Thermocouples
CP1W-TS001/CPM1A-TS001
Either K or J thermocouples can be connected, but both of the thermocouples
must be of the same type and the same input range must be used for each.
CP1W-TS002/CPM1A-TS002
Either K or J thermocouples can be connected, but all four of the thermocou-
ples must be of the same type and the same input range must be used for
each.
Note When using a Temperature Sensor Unit with a thermocouple input, observe
the following precautions:
• Do not remove the cold junction compensator attached at the time of
delivery. If the cold junction compensator is removed, the Unit will not be
able to measure temperatures correctly.
• Each of the input circuits is calibrated with the cold junction compensator
attached to the Unit. If the Unit is used with the cold junction compensator
from other Units, the Unit will not be able to measure temperatures cor-
rectly.
• Do not touch the cold junction compensator. Doing so may result in incor-
rect temperature measurement.
