Model 771 Milli-amp Process Clamp Meter - Features and Specifications

 

With the Model 771 you no longer need to lift a wire from a terminal (break the loop) to measure 4 to 20mA which has a direct impact on your maintenance time. With the Fluke 771 there is no need to call a control room to override the control of a process loop when breaking the loop and you save time when testing analog I/O on a PLC if you do not need to check measurements on a console.

Measure 4-20 mA signals without breaking the loop with this new, compact clamp meter for PLC and control systems analog I/O. The detachable clamp with extension cable allows you to take measurements in tight locations, and the built-in spot light illuminates hard to see wires in dark enclosures.

Fluke model 771. Don’t break the loop on 4-20 mA signal measurements
