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 R 0. The most

common R0 is 100Ω. Most RTDs come in a three- terminal configuration. The calibrator accepts RTD measurement inputs in two-, three-, or four-wire connections. A four-wire configuration provides the highest measurement precision, and two-wire provides the lowest measurement precision.
