Proper setup is crucial for accurate measurements.

1. 놓기: Place the balance on a stable, vibration-free surface, away from direct sunlight, air currents, and significant temperature changes.
2. 수평 조정: Use the adjustable leveling feet at the base of the scale to center the bubble in the built-in level indicator. This ensures the weighing pan is perfectly horizontal.
3. 집회: Carefully place the stainless steel weighing pan onto the center of the weighing platform. Ensure the glass draft shield is properly assembled around the weighing area.
4. 전원 연결: Connect the power adapter to the balance and plug it into an AC 100V-240V power outlet. Alternatively, the scale can be powered by 4x1.5V batteries (not included) for portable use.
5. 워밍업 시간: After powering on, allow the balance to warm up for at least 30 minutes before making critical measurements. This stabilizes the internal components for optimal accuracy.
