15: Double module installations contain a middle section. For the middle sections, the eleva-
tion reference is both the absolute level of the main beams with respect to the end sections,
and the equal loading of the loadcells that support the middle of the scale. Adjust the grout
plate leveling screws to level the modules. Alternately, a transit can be used to compare and
maintain elevation, and a tightly stretched mason line.
16: Providing a suitable power supply to connect to the loadcells, measure and record the
mV/V output from each loadcell in the scale. The resulting readings will indicate the current
weight distribution of the scale's deadload among the six (6) points of support. The outputs
will be greater for number's 3 and 4 because there is physically more deadload weight upon
them.

This final grout plate elevation adjustment should be made to match the mV/V outputs of the
load cells to assure correct distribution of the scale's deadload among the six (6) points of
support. Adjust the grout plate leveling screws (equally) to match loadcells 1, 2, 5, and 6.
Then adjust to match loadcells 3, and 4. When this has been completed, ensure each load-
cell grout plate is level to within .015" per foot.

LOGIX technology instrumentation.
