Save time by measuring 4-20 mA signals without breaking the loop

The Fluke 771 delivers all the basic functionality you would expect in a milliamp clamp meter. It measures 4-20 mA signals without “breaking the loop,” 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.

Added convenience

Designed to make troubleshooting easier, the Fluke 771 includes a detachable clamp that can be attached to the wire you’re testing while you move the meter—connected by the extension cable—to a better viewing position. This is especially helpful for taking readings in tight locations. With the dual backlit display showing both the mA measurement and the percent of a 4 to 20 mA span you can quickly understand what your system is doing, and a built-in LED spotlight lets you illuminate hard to see wire in dark enclosures. You can also capture and display changing measurements using the Hold function making it easier to verify and record measurements.
