Fluke 771 Milliamp clamp meter saves you time by measuring 4-20 mA signals without breaking the loop

The Fluke 771 delivers all the basics. It measures 4-20 mA signals without "breaking the loop", allowing you to measure low level dc current while 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 disruption to the process. For more convenience, the detachable clamp 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.
