Fluke 771 milliamp clamp meter grey handheld body with tapered jaw and digital display

Fluke

Fluke 771 Milliamp Clamp Meter 0.2% accuracy 0.01mA resolution

SKU CH-191Y-F2HCX

Measures 4-20 mA loop current without breaking the circuit, delivering 0.2% accuracy and 0.01 mA resolution for fast troubleshooting

  • Measure 4-20 mA loops without breaking the circuit
  • 2 % accuracy gives reliable readings for critical signals
  • 01 mA resolution detects small current changes
  • Saves time on troubleshooting analog I/O and intermittent loops
  • Clamp design allows in-circuit testing without system shutdown

Purpose and users

The Fluke 771 Milliamp Clamp Meter measures 4-20 mA process signals without breaking the loop. It is built for technicians who maintain industrial control systems and need fast, non-intrusive current readings on live circuits.

Build quality and daily use

The clamp jaw opens wide enough to encircle standard signal wires, letting you take a reading without disconnecting conductors. A clear display shows the measured value instantly, reducing the time spent on each troubleshooting step in the field.

Deciding specification

Accuracy of .2% with .01 mA resolution determines whether this meter meets your calibration requirements. If your procedures demand tighter uncertainty, this model will not satisfy them.

Questions about this item

What current range does the 771 cover without breaking the loop?

It measures 4-20 mA signals directly through the clamp jaw, so the circuit stays live during testing.

What jaw opening is needed to fit around typical process wiring?

The clamp head accepts standard 4-20 mA loop conductors used in panel and field installations.

How do you take a reading without opening the circuit?

Clamp the jaws around a single conductor, align the arrow with current flow, and read the mA value on the display.
