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.

Measure mA signals for PLC and control system analog I/O without breaking the loop
• Measures low level dc current
• Correlate process indication with real physical value

Measure output signals from transmitters without breaking the loop
• Maintain and troubleshoot process and automation equipment without breaking the loop
• No disruption to the process

Detachable clamp with extension cable
• Measurements in tight locations
• Enables measurements in difficult situations

Measurement Spotlight
• Illuminates hard to see wires in dark enclosures
