Leveling/Shimming for the Leveling Top plate
Adapter, Leveling Base Adapter Plate, and the
Anyadapter Plate
1. Based on the Weight Distribution Chart and visual
inspection, raise the leveling nut to adjust the top plate
until the weight distribution falls within the weight
distribution guidelines (See page 3-4). Check for gaps and
use shims as required.
(Objects and support members may cause the weight to be
distributed unevenly. Shimming will involve some judge-
ment.)
2. Gently lower the vessel and measure the dead weight
output and the output change of all of the Load Discs
to see how they are affected. (See Weight Distribution
Chart page 3-3.)
3. Repeat Steps 1and 2 until you have achieved the
desired output change of all of the Load Discs.
(Since the output of each load cell may vary, the change
from ‘no load’ to ‘dead weight’ being equal is more
important than the absolute value. )
Note: Shimming the plates of
one Load Disc will probably
affect the weight distribution
on the Load Disc located on
the opposite side. Keep this in
mind while shimming.
CAUTION: If you
need to raise the
vessel or one vessel
leg after installation,
loosen the bolts on all
Load Discs to prevent
overloading.
