0V to 28V; 0mA to 24mA; 0.02% accuracy. The Fluke 705 loop calibrator is a cost-effective, integrated solution for current-loop calibration, repair and maintenance. The Fluke 705 features mA sourcing, simulation and measurement, has 0.02% accuracy and 0.001 mA resolution. Fluke 705 loop calibrators can simultaneously display mA and % of span readings and has selectable step or ramp outputs. The Fluke 705 has a 24V loop supply with mA measure and 0V DC to 28V DC measurement to check loop voltage.
