User should input Hexa code to set C4.   
User should input “weight unit”, “external resolution”, “display unit”, and “tare”. 
For example, if you want to set “kg (0)” as the weight unit, “low (00)” as the external 

resolution, or “(0)” as TARE you may input “00” as Hexa value. 

User can set 2,000~2,500 for low external resolution or 4,000~5,000 for high external 

resolution.
