Page 20: Using Resistance Thermometer Detector (Rtd)
4.2 Using Resistance Thermometer Detector (RTD) The calibrator accepts Pt100, Pt1000, Cu50 and Cu100, etc. The calibrator accepts RTD measurements 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. -
