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.
