Fluke 1550B Calibration

Description

Fluke 1550B Insulation Tester Calibration and Repair

The Fluke 1550B is a 5 kV insulation resistance tester (megohmmeter) — it applies selectable DC test voltages up to 5 kV and measures very high insulation resistance with diagnostic tests (PI/DAR) for motors, cables, and high-voltage apparatus. The hardworking part is the high-voltage generator, so that’s where most faults originate. (This is the calibration listing for the 1550B.)

FlukeMeterRepair.com repairs and calibrates the Fluke 1550B for motor shops and electrical maintenance crews.

Common Fluke 1550B problems we fix

• HV generator recalibration — won’t reach the selected test voltage, repaired and recalibrated so it hits full 5 kV.
• Insulation-resistance measurement out of spec — the measurement drifting, recalibrated against standards.
• Diagnostic-test (PI/DAR) faults — not calculating, restored.
• Display, battery, or terminal faults — repaired.
• Won’t power on — power faults.

FAQs

My 1550B won’t reach 5 kV — fixable? Yes. HV generator faults are repairable, then verified so the tester delivers full rated voltage and your readings are valid, with a NIST-traceable certificate.

Are the diagnostics verified? Yes — PI/DAR are checked along with recalibration.

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