Fluke 1550C FC Insulation Tester Repair

Description

Fluke 1550C FC Insulation Tester Repair

The Fluke 1550C FC is a 5 kV insulation resistance tester with Fluke Connect that applies selectable DC test voltages up to 5 kV and measures very high insulation resistance with diagnostic tests, sharing results wirelessly. The hardworking part is the high-voltage generator, so that’s where most faults originate.

FlukeMeterRepair.com repairs and calibrates the Fluke 1550C FC for motor-shop technicians, electrical maintenance crews, and cable-testing contractors.

Common Fluke 1550C FC problems we fix

• Battery degradation — won’t hold a charge for high-voltage tests, the battery serviced.
• HV generator recalibration — won’t reach the selected test voltage, repaired and recalibrated.
• Measurement-circuit repair — insulation-resistance readings drifting, recalibrated against standards.
• Display, terminal, or battery faults — repaired.
• Won’t power on — power faults.

FAQs

My 1550C FC won’t reach test voltage — fixable? Yes. HV generator faults are the usual cause and they’re repairable, then verified so the tester delivers full rated voltage and your readings are valid, with a NIST-traceable certificate.

Is the measurement verified? Yes — test voltage and resistance are checked against our standards.

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