    What to do if A&D HR-250AZ show a stability error?
    • B
      Brenda GilbertAug 21, 2025
      If your A&D Scales display a stability error, it is likely due to an environmental problem. To resolve this, prevent vibration, drafts, temperature changes, static electricity, and magnetic fields. Refer to section '3. PRECAUTIONS' for detailed information on the operating environment and section '7. RESPONSE ADJUSTMENT' for adapting the balance to the environment. To return to the weighing mode, press the CAL key.
