CONNECTING A THERMOCOUPLE
Use the correct thermocouple type for your instru-
ment. Using an incorrect thermocouple type will
result in erroneous readings. Thermocouples are
color coded by type using the North American ANSI
Color Code as follows:
TYPE COLOR
J Black
K Yellow
T Blue
Thermocouple connectors have one wide blade and
one narrow blade.
Do not force connector in back-
wards. Connect thermocouple to receptacle at top
of instrument as shown in the following illustration.
Thermocouple wiring polarity must be correct. If
readings decrease as the temperature increases,
the thermocouple wires may be reversed. The red
wire is negative for thermocouple wires manufac-
tured in North America.
