CONNECTING A THERMOCOUPLE
Note: Be sure your instrument setting (J, T, E or K)
matches the thermocouple you are using.
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
E
Purple
Thermocouple connectors have one wide blade and
one narrow blade.
Do not force connector in back-
wards. Connect thermocouple(s) to receptacle at
top of instrument.
If only one thermocouple is being used, it can be
connected to either T1 or T2. The thermometer will
automatically determine which connector is being
used. When two thermocouples are used, connect
one to the T1 connector and one to the T2
connector.
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.
