Adjusting the Off-center Load
If the weighing platform has only 1 load cell, the off-center load is not adjusted in
case of error. The load cell must be replaced.
The off-center load is adjusted only in weighing platforms that have 4 load cells.
Mechanical asymmetries can result in off-center loading errors that exceed
permissible tolerance limits. Such errors must be compensated by soldering resistors
to the PCB in the junction box.
The 4 solder bridges for the resistors are short-circuited at the factory (see the
illustration on the left; note the 4 solder bridges and the sequence of the load cells).
Note: The off-center load is adjusted only in weighing platforms that have 4 load
cells.

To minimize the off-center loading error, use the load cell with the lowest readout
value as a reference. Then adjust the other load cells to this value by adding
resistors.
