Sample Calculation Based on Diagram 2
Initial resistance in the load cell: 1000 ohms.
- Test weight: 500 kg
- Readout for reference load cell = 498 kg (load cell with the lowest readout
value).
- Readout for load cell being adjusted = 501.1 kg

In this example, note that the test weight (500 kg) is also distributed over the
other load cells, which means that the weight on the load cell being tested is
somewhat lighter. To compensate for this effect, always use the next higher
resistor value.
R = 4.7 ohms
R = 4.7 ohms
R = 4.7 ohms
R = 4.7 ohms
R = 4.7 ohms ((resistor to be installed (see page 42)).
