Fluke 321 Clamp Meter Calibration and Repair
The Fluke 321 is a compact digital clamp meter measuring AC current (via the clamp) plus AC/DC voltage, resistance, and continuity for electrical troubleshooting. Its accuracy depends on the clamp jaw/current sensor and the measurement circuitry, which is where repair and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 321 for electricians and maintenance technicians.
Common Fluke 321 problems we fix
- Clamp-jaw / current-sensor faults — a damaged or misaligned jaw giving erratic current readings, repaired and recalibrated.
- Current measurement out of spec — the measurement drifting, recalibrated against standards.
- A function dead — a measurement path failed, repaired.
- Display or battery faults — repaired.
- Terminal or function-switch faults.
FAQs
My 321 clamp reading is off — fixable? Yes. Jaw and measurement faults are repairable, then the clamp meter is recalibrated so current and other readings are accurate, with a NIST-traceable certificate.
Is the clamp verified? Yes — the jaw and all 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.
