Megger DLRO100EB Micro-ohmmeter Repair
The Megger DLRO100EB is a 100 A digital low-resistance ohmmeter (DLRO) — a battery-powered (EB) high-current micro-ohmmeter that passes up to 100 A through a connection and measures micro-ohm-level resistance to verify joints, breaker contacts, and bonds in the field. Its character is high-current sourcing plus precision low-resistance measurement, so faults concentrate in the current source, the measurement front-end, the battery, and the connections.
June Company repairs and calibrates the Megger DLRO100EB for substation, switchgear, and field test crews.
Common Megger DLRO100EB problems we fix
- Battery-pack degradation — won’t run a full 100 A test or hold a charge, the battery serviced/replaced.
- Won’t reach test current — the high-current source failing to deliver rated amps, repaired.
- Resistance readings drift or out of spec — the micro-ohm measurement front-end drifting, recalibrated against standards.
- Test-lead / connection faults — the heavy current and sense connections, serviced.
- Display or interface faults.
FAQs
My DLRO100EB won’t hold a charge or reach current — fixable? Yes. Battery and current-source faults are repairable, then the measurement is recalibrated so micro-ohm readings are accurate at test current, with a NIST-traceable certificate.
Can you replace the battery pack? Yes — battery service is routine.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
