Standard Software Features
Dynamic DAC/TVG: Calculates signal amplitude as a percentage or decibel level compared to a DAC curve or a reference echo amplitude fixed at a time-varied gain. DAC versions include ASME, ASME 3, JIS, and Custom. Also includes several key features: dynamically adjustable DAC curves, switchable DAC and TVG views, and custom DAC warning curves.
DGS/AVG: This flaw sizing technique allows echo signals to be evaluated with a DGS/AVG diagram associated to a particular type of probe and material. The DGS/AVG diagram illustrates the relationships between echo height, flaw size, and distance from the transducer.
Curved surface correction: Corrects sound path information when using an angle beam transducer to circumferentially inspect a curved surface for either tubular or bar inspections.
Optional Software Features
AWS D1.1 and D1.5: Provides a dynamic reflector indication rating for various AWS weld inspection applications. This allows more efficient inspections by eliminating manual calculations.
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.
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 bacwall while still monitoring the backwall echo for drop-out of 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 prove-up process of OCTG pipe. The measurement process is simple and repeatable since all ADDT variables are captured from a Peak Memory envelope.
Waveform Averaging: This feature allows the live A-scan view to represent an average of successively acquired A-scans. Waveform averaging improves signal-to-noise ratio when static flaws are detected. Averaging in 2X, 4X, 8X, 16X, and 32X.
Data Logging and PC Interfacing
The EPOCH 600 allows several methods of storing, archiving and reporting inspection and calibration data. The instrument features up to 50,000 points of onboard memory, augmented by an additional 2 GB of removable memory. It is also fully compatible with Olympus NDT's PC interface program, GageView™ Pro. With quick file setup functions and flexible data management, logging and reporting inspection data is simple and efficient.
The EPOCH 600 is fully compatible with our PC interface program, GageView™ Pro. You can download inspection data, review measurements on a PC, export measurements and calibration data to common spreadsheet programs, back up calibration and inspection data from the instrument, and perform basic operations such as instrument firmware upgrades and screen captures.
The EPOCH 600 features on onboard data logger for calibration and inspection file storage. The instrument comes standard with two primary files types: calibration (CAL) and incremental (INC) files. CAL files allows you to save a virtually unlimited number of parameter setups for fast and easy recall to live settings. INC files store multiple pieces of inspection data under a single file name for downloading and reporting by inspection.
The onboard data logger can be enhanced to feature full corrosion-style data logger file types through the Expanded Datalogger software option. This option includes the following data file types: sequential, sequential with custom point, 2-D grid, 2-D grid with custom point, 3-D grid, boiler, 2-D EPRI.
The EPOCH 600 utilizes 2 GB MicroSD memory cards for both onboard and removable memory. Through removable memory, you are able to store screen images in bitmap format for easy reporting, as well as exporting current or saved measurement and calibration data in .csv format. A second 2 GB MicroSD card is mounted to the PC board inside the instrument, and is responsible for all onboard data storage. In the event the instrument is damaged beyond repair, this MicroSD card can be removed at an authorized service center, allowing the operator to recover critical data from the damaged instrument.

Corrosion Module Overview
The EPOCH 600 includes a specialized feature called the Corrosion Module, designed for inspectors that require both flaw detection and corrosion measurement solutions as standard application offerings. This optional software provides simplified instrument operation for corrosion applications, requiring less set up time and more efficient data collection. The Corrosion Module leverages many of the industry-leading corrosion inspection features revolutionized by dedicated corrosion thickness gages such as the Olympus 38DL PLUS while maintaining a close connection to standard flaw detector operation. This combination significantly lessens the requirement for operator training and enhances the versatility of the already popular EPOCH 600 instrument.
The Corrosion Module is intended to provide a rapid and simple solution for flaw detector users to perform basic corrosion inspections. The feature is compatible with several industry leading dual transducers from Olympus, including the D790. Once the appropriate transducer is selected, the Corrosion Module intelligently adjusts the pulser/receiver settings for optimal ultrasonic inspection quality. Measurement thresholds and gain adjustments are handled automatically, allowing immediate thickness measurements with minimal operator input. Using this feature, the operator is no longer required to constantly adjust the start, width and level of gates to maintain measurement consistency and avoid interfering geometric echoes. Echo-to-echo measurements are also possible (and simple) with the EPOCH 600 Corrosion Module.
The Corrosion Module includes many features common to dedicated corrosion thickness gages. These features allow efficient and accurate inspections, and include:
- Automatic pulser/receiver setup based on probe selection
- Automatic zeroing of transducer for wear compensation (Do-Zero)
- V-Path correction
- Thickness gage measurement algorithm
- Single echo or Echo-to-Echo measurements
- Blanking of noise and shear wave echoes for proper measurement
The Corrosion Module also features corrosion-style data logger file types, including 2D grid files and sequential files. A color-coded Grid View is also available for live visual analysis of material thickness trends by inspection area. The color coding of this Grid View can be displayed with up to three user-defined thickness ranges.
The Corrosion Module also includes a timed B-scan view. This B-scan is collected based on a single echo or from Echo-to-Echo measurements. The B-scan can be colored in up to three user-defined thickness ranges. This B-scan is used for fast data collection and consolidated reporting of areas of interest.
The technical specifications of the Corrosion Module include:
|Corrosion Module Specifications|
|Supported Transducers||D790 (5MHz), D798 (7.5MHz)|
|Maximum Thickness Range||254 mm (10 inches) @ 5900 m/s (0.2320 inches/µsec)|
