JC series dual counting scale user’s guide 

- 5- 

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.
