The DMS-30LCDA-4/20S’s span and offset circuitry are optimized to display standard, unipolar readings where a 4mA input always reads “000” and a 20mA input always displays a higher positive number. As shipped, the DMS-30LCDA-4/20S is calibrated to read “000” for a 4mA input and “1800” for a 20mA input.
