Apparent drift during stationary states typically indicates **gimbal pivot friction**, contamination along the electrical slip-ring wipers, or that the internal motor hasn't reached its full operational speed. Ensure the input motor winding line voltage meets nominal ratings and allow a minimum **5-minute spin-up window** for the momentum wheel to stabilize before capturing orientation baselines.\n    \u003c\/p\u003e\n    \n    \u003cp style=\"margin-bottom: 10px;\"\u003e\u003cstrong\u003eQ2: What is the correct wiring safety protocol to ensure clean output signals free of high-frequency aircraft motor hum?\u003c\/strong\u003e\u003c\/p\u003e\n    \u003cp style=\"margin-bottom: 15px; padding-left: 15px; border-left: 3px solid #16c8c8;\"\u003e\n      A2: Potentiometer-based displacement gyros share physical spaces with high-current power grids. To prevent induction noise from distorting attitude telemetry metrics, use independent twisted-pair shielded cables for the Pitch\/Roll wiper signals. Ground the exterior drain shield wire at a single reference point on the ADC chassis side only. Never allow the signal wires to run parallel to active high-amperage electronic speed controller (ESC) power lines.\n    \u003c\/p\u003e\n    \n    \u003cp style=\"margin-bottom: 10px;\"\u003e\u003cstrong\u003eQ3: How can a technician verify if the internal bi-axial potentiometer tracking tracks are scored or worn on a used unit?\u003c\/strong\u003e\u003c\/p\u003e\n    \u003cp style=\"margin-bottom: 15px; padding-left: 15px; border-left: 3px solid #16c8c8;\"\u003e\n      A3: Isolate all electrical connections from power grids. Attach a high-resolution digital multimeter configured for resistance measurement (ohms) across the wiper and common output pins. Slowly tilt the canister manually along the specific target axis. The resistance profile must scale in a smooth, continuous linear progression. Any sudden resistance jumps or open-loop readouts (OL) confirm localized contact track scoring, requiring specialized lab component servicing.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- 7.
