RTD Input

Make RTD connections as illustrated below. For a three wire RTD, connect the resistive leg
of the RTD to terminal 3, and the common legs to terminal 1 and 5. For a two wire RTD,
connect one wire to terminal 1 and the other wire to terminal 3 as shown below. A jumper
wire supplied by the customer must be installed between terminals 1 and 5. Be sure that the
input conditioning jumpers are properly positioned for an RTD input. See
Appendix A-2 (page 65) and A-3 (page 66 and 67).

Volt, mV, mADC Input
Make volt, millivolt and milliamp connections as shown below. Terminal 3 is positive and
terminal 1 is negative. Milliamp input requires a 250 ohm shunt resistor (supplied with the
instrument) installed across the input terminals and by configuring the instrument for either 0
to 5 or 1 to 5 VDC input. If desired, milliamp DC input can be facilitated by installing an
optional 2.5 ohm resistor across the input terminals and configuring the instrument for either 0
to 50 or 10 to 50 mVDC. Be sure that the input conditioning jumpers are properly positioned
for the input type selected. See Appendix A-2 (page 65) and A-3 (page 66 and 67).
