PT1000
By default, the Pt1000 measurement is a 3-wire connection but you can
change it to a 4-wire connection on the Advanced user level by
changing the measurement type. Typically, you do not need to change
the predefined Pt1000 parameters. Only the data validation parameters
can vary, depending on the installation site. You can see all parameters
as an Advanced user.
See Chapter 7, Technical Data, on page 337 for the example wiring
diagrams for 3-wire and 4-wire connections of the Pt1000 probe.
