a reduced resolution should be selected in the remote scale technical set up. For
example, if a system uses four 2mV/V 1000kg load cells for a scale of 1000kg capacity
then the span output at full scale will be only 2.5mV.
In this situation the resolution should be reduced to give a good number of ADC counts
per displayed division, for example, set to 1:5000 or 1000kg x 0.2kg.
Setting a high resolution without providing a good input to the remote scale ADC will
not give better accuracy and may make the scale difficult to meet performance
specification.
For best performance ensure a minimum of 0.1uV/d.
