multi-law mode will be active, allowing the operator to only view A-scans that represent 45°, 60° and 70°. Available in early 2009

TROUBLESHOOTING

Troubleshooting Techniques
It is important, especially early in a product release, to identify ways to correct common issues or software glitches. This section describes three methods of correcting instrument failures and/or problems. Instrument Resets Hard Reset Compact Flash® Reset

Instrument Resets The EPOCH 1000 Series has several instrument resets built into the software Location: FILE group menu, RESETS parameter menu Corrects symptoms: Parameter cannot be adjusted Function/parameter seems to be missing Instrument is operational but “acting funny” Resets include: Master/Database – clears data logger, restores default parameters Parameters – maintains data logger, restores default parameters

Hard Reset The EPOCH 1000 Series features an external, hard reset function Create a file on a USB memory stick called ‘reset.txt’ File does not need to contain anything, just have this exact name/extension Turn off the instrument Plug USB memory stick into instrument Turn on the instrument Corrects Symptoms: Unit will not finish loading after initial start up Strange functions and crashes that instrument resets do not solve Reset clears data logger and restores factory default settings to instrument

Compact Flash® Clear The EPOCH 1000i stores limited phased array probe information on the Compact Flash® card. If this data gets corrupted, clearing the flash card may solve any issues. Resets any custom phased array probe setups Corrects Symptoms: Instrument displays a ‘PA_Benchmark.exe’ error upon boot up Instrument will not complete boot up after a software upgrade Rare requirement User must have a Compact Flash® reader to perform the clear Simply delete all files on flash card, return to instrument and turn on
