8.0 Trimming and Calibration
The following section provides descriptions and procedures for load cell trimming, scale calibration and serial tag placement.
8.1 Overview and Equipment Required
Load Cell Trimming
Individual load cell signal trimming (equalizing the signal output from each load cell) must be done first along each side of the
scale so all cells on a side have equal signal output. Adjustments are somewhat interactive, so each side should be done at
least twice.
Once that is done, load cell pairs - one from each side - are trimmed as paired sections until each sectional output is equal.
Adjustments to each section should also be done at least twice.

Equipment Required
Both of these trimming operations can be done using a weight cart parked in various locations on the scale. Final verification of
equal output trimming, however, requires test weights to be placed on the deck in various locations.
8.2 Trimming Individual Cells
Connect all load cells to the summing board terminals in the junction box. Connect the main interface cable from the junction
box to the indicator. Power up the indicator.
Turn all load cell potentiometers (individual and section) in the junction box clockwise so all signals are at full strength. Refer to
the junction box instruction manual for proper setup of jumpers and dip switches prior to trimming, then proceed to individual
cell trimming.
