Description
Chroma 16502 Milliohm Meter Repair
The Chroma 16502 Milliohm Meter 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.
June Company’s certified technicians repair the Chroma 16502 Milliohm Meter 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 Chroma 16502 Milliohm Meter problems we fix
- 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.
- 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.
FAQs
Do you service instruments past manufacturer support? Yes. Much of what we repair is out of support, which is exactly where component-level work earns its keep.
What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
