Fluke 771 Milliamp Process Clamp Meter
The Fluke 771 is a milliamp process clamp meter that measures 4-20 mA signals without breaking the loop. Instead of disconnecting wires to insert a meter in series, you clamp around the conductor and read the signal directly. That makes it a fast, non-invasive tool for checking and troubleshooting process control loops while the system stays live.
Brand and standards
Fluke is one of the most trusted names in electrical test and measurement, and Powerpoint Engineering is an authorised Fluke distributor in Ireland. The 771 is purpose-built for process control, automation and electronic monitoring work, where a 4-20 mA reading needs to be quick, repeatable and taken without interrupting the loop. As an authorised distributor, Powerpoint also calibrates Fluke instruments in its own laboratory, so your 771 can be kept traceable throughout its working life.
Applications
The 771 suits anyone who installs, commissions or maintains 4-20 mA process loops:
- Troubleshooting process control loops without breaking the circuit
- Checking 4-20 mA output from transmitters and sensors
- Commissioning and fault-finding on automation and monitoring systems
- Reaching wires and panels in tight enclosures using the detachable clamp and extension cable

FAQs
Can the Fluke 771 measure mA without breaking the loop?
Yes. That is the whole point of the 771. You clamp it around the conductor to read 4-20 mA signals without disconnecting any wires, so the loop stays live. This avoids the downtime and the risk of system upset that comes with detaching wires for a series measurement.
What kind of work is the Fluke 771 for?
It is aimed at process control, automation and electronic monitoring. Typical jobs are checking transmitter and sensor outputs, troubleshooting 4-20 mA loops, and commissioning or maintaining process systems where you need a quick, non-invasive current reading.
Can Powerpoint Engineering calibrate my Fluke 771?
Yes. Our in-house calibration and repair laboratory services Fluke process tools and issues traceable certificates. Speak to our calibration team to book your 771 in and keep its readings reliable.
