Megger 247002-11 Low Resistance Ohmmeter Repair
The Megger 247002-11 is a digital low-resistance ohmmeter (DLRO) — it passes a controlled test current through a connection and measures low resistance (milliohm/micro-ohm range) using a 4-wire Kelvin method to verify joints, contacts, and bonds in substations and switchgear. Its character is current sourcing plus precision low-resistance measurement, so faults concentrate in the current source, the measurement front-end, and the test-lead connections.
June Company repairs and calibrates the Megger 247002-11 for substation, switchgear, and transformer-maintenance crews.
Common Megger 247002-11 problems we fix
- Current-source drift — the test-current source drifting so resistance readings are off, repaired and recalibrated.
- Resistance readings out of spec — the measurement front-end drifting, recalibrated against standards.
- Test-lead / Kelvin connection faults — the 4-wire leads and connections, serviced.
- Won’t power on or hold a charge — battery/power faults.
- Display or interface faults.
FAQs
My 247002-11 readings drift — fixable? Yes. Current-source and measurement faults are repairable, then recalibrated so low-resistance readings are accurate, with a NIST-traceable certificate.
Are the test leads checked? Yes — the Kelvin connections are verified.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
