As an RTD is a low-impedance signal, the 9-core should be fine.

Agree with PWSlack, especially since the Operator's Manual recommends it.

I would suggest you to use shielded triad instrument cable. In this cable, a bundle of three conductors (called triad) are grouped together and shielded. There may be a numbers of such bundles in a cable. You need a cable of at least three numbers of triad.

Here are some links for the triad:
