Fluke 705 Loop Calibrator

The Fluke 705 Loop Calibrator is an integrated, budget-friendly solution for technicians who need to calibrate, maintain, and troubleshoot milliamp loops efficiently. Designed with a large, easy-to-read display and a simple pushbutton interface, the 705 ensures smooth operation even in demanding field conditions.

This calibrator supports mA sourcing, simulation, and measurement, delivering an impressive ±0.02% accuracy and 0.001 mA resolution for highly reliable results. It offers simultaneous mA and percentage span display, simplifying loop testing and calibration tasks.

For enhanced usability, the Fluke 705 includes selectable step and ramp functions that allow smooth outputs for valve slewing and loop testing. The integrated 24 V DC loop power makes it possible to power transmitters while measuring current, removing the need for external equipment. Additionally, it can measure up to 28 V DC loop voltage, enabling quick diagnostics without requiring a separate digital multimeter.

Technicians benefit from the “Span Check” feature, which quickly verifies zero and span points, while the pushbutton 25% steps make linearity checks fast and simple. The unit runs on a single 9V battery, designed for quick swaps without breaking the calibration seal, and supports default startup modes of 0–20 mA or 4–20 mA.

Built for field durability, the Fluke 705 comes with a protective yellow holster and test lead storage, ensuring portability and protection. Compact, reliable, and easy to operate, the Fluke 705 is an excellent choice for process technicians seeking efficiency and accuracy in loop calibration.
