Unstable weight drifting is usually caused by specific environmental interferences:
1. Placing the scale on an uneven surface, touching adjacent items, or positioning it too close to a violently vibrating espresso pump. Weight readings can also fluctuate during the charging process.
2. Critically low battery power.
3. Exposure to strong ambient wind/air currents, hot steam, or placing a boiling-hot vessel directly onto the bare scale surface. Always operate the scale on a flat, sturdy surface away from direct steam, ensure it is properly charged, and always use the included protective silicone heat pad.
