RTD Input
The RTDs described in Appendix A of this manual are recommended for measuring temperature for use
in temperature-compensated gas and liquid calculations, though a 2- or 3-wire RTD may prove functional.
Wiring is essentially the same for all three models, though wire color may vary as indicated. Wire as shown in
Figure 3.5.
