  Temperature, 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.
