HVACDiagnostics & Troubleshooting3MediumField Technician$ implied
A technician cannot reliably determine whether a motor has a ground fault or internal defect using only a standard multimeter, lacking a megger tester to confirm.
Standard multimeter cannot reliably detect motor ground faults; a megger tester is needed but not always available, leaving technicians uncertain and resorting to risky manual tests.

Workarounds Described
- Manually disconnecting motor from drive and hooking up to contactor to test
- Using multimeter and interpreting OL readings and continuity beeps without certainty
Implied Software Gaps
- A device that performs a professional-grade megger test without requiring separate equipment
- Guided diagnostics software that interprets multimeter readings and gives a clear diagnosis
App Concept
MotorInsight Pro
