FIGURE 2-7
RTD Input
Connections are shown for 3 wire and 2 wire RTD's. If a three wire device is used, install the
common wires to terminals 1 and 5. If a two wire device is used, install a jumper between
terminals 1 and 5.
FIGURE 2-8
Volt, Millivolt and Milliamp Input
Make volt, millivolt or milliamp connections as shown below. Terminal 3 is positive and
terminal 1 is negative. Milliamp input requires a shunt resistor be installed across the input
terminals as shown. 4-20mA input are accommodated by setting up the instrument for either
10 to 50mVDC or 1 to 5VDC input. Make sure that the appropriate resistor value is used.
Terminal 3 is positive and terminal 1 is negative. (.1% resistors recommended.) (Continued
