Fluke 1577 Insulation Multimeter Calibration and Repair
The Fluke 1577 is an insulation multimeter — it combines a digital insulation resistance tester (megohmmeter, to 1000 V) with a full true-RMS multimeter (AC/DC voltage, resistance, continuity) in one handheld for electrical troubleshooting. Its accuracy depends on the high-voltage insulation generator and the DMM measurement circuitry, which is where repair and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 1577 for electricians and maintenance teams.
Common Fluke 1577 problems we fix
- Insulation-test / HV generator faults — won’t reach the insulation test voltage or the reading drifts, repaired and recalibrated against standards.
- DMM function faults — a multimeter function dead or inaccurate, often after an overload, repaired and recalibrated.
- A function dead — an input or range-circuit fault, repaired.
- Input protection blown — repaired after a miswire.
- Display or battery faults.
FAQs
My 1577 insulation test or meter reads wrong — fixable? Yes. HV-generator and DMM faults are repairable, then every function is recalibrated so insulation and meter readings are accurate, with a NIST-traceable certificate.
Do you calibrate both functions? Yes — insulation and multimeter functions are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
