A load cell summing box (also known
as a J-box) accepts inputs from
multiple load cells and combines
their outputs into one output that
represents the total load. All load
cells should have the same capacity
and outputs within 3.2% of each
other. For larger variances, resistors
must be added. Load cells that are
trimmed to 0.25% interchangeability
or that have output tolerances of
less than ±3.2% will work without
additional resistors.
