Description

Fluke 438 Power Quality and Motor Analyzer Repair

The Fluke 438 is a three-phase power quality and motor analyzer — it adds mechanical motor measurements (torque, speed, efficiency, derived without sensors) to Class-A power-quality analysis across all phases (with current probes). Its accuracy depends on the voltage and current measurement inputs and the motor-analysis computation, so that’s where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 438 for power-quality, motor, and reliability teams.

Common Fluke 438 problems we fix

  • Motor-analysis faults — the torque/speed/efficiency computation returning wrong results from a measurement fault, repaired and recalibrated.
  • Current-input or probe channel faults — a phase not reading from its probe, repaired so all phases measure.
  • Readings out of spec — measurement-circuit drift, recalibrated against standards.
  • Won’t power on or hold a charge — battery and power faults.
  • Display or input faults.

FAQs

My 438 motor results or a phase is off — fixable? Yes. Input and analysis faults are repairable, then all inputs are recalibrated so power, PQ, and motor measurements are accurate, with a NIST-traceable certificate.

Are the current inputs verified? Yes — checked against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
