Fluke 1507 Insulation Tester Repair
The Fluke 1507 is a compact handheld insulation resistance tester (megohmmeter) — it applies selectable DC test voltages (to 1000 V) and measures insulation resistance, with PI and DAR diagnostic ratios, for motor, cable, and equipment testing. The hardworking part is the high-voltage generator, so that’s where most faults originate, along with the measurement and battery.
FlukeMeterRepair.com repairs and calibrates the Fluke 1507 for electrical-maintenance and test teams.
Common Fluke 1507 problems we fix
- DAR / PI diagnostic faults — the DAR or PI ratios not calculating correctly, restored.
- HV generator faults — won’t reach the selected test voltage or output is low, repaired for full rated voltage.
- Measurement drift — insulation-resistance readings drifting, recalibrated against standards.
- Display or battery faults — repaired.
- Terminal or input faults.
FAQs
My 1507 DAR or megohm reading is off — fixable? Yes. HV-generation and measurement faults are repairable, then the tester is recalibrated so insulation readings and diagnostics are accurate, with a NIST-traceable certificate.
Is the HV output verified? Yes — test voltage and resistance ranges are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
