DAC versions include ASME, ASME 3, JIS, and Custom. Contains several key features including: dynamically adjustable DAC curves, switchable DAC and TVG views, (20% to 80%) DAC/TVG, a flexible TVG table, and custom DAC warning curves. B-Scan Single value (thickness) based B-scan that allows fully encoded or manual scans for corrosion monitoring. Simultaneous viewing of an A-scan and B-scan is available. Operates in all test modes including: TVG, Echo-to-Echo, and Floating Gate. Includes Floating Gate option. CSC (Curved Surface Correction) Corrects sound path information when using an angle beam transducer to circumferentially inspect a curved surface. DGS/AVG Flaw sizing technique that permits echo signals to be evaluated using a DGS/AVG diagram associated with a particular type of probe and material. The DGS/AVG diagram shows the relationship among echo height, flaw size, and distance from the transducer. Floating Gate Gate option, which allows the operator to “float” Gate 1 and/or Gate 2 at a selected height compared to a gated echo (–1 dB to –14 dB). This feature is intended to allow more consistent, precise readings, especially in Edge Detection mode. This option is included in the B-scan option. AWS D1.1 & D1.5 Provides a dynamic reflector “indication rating” for various AWS weld inspection applications. This allows for more efficient inspection by eliminating manual calculations. EPOCH XT DGS/AVG The AVG/DGS Binder, contains a DGS diagram and specification sheets for each angle beam, dual element, and protective face transducers from the Olympus NDT Atlas Transducers series. These diagrams are printed on splash and tear proof paper and housed in a six-ring binder. 4 www.olympus-ims.com www.olympus-ims.com Template Storage Interface Gate Template Storage Allows on-screen comparison of a live waveform with a saved reference waveform. Saved templates can be dynamically toggled on and off with a single key press for fast waveform comparison. Gain adjustment feature allows each saved template a unique base gain for inspections requiring varying sensitivity levels. Excellent for spotweld analysis and other applications. Interface Gate Advanced Filters The Advanced Filters option takes advantage of the EPOCH XT’s unique digital receiver design and allows unprecedented filtering flexibility. This option allows the EPOCH XT operator to choose from 37 different filter settings. Specific performance improvements from this option include: • Performance improvement with low- frequency probes com- monly used for inspection of composites and plastics. • Improved initial pulse recovery with new DC coupled setups. • Optimized broadband response from mid- to high-frequency transducers. • Use of very low frequency transducers (50 kHz to 100 kHz range) for specialized applications. This optional third measurement gate enables real-time tracking of a variable interface echo in order to maintain consistent digital measurements. Backwall Echo Attenuator (BEA) Attenuates the backwall echo of an inspected part using the screen region defined by Gate 2. BEA is used to avoid screen saturation of the backwall echo to allow detailed flaw echo examination in the part region before the backwall while still monitoring the backwall echo for drop-out or signal reduction. API 5UE Allows defect sizing according to API Recommended Practice 5UE. Uses the Amplitude Distance Differential Technique (ADDT) to measure the size of potential defects during the proveup process of OCTG pipe. The measurement process is simple and repeatable since all ADDT variables are captured from a Peak Memory envelope. API 5UE 5 Extensive Documentation and Data Management Capabilities GageView Pro® The optional GageView Pro interface program helps manage and format stored inspection data. Data can be printed or easily copied and pasted into word processing files and spreadsheets for further reporting needs. The GageView Pro interface program also allows the creation of a customized database of identifier (ID) strings that can be uploaded to the EPOCH XT. New features include remote display of live EPOCH XT screens on a PC, Live-Screen Capture mode, database backup/restore, and multiview windows.
