The Fluke 707 Loop Calibrator is a high-performance tool for calibrating, repairing, and maintaining 4-20mA current loops, allowing users to measure, source, and simulate current up to 24mA. It features a one-handed, quick-click rotary button for fast and easy adjustments, a simultaneous display of both mA and % of span, and offers options for stepped or ramped outputs for tasks like linearity testing. It also includes a 24V loop supply, simplifying setup for many common tasks. Key functions and features Calibration: The device is used to calibrate current loops, ensuring they are functioning : It can act as a source to provide a 4-20mA signal or simulate a sensor's output to test a control system.
