2-Wire RTD Inputs
If using a 2-wire RTD input, use heavier gauge
leadwires to reduce leadwire resistance. Any
leadwire resistance adds directly to sensor
resistance, thus adding error to the process
temperature measurement. It is also necessary
to jumper terminals 8 and 9 on the instrument to
complete a 2-wire hookup.
