Figure 3-141. Ratio Beam Vane Slotted Area.
Carefully place the Ratio Beam into position on the Load Cell. Do not install the
6.
screws yet. (See Figures 3-143 and 3-144.)
Figure 3-143. Replacing the Ratio Beam.
Insert a Centering Pin to hold the
7.
Ratio Beam in position, as shown in
Figure 3-145.
The Centering Pin also helps to
avoid stressing the internal
flexures. If the internal flexures are
stressed in the process of
reassembly, the Load Cell may be
ruined, and would then need to be
replaced.
