The Sugawara Labs MA‑72 Auto Anderometer is a high‑speed bearing vibration test system that automatically measures front and back side vibrations of bearings using twin spindles and FFT analysis. Common failure points for this class of equipment include power supply instability, spindle motor wear or misalignment, sensor drift or cable insulation breakdown, and firmware corruption in the control board. Begin troubleshooting by verifying 48 V DC rail continuity and proper voltage levels to the drive electronics; inspect the spindle bearings and alignment marks for wear or debris; check all sensor cables for visible damage and confirm that the encoder/ADC signals are within spec on an oscilloscope.[oss-gpt-20b]
