Fluke 715 – Volt/mA Loop Calibrator

The Fluke 715 Volt/mA Loop Calibrator measures and sources voltage and current loop signals for process control and automation applications. Built on Fluke's 80 Series platform, this instrument delivers 0.01% to 0.015% accuracy across multiple ranges with a durable, field-hardened design rated for dust and splash environments. The 715 combines measurement, sourcing, and simulation functions in a single portable package, powered by a single 9V alkaline battery with extended runtime.
