Using
the
Type
K
Thermometer
(TG56
only)
A
Type
K
thermocouple
thermometer
jack
is
provided
at
the
top
of
the
TG56.
The
thermocouple
plug
has
a
wide
and
a
thin
connecting
blade,
please
insert
the
thermocouple
carefully,
in
the
correct
orientation;
do
not
force
it
into
the
jack.
When
a
thermocouple
is
connected,
the
temperature
of
the
surface
in
which
the
thermocouple
is
touching
is
displayed
(next
to
the
icon)
along
with
the
IR
temperature
reading.
The
display
mode
area
of
the
screen
(middle
of
top
row
of
icons)
shows
the
thermocouple
icon
when
a
thermocouple
is
connected.
The
difference
between
the
IR
reading
and
the
thermocouple
reading
is
displayed
next
to
the
delta
icon
.
When
a
thermocouple
is
connected
to
the
meter
other
operational
modes
are
not
available.
5.6.1
Using
the
Type
K
Thermometer
to
set
Emissivity
1.
Measure
the
surface
of
the
object
under
test
with
the
IR
Thermometer.
2.
Measure
the
same
surface
with
the
Type
K
thermocouple
thermometer.
3.
Note
the
difference
(delta)
between
the
two
readings.
4.
Now
adjust
the
Emissivity
in
the
Programming
menu
(Section
6)
so
that
the
IR
thermometer
reading
matches
the
Type
K
thermometer
reading.
5.
When
this
is
accomplished
the
emissivity
setting
is
correct
for
the
surface
in
question.
Thermocouple
notes
:
The
supplied
general
purpose
thermocouple
is
not
rated
for
the
entire
measurement
range
of
the
meter.
The
thermocouple
can
be
damaged
if
temperature
outside
its
specified
range
is
measured.
In
all
cases,
please
use
a
thermocouple
that
is
rated
for
the
intended
application
only.
Refer
to
the
specifications
section
of
this
User
Manual
for
meter
temperature
and
thermocouple
temperature
ranges.
The
accuracy
characteristics
of
the
thermocouple
probe
should
be
added
to
the
accuracy
specification
of
the
meter
when
interpreting
thermocouple
readings.
The
IR
thermometer
averages
a
larger
area
than
the
thermocouple
probe,
thus
the
emissivity
adjustment
procedure
in
Section
5.6.1
is
an
approximation.
