3.1 Draft Shield
The draft shield was designed with an easy to remove center piece which can be used
as a high quality sample tray. Even with the center piece removed the draft shield will
provide increased protection from rough environments while maintaining weighing
speed. To remove the center piece, rotate counter-clockwise. See Figure 3-1. With the
sample tray firmly in place the unique shape of the draft shield also allows for efficient
stacking of one scale on top of another.
