CP1E CPU Unit Hardware User’s Manual(W479)
(b) CP1W-TS002
Up to four K or J thermocouples can be connected to the CP1W-TS002, but all four
thermocouples must be the same type and the same input range.
Precautions for Correct Use
Precautions for Correct Use
When connecting a thermocouple input, observe the following precautions:
•
Do not remove the cold junction compensator attached at the time of delivery. If the cold junc-
tion 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 correctly.
•
Do not touch the cold junction compensator. Doing so may result in incorrect temperature
measurement.
(2) Platinum Resistance Thermometers
(a) CP1W-TS101
One or two Pt or JPt platinum resistance thermometers can be connected to the
CP1W-TS101, but both of the thermometers must be of the same type and the same
input range must be used for each.
