726 Users Manual Using Resistance-Temperature Detectors (RTDs) The Calibrator accepts RTD types shown in Table 6. 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. The Calibrator accepts RTD measurement inputs in two-, three-, or four-wire connections, with the three-wire connection the most common. A four-wire configuration provides the highest measurement precision, and two-wire provides the lowest measurement precision.
