Fluke 43B Power Quality Analyzer Calibration and Repair
The Fluke 43B is a handheld power quality analyzer (the updated 43B) combining scope, meter, and power-quality functions (voltage, current, power, harmonics, transients) in one portable instrument. Its accuracy depends on the voltage and current measurement inputs and the acquisition system, so that’s where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 43B for power-quality and electrical-maintenance teams.
Common Fluke 43B problems we fix
- Input-channel faults — a voltage or current input not reading correctly, repaired.
- Readings out of spec — measurement-circuit drift, recalibrated against standards.
- Acquisition / measurement faults — the acquisition system skewing readings, repaired.
- Won’t power on or hold a charge — the aging battery and power section, serviced.
- Display or input faults.
FAQs
My 43B input or reading is off — fixable? Yes. Input and acquisition faults are repairable, then the inputs are recalibrated so power and PQ measurements are accurate, with a NIST-traceable certificate.
Are the inputs verified? Yes — voltage and current inputs are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
