The CSC200 can input or output any one of 17 different RTD types including
ohms. Operation in the input mode includes 2, 3 and 4 wire RTD's and YSI
Series 400 Thermistors. When operating in the output mode the CSC200
can simulate a RTD output into virtually all transmitters and RTD input
devices including pulsed excitation current instruments.
4.1 RTD Input (measure) Mode Operation
To operate the CSC200 in the input mode refer to Figure 3 for the proper
input connections and proceed as follows:
1) Select the RTD mode by pressing the "TC/RTD" key.
