8. Mount the Load Disc assembly to the foundation. (See TI
drawings, Appendix D)
a. Gently lower the Load Disc 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 positioning
of the Load Discs. (See Figure 3-2.)
c. Repeat Steps 8a and 8b for the remaining Load Discs.
9. Re-install the Load Disc cable and record the voltage output at
“no- load” condition now that it is in position.
a. If not already done, connect the Load Disc cable to
the KM Test Meter as seen in Figure C-1
Troubleshooting.
b. Turn on the power to the KM Test Meter and set the
Simulate/Test switch to the Test position.
c. Record the no-load output into Figure 3-3 below or
create your own similar table. See the example chart in
Figure 3-5.
d. Assign a number (1, 2, 3, etc.) to the Load Disc and note
it.
e. Repeat steps c and d for all the Load Discs.

7. Inspect the foundation and vessel mounting surfaces that
will mate to the Load Disc 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. Check the surfaces for flatness and angular
misalignment. A baseplate with leveling nuts is
recommended. (See Figure 3-1 below)
