Hi. Re the schematic printed on the transmitter. Do the solid lines for terminals 1, 3 and 4 mean they must be connected? And dashed line for 2 is optional i.e for a 3 wire RTD.
Get the data sheet from the manufacturer, or on-line. It should tell you what to do for your application.
Heck, email the manufacturer if you have a specific wiring question about your application.
