4. Setup
4.1. Placement
Place the balance on a firm, level, and stable surface. Ensure the location is free from drafts, vibrations, and rapid temperature changes. Avoid placing it near heat sources or direct sunlight.
4.2. Leveling
The balance must be level for accurate measurements. Adjust the leveling feet located at the bottom of the balance until the air bubble in the spirit level (usually located near the display) is centered within the circle.

- Plug the adapter into a suitable electrical outlet.
4.4. Initial Power On and Zeroing
Press the ON/ZERO/OFF button to turn on the balance. Allow a brief warm-up period (typically 1-2 minutes) for the balance to stabilize. The display should show '0.00g' or '0.000g'. If not, press the ON/ZERO/OFF button again to zero the display.
