The following steps are necessary to minimize corner load errors:

This aligns the load cells with the displayed value of the reference cell.

Note:

The soldering studs are factory short-circuited for the resistances.

1. Select the load cell with the lowest displayed load as the reference cell.
2. In the junction box, remove the jumper from the relevant measurement

cable () and solder in a resistor according to the abovementioned formula (in
the example 4.38

Ω

).

3. After that, recalibrate the scale.
