Need more hours in your day? Save time by not breaking the loop on 4-20 mA signal measurements with the Fluke 771 Process Clamp Meter.

•Taking mA measurements by removing a wire and breaking the loop
•Calling the control room to isolate a loop
•Testing analog input/output on a console
•Troubleshooting devices with mA inputs and outputs
•Repairing intermittent or erratic 4-20 mA loops
•Going back to the shop to get extra tools

If you need more time in your busy day take a good look at the Fluke 771 mA Clamp Meters. It’s designed to save you time, and money, by eliminating time wasting activities. Now you can troubleshoot and repair 4-20 mA loops without breaking the loop or bringing down the system.

2 AA batteries, soft carry case and user manual.

The Fluke milliamp process clamp meter measures the current up to 99mA. This clamp meter saves you time by measuring 4-20 mA signals without breaking the loop or bringing down the system. 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. This meter contains 2 AA batteries, soft carry case and user manual.
