Atec Epoch-4 User Manual
ULTRASONIC FLAW DETECTOR
The Panametrics-NDT™ EPOCH 4 is
an advanced digital ultrasonic flaw
detector that combines powerful, fully
featured measurement capabilities, a
comprehensive internal datalogger, and
a wide range of software options to solve
many demanding inspection problems.
Signal processing features include a 25
MHz bandwidth to permit testing of
thinner materials, a selectable square
wave pulser to optimize penetration
on thick or attenuating materials, and
narrowband filters to improve signal-tonoise ratio in high gain applications. The
EPOCH 4 incorporates rugged packaging
and a conveniently organized directaccess keypad, and offers the choice
of high-resolution Liquid Crystal or
Electroluminescent displays.
A large capacity datalogger allows field
storage of test data that can then be
transferred to the PC via its versatile
GageView PRO Interface Program.
EASY AND FAST OPERATION
The EPOCH 4 with its robust packaging
design, large display, and functional
color-coded keypad provides easy and
fast operation in difficult inspection
environments.
Important keys such as Gain, Freeze,
Save Thickness, Save Waveform, Enter,
and Slewing Keys are grouped together
for easy thumb control and one-handed
operation of all critical parameter
settings.
The five Function keys allow quick access
to preset parameter values that can be
customized by the operator.

TUNABLE SQUARE WAVE
PULSER – STANDARD FEATURE
The EPOCH 4 set a new industry standard
in 2001 when it was introduced with both a
Tunable Square Wave Pulser and a Negative
Spike Pulser. These high voltage pulsers offer the
operator extensive application versatility and
ease of use. The Tunable Square Wave Pulser
along with Narrowband filtering produce classleading material penetration and signal-to-noise
ratios in difficult materials such as cast metals,
large forgings, composites, and plastics.
Both pulsers are standard equipment on the
EPOCH 4PLUS, EPOCH 4, and EPOCH 4B,
and optional on the EPOCH LT.

INTERNATIONAL VERSATILITY
The EPOCH 4’s keypad is available in
English or International Symbols. Display
languages are keypad selectable in
French, German, Spanish, Italian,
Russian, Japanese, English, and a
custom user defined language.
AN AWESOME DISPLAY OF
CHOICES
LCD or ELD: The EPOCH 4’s Liquid
Crystal Display provides cutting edge
brightness and optimum viewing of the
waveform in conditions from bright,
direct sunlight to complete darkness.
The Electroluminescent Display offers a
fast update rate, four brightness levels,
and a very high degree of sharpness.
SOPHISTICATED ALPHANUMERIC
INTERNAL DATALOGGER
The EPOCH 4’s sophisticated datalogger
is designed for ease of use while providing a wide range of features for virtually
all flaw detection and thickness gaging
applications. All saved data can be organized in alphanumeric file names and
identifier (ID) codes that can be scrolled
and reviewed on-screen. A Memo feature
permits entry of additional inspection
data and the Edit feature can be used to
add, delete, or clear file names and ID
numbers.
Save and recall inspection data sets in
any combination of 500 waveforms (or
instrument setups) or 10,000 thickness
readings. The expandable memory option
saves any combination of up to 2,000
waveforms or 40,000 thickness readings.

EXTENSIVE DOCUMENTATION
AND TRANSFER CAPABILITIES
The optional Windows-based GageViewTM
Pro Interface program adds practical
collection, editing, and review capabilities to
the EPOCH 4. GageView Pro is a powerful
tool that collects, manages, and formats
stored inspection data.
GageView Pro database tracking allows
setup of inspection plans with pre-loaded
calibrations, IDs, and memos. Data can be
printed or easily copied and pasted into word
processing and spreadsheet documents for
further reporting needs. GageView Pro is
compatible with the EPOCH 4, EPOCH LT,
EPOCH 4B and EPOCH 4PLUS flaw
detectors.
