The
EPOCH 600
is
also
capable
of
outputting
alarm
signals
through
the
9

pin
D
‐
sub
connector
on
the
back
panel
of
the
instrument.
2.4
Calibration
The
EPOCH 600
can
be
easily
calibrated
for
both
zero
offset
and
velocity
in
order
to
provide
accurate
thickness
(soundpath)
measurements
from
indications.
The
EPOCH 600
utilizes
an
auto
‐
calibration
system
for
a
simple,
two
‐
step
approach.
The
section
below
outlines
the
most
standard
and
basic
calibration
example.
More
detailed
information
on
calibration
can
be
found
in
the
EPOCH 600
User’s
Manual
(P/N:
DMTA
‐

2.4.1
Measurement calibration
Calibration
for
accurate
digital
measurements
is
typically
accomplished
using
two
known
thicknesses
of
a
representative
material.
In
this
section,
the
terms
THIN
and
THICK
will
be
used
to
refer
to
either
two
thicknesses
of
a
block
or
plate
(straight
beam
calibrations)
or
two
lengths
of
an
angled
soundpath
(angle
beam
calibration).
To begin calibration
1.
Couple
the
transducer
to
the
thin
step
of
the
material.
2.
Position
gate 1
around
the
resulting
indication
on
screen.
3.
Bring
the
indication
to
80 %
full
screen
height
using
the
(AUTO
XX%)
function.
4.
Select
the
