Fluke 707 Loop Calibrator
The Fluke 707 Loop Calibrator is a reliable, compact tool designed for current loop testing in industrial settings. It simplifies calibration, maintenance and repair tasks with a fast, tactile Quick Click knob that enables one-handed operation. Designed for convenience, it fits easily into your workflow without sacrificing precision or performance.
With ±0.015% accuracy and 1µA resolution, the Fluke 707 delivers trusted results during current sourcing, measurement and simulation. It can generate and read current up to 24mA, as well as test voltage levels up to 28V. Users can quickly verify loop behaviour and troubleshoot instrumentation without carrying additional tools. A built-in 24V loop supply powers transmitters during testing, streamlining on-site diagnostics.
Fast, Accurate Loop Testing
The Fluke 707 features selectable ramp modes, including slow, fast, and step ramp, to provide smooth transitions for valve slewing or functional loop tests. With push-button access to 25% steps, users can easily perform linearity checks, while the 0–100% span check ensures reliable zero and span confirmation. The large backlit display offers clear simultaneous readouts in mA and percentage format, speeding up interpretation.
Built for Practicality and Performance
With a sturdy design and low weight, the Fluke 707 is ideal for everyday use. It includes HART mode for use with HART tools and allows smooth integration into process environments. A single 9V battery powers the unit and can be changed without affecting accuracy. From setup to ramp testing, every feature is built for speed, safety, and ease.
