Fluke 1738 Power Logger Repair and Calibration
The Fluke 1738 is a three-phase advanced power quality logger — it records voltage, current, power, energy, and PQ events over time using flexible current probes, for energy studies and power-quality investigations. Its accuracy depends on the voltage and current measurement inputs, so that’s where service and calibration focus.
June Company repairs and calibrates the Fluke 1738 for energy auditors, PQ consultants, and facility engineers.
Common Fluke 1738 problems we fix
- Current-input or probe channel faults — a phase not reading from its flex/clamp probe input, repaired so all phases log.
- Voltage/current readings out of spec — measurement-circuit drift, recalibrated against standards.
- Won’t log or store data — recording or memory faults, restored.
- Won’t power on or charge — power-supply or battery faults.
- Won’t connect to software — interface faults.
FAQs
One phase isn’t logging — fixable? Yes. Input-channel faults are repairable, then all inputs are recalibrated so your power and PQ data 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 submit a service request.
