Simple and Durable Operation

The EPOCH 600 design is focused on providing a very high level
of flaw detection with the simplicity of a basic instrument. The
EPOCH 600 is designed to be ergonomic, intuitive, and practical
for both experienced and novice ultrasonic inspectors.

Intuitive User Interface

The EPOCH 600 user interface is based on the industry approved
EPOCH 1000 Series imaging flaw detector. The EPOCH 600 com­bines a simple menu structure for instrument settings, calibration
and software feature adjustment, with the EPOCH brand’s hall­mark direct-access key approach for critical inspection functions
such as gain and gate adjustment, screen freeze, and file save.
Supported in multiple languages, the EPOCH 600 user interface is
intuitive for any level of operator.

Portable Design for All Inspection Environments

The EPOCH 600 is designed for use in nearly any inspection
environment, from bench top testing in a laboratory to extreme
outdoor and hazardous conditions. Designed for IP rating in
either knob (IP66) or navigation pad (IP67) configurations, and
tested to very high environmental and reliability standards,
the EPOCH 600 allows users in any inspection environment
to feel confident in both the performance and durability of
the instrument. The instrument is tested for vibration, shock,
explosive atmosphere, and wide temperature ranges. And with
a battery life to exceed 12 hours, the EPOCH 600 is the perfect
solution for remote inspection locations.

Vibrant Full VGA Display

The EPOCH 600 features a full VGA (640 x 480 pixels) resolu­tion display. The horizontal design of the EPOCH 600 optimizes
the A-scan size and readability on this high quality display. Built
with transflective technology, this VGA display provides excel­lent clarity in indoor, low lighting conditions using its powerful
backlight, as well as in direct sunlight by using the ambient light
as a pseudo-backlight.

Optimized Access to Powerful Features

The EPOCH 600 provides excellent quality ultrasonic perfor­mance. Based on the same digital architecture as the EPOCH XT,
LTC and EPOCH 1000 Series, the EPOCH 600 provides flexible,
powerful pulsing and receiving features to accommodate the
needs of most flaw detection inspections.

Pulser/Receiver

The EPOCH 600 comes standards with powerful flaw detection
capabilities, such as:

• PerfectSquare

• Digital high dynamic range receiver

• Eight 100% digital filter sets

• Auto or manually adjustable PRF from 10 Hz to 2000 Hz

• Pulser voltage from 100 V to 400 V

• Amplitude resolution to ± 0.25%

• Five customizable digital measurements

EPOCH 600 Dynamic DAC/TVG Feature

™

tunable square wave pulser

EPOCH 600 Echo to Echo with Gate Tracking

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.

Options for Comfortable Navigation

In order to accommodate different user needs and preferences, the EPOCH 600 is available in
two hardware configurations: one with an adjustment knob and the other with a navigation area
on the keypad. The adjustment knob and the arrow keys on the navigation pad are responsible for
parameter adjustment and value slewing.

Knob

The adjustment knob on the EPOCH
600 is used along with the CHECK
and ESC keys to adjust parameter
values in either coarse or fine incre­ments. You have the ability to lock
the knob to prevent accidental pa­rameter value changes during an in­spection. This configuration provides
smooth value slewing for customers
who prefer adjusting parameters us­ing a knob. The knob configuration
is designed to meet the requirements
of IP66.

4

Navigation Pad

The EPOCH 600 navigation pad is a
hallmark feature of the EPOCH flaw
detectors. The up and down arrows
on the navigation pad are used for
coarse parameter adjustment, and
the left and right arrows for fine
adjustment. The navigation pad also
contains additional functions and
frequently used parameters such as
gain, save, and the CHECK and ESC
keys. The navigation pad configura­tion is designed to meet the require­ments of IP67.

Versatility Through Optional Performance

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.

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.

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.

Interface Gate

This optional third measurement gate enables real-time tracking
of a variable interface echo in order to maintain consistent digital
measurements.

Data Logging and PC Interfacing

Data Management

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
quick file setup functions and flexible data management, logging
and reporting inspection data is simple and efficient.

GageView™ Pro

The EPOCH 600 is fully compatible with our PC interface pro­gram, GageView
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.

™

Pro. You can download inspection data, review

Data Logger

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.

MicroSD

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.
