Adjusting the Weighing Platform

Adjusting the Off-center Load

If the weighing platform has only one load cell, the off-center load is not adjusted

in case of error; rather, the load cell must be replaced.

The off-center load is adjusted only in weighing platforms that have four load

cells.

Procedure (Example Illustrated on the Left)

– Place the test weight (12.5 t) on the weighing platform and write down the

weight values measured.

– The load cell with the lowest weight value (12450 ) is the reference load cell.

This load cell does not require adjustment.

– Calculate the difference between the weight value registered by this load cell

and those registered by the other load cells.

– Plot the point of intersection of the calculated off-center load difference

(x-axis) and the test weight (see page 75).

– The adjustment resistance (total) and the best resistor combination can be read

from the y-axis (see the diagram on page 75).

In the example given here, load cell 3 has an off-center loading error of 80 kg,

which yields an adjustment resistance of 1.5 ohm + 0.82 ohm.

– Depending on the resistor combinations of each individual load cell, the

required resistors are activated by disconnecting the corresponding “0-ohm

resistor” (see page 76).

Note: The resistance values detected are based on 350-ohm load cells.

For 700-ohm load cells, double the resistance values.
