port.
2.2 Installing Components
Refer to the illustration and instructions below to identify and assemble your Discovery balance with its components. All components must be
installed before using the balance.
2.2.1 Assembly
1. Open the side doors of the balance, then Install the Shield, Wind Ring and Pan as shown in the illustration.
2. Place the In-Use cover on the front panel of the balance.
2.3 Selecting the Location
Locate the balance on a firm, steady surface. Avoid locations with excessive air currents, vibrations, heat sources, or rapid temperature
changes.
2.4 Leveling the Balance
Before the balance is used, the feet should be adjusted so that the scale is level with the surface. This will enable accurate weighing. You will
see a level bubble indicator in a small round window inside the weighing compartment. Level the balance by adjusting the leveling feet so the
