Fluke 771 Milliamp Process Clamp Meter\n\nSave time by measuring 4-20 mA signals without breaking the loop\n\nThe Fluke 771 delivers all the basic functionality you would expect in a milliamp clamp meter. It measures 4-20 mA signals without \u201Cbreaking the loop,\u201D allowing you to measure low level DC current without having to take systems offline for troubleshooting, saving downtime and money. You can also use it to measure output signals from transmitters without breaking the loop when maintaining and troubleshooting process and automation equipment. This saves time and avoids disrupting critical processes so you can avoid expensive downtime. You can also measure 10 to 50 mA signals in older control systems using the 99.9 mA range.\n\nAdded convenience\n\nDesigned to make troubleshooting easier, the Fluke 771 includes a detachable clamp that can be attached to the wire you\u2019re testing while you move the meter\u2014connected by the extension cable\u2014to a better viewing ;
