Dear all,
I am working on PT-100 3-wire connet CR1000
CR1000→PT-100 3-Wire
Hi→ A
Lo→ no connet
G→ B
G→ B
A.B bridging 1K Ohm.
Connet So correctly ??
Thanks campbell all

prob not correct..
You need to send a constant current through the temperature depended resistor (PT100) to measure a voltage drop that will correlate with the temperature.
See CS 3-wire half bridge module that does exactly that:

And then read the CR200 manual about bridge measurements on page 41:

Dear Nico
Thanks you
I will try connet.
