Fluke 1746/B Power Logger Repair

Description

Fluke 1746/B Power Logger Repair

The Fluke 1746/B is a three-phase power quality logger (1740 series, B-kit configuration) that records voltage, current, power, energy, harmonics, and PQ events to IEC 61000-4-30 Class S across all phases with flexible current probes. 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 1746/B for energy auditors, facility managers, and power-quality teams.

Common Fluke 1746/B problems we fix

• Voltage input-channel damage — a voltage input damaged by an over-range event, repaired so all phases log.
• Current-probe channel faults — a current input not reading from its probe, repaired.
• Readings out of spec — measurement-circuit drift, recalibrated against standards.
• Won’t communicate or upload — interface/connectivity faults, repaired.
• Power or display faults.

FAQs

One phase isn’t logging on my 1746/B — fixable? Yes. Input-channel faults are repairable, then all inputs are recalibrated so your 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.
