Resistor determination:
1. Apply the test load as directly as possible above each load cell and note the displayed value.
2. Starting from the smallest displayed value, the resistance values for the other load cells must be
calculated using the following formula:
R=R
R=R
R=R

3. Replace the jumper of the relevant load cell by the appropriate resistor.
4. Re-calibrate the scale.

After delivery, the jumpers are fitted (the box is prepared for 4-wire connection). The load cell cable must not be
shortened.

When using the cable junction box for load cells in 6-wire connection, jumpers J1 and J2 across blocks Sense
and Supply must be removed (see circuit board photograph).
