C.3.1 Connecting the RTD to the 4 to 20-mA Transmitter
RTDs should have two common leads and one signal lead. If you are using a 
GE RTD, the wire colors may vary; however, two of the RTD wires will be 
the same color. The wires that are the same color are the common leads and 
the remaining wire is the signal lead.
If you are using your own transmitter, make the necessary connections. If 
you are using the GE DTR, connect the RTD wires to the terminal block 
labeled RTD Inputs. Connect the common and signal wires to the 
appropriate pins as designated on the terminal block label.
IMPORTANT:
The supply and return RTD cables must be the same length 
in order to make accurate temperature measurements. 
When you have completed supply and return connections, proceed to the 
next section.
