10 Weighing and Force Measurement Practices The basis for all electronic force measurement or weighing is measurement of stress in a loadcell body. To obtain optimal results it is necessary to establish a few basic rules, otherwise the effect may be a nonlinear or non-repeatable response. Read and follow these tips and see the illustrations on the next page. 10.1 Load Centering For accurate performance the force acting on the unit must be in line with the unit.
