Fluke 1740 Power Quality Logger Repair

Description

Fluke 1740 Power Quality Logger Repair

The Fluke 1740 (Memobox) is a three-phase power quality logger — it records voltage, current, power, harmonics, and PQ events across all phases (with current probes) for power-quality surveys and load studies, with PC software. Its accuracy depends on the voltage and current measurement inputs, so that’s where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 1740 for energy auditors, facility managers, and PQ teams.

Common Fluke 1740 problems we fix

• Input-channel repair — a phase not reading from its probe, repaired so all phases log.
• Memory-system restoration — lost or corrupt recordings, the recording/memory restored.
• Probe-interface recalibration — current-probe inputs drifting, recalibrated against standards.
• Won’t communicate with the PC software — interface faults, repaired.
• Power or display faults.

FAQs

One phase isn’t logging on my 1740 — fixable? Yes. Input and memory faults are repairable, then all inputs are recalibrated so your PQ logs 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.
