753/754 Users Manual Resistance-Temperature Detectors (RTDs) The Product accepts RTD types shown in Table 8. RTDs are characterized by their resistance at 0 °C (32 °F), which is called the "ice point" or R0. The most common R0 is 100 Ω. A large number of RTDs come in a three-terminal configuration. The Product accepts RTD measurement inputs in two-, three-, or four-wire connections. See Figure 17. A four-wire configuration gives the highest measurement precision, and two-wire gives the lowest measurement precision. Table 8.
