Description
Fluke 771 Process Clamp Meter Calibration and Repair
The Fluke 771 is a milliamp process clamp meter that measures 4–20 mA loop current without breaking the loop (via a clamp), for troubleshooting process control loops. Its accuracy depends on the milliamp clamp/measurement sensor and the mA source/measure circuitry, which is where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 771 for process-control and instrumentation technicians.
Common Fluke 771 problems we fix
- Clamp-sensor faults — the milliamp clamp not measuring loop current correctly, repaired and recalibrated.
- mA measure/source out of spec — the measurement or sourcing drifting, recalibrated against standards.
- A function dead — an input/output path failed, often after a miswire, repaired.
- Display or battery faults — repaired.
- Terminal or connector faults.
FAQs
My 771 clamp or mA reading is off — fixable? Yes. Clamp and source/measure faults are repairable, then the meter is recalibrated so loop measurements and sourcing are accurate, with a NIST-traceable certificate.
Is the clamp verified? Yes — the clamp and mA functions are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
