Description
Megger DLRO100H Micro-ohmmeter Repair
The Megger DLRO100H Micro-ohmmeter is a low resistance ohmmeter – it injects a known current and measures the resulting millivolts through separate sense leads, because at micro-ohm level the test leads themselves would otherwise dominate the measurement. That four-wire arrangement is the whole instrument.
Certified technicians at June Company service the Megger DLRO100H Micro-ohmmeter for substation technicians, motor shops, utility maintenance crews, and quality departments. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Megger DLRO100H Micro-ohmmeter problems we fix
- Sense lead or Kelvin clamp faults.
- Readings drifted out of tolerance – corrected and verified against reference standards.
- Temperature compensation errors.
- Battery, charging or power faults.
- Display, keypad or front-panel faults.
- GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
- Readings inconsistent between repeat measurements – usually the current clamps or sense leads rather than the instrument – contact resistance is a large share of what is being measured at these levels.
- Test current not reaching the set value.
