Connect single leaded end of RTD bulb to terminal 17 and the double leaded ends to terminal 16 and 15 (interchangeable) as
shown in Figure 10.2 (a).
Use low resistance copper conductor leads of the same gauge and length. Avoid joints in the cable.
Thermocouple
Connect Thermocouple Positive (+) to terminal 17 and Negative (-) to terminal 16 as shown in Figure 10.2 (b). Use correct type
of extension lead wires or compensating cable. Avoid joints in the cable.
mA / mV / V
Use a shielded twisted pair with the shield grounded at the signal source for connecting mV / V source. Connect common (-) to
terminal 2 and the signal (+) to terminal 1, as shown in Figure 10.2 (c).
