Calibration: Execute tare()for zero-point calibration (no load). Use set_scale()with a known weight (e.g., 500g) to calculate AD-to-weight ratio. Save parameters to non-volatile memory for power-cycle retention. Q2: Data instability under vibration? Solution: Enable dynamic digital filtering (register 0x0D). Reduce sampling rate to 10Hz for high-vibration environments. Q3: Maximum supported load cells?
