The Fluke FLK-789FC-MA/KIT is a current loop calibrator used for testing, simulating, and measuring 4–20 mA signals in industrial control systems. It is mainly used by technicians who work with transmitters, PLC inputs, control valves, and process instruments where loop accuracy matters. This kit is built for hands-on field work. It is not bulky or complicated, and it does exactly what a loop calibrator is supposed to do without unnecessary extras.
The 789FC can source, simulate, and measure current, covering most loop testing work in a single handheld device. It helps you check whether a transmitter is sending the correct signal and whether a control system is reading it correctly.
The unit is solid, well-balanced, and easy to operate with one hand. The screen is clear enough to read in workshop lighting and plant environments. Buttons are spaced properly so you do not press the wrong function while working. It is made for repeat testing during routine maintenance, not just occasional calibration work.
It is mainly used in oil and gas, manufacturing, utilities, and automation facilities.
