7. Mount the LD3xi/LD3xiC assembly to the foundation. (See TI drawings,
Appendix D)
a. Lower the LD3xi/LD3xiC to the foundation. Take
care to align the mounting holes with the foundation
mounting holes/studs.
b. Install the bolts and nuts as required. DO NOT fully
tighten the bolts at this time. Leave a 1/4-inch gap
between the nut and the washer to allow for positioning
of the Load Discs. (See Figure 3-2.)
c. Repeat Steps 7a and 7b for the remaining Load Discs.
8. Record the voltage output at “no-load”condition now that it is in
position.
a. Assign a number (1, 2, 3, etc.) to the load disc and make a
note of it.
b. Measure the output of load cell..
c. Repeat steps a and b for all the Load Discs.

5. Raise the vessel.
6. Inspect the foundation and vessel mounting surfaces that
will mate to the LD3xi/LD3xiC plates.
a. Check the mounting hole locations and size on both
the foundation base and the vessel foot pad. (Refer
to the TI drawings, Appendix D.)
b. Also check the surfaces for flatness and angular
misalignment. A baseplate with leveling nuts is
recommended. (See Figure 3-1)
