The Fluke 771 milliamp process clamp meter measures mA signals for PLC and control system's analog input/output. The Fluke 771 can also measure 4 to 20 mA output signals from transmitters without breaking the loop. 0.2% accuracy and 0.01 mA resolution and sensitivity make the Fluke 771 one of the best options in it's class.

The Fluke 771 features a hold function that captures and displays changing measurements. The meter has a dual backlit display that shows both mA measurement and percent of 4 to 20 mA span. The measurement spotlight illuminates hard to see wires in dark enclosures. The detachable clamp with extension cable facilitates taking measurements in tight locations.

Fluke 771 milliamp process clamp meters have a 99.9 mA range that measures 10 to 50 mA signals in older control systems. Automatic battery saving features include an automatic power down after 15 minutes and the backlight and spotlight with automatically shut off after 2 minutes.

The Fluke 771 ships complete with soft carrying case and user's manual.
