The Fluke 712B RTD Calibrator is a handheld, battery-operated instrument designed to measure and source various Resistance-Temperature Detector (RTD) signals. It features an isolated channel for measuring 4-20 mA current and supports multiple RTD types including Pt100, Pt200, Pt500, Pt1000, Ni120, and Cu variants. The device allows users to simulate RTDs, scale the mA channel to temperature, and perform step or ramp mode operations.
