Description

Fluke 1503 Insulation Tester Repair

The Fluke 1503 is a handheld insulation resistance tester (megohmmeter) — it applies selectable DC test voltages (to 1000 V) and measures insulation resistance, with polarization-index diagnostics, 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 1503 for electrical-maintenance and test teams.

Common Fluke 1503 problems we fix

  • Megohm / measurement faults — insulation-resistance readings drifting or wrong, recalibrated against standards.
  • Polarization-index faults — the PI diagnostic not calculating, restored.
  • HV generator faults — won’t reach test voltage or output is low, repaired for full rated voltage.
  • Display or battery faults — repaired.
  • Terminal or input faults.

FAQs

My 1503 megohm or PI reading is off — fixable? Yes. HV-generation and measurement faults are repairable, then the tester is recalibrated so insulation readings 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.
