Fine Weight Adjustment with ScaleBand

For my next trick, I'm modifying a SECA 800 medical scale with a SECA 220 height bar attachment. The measuring surfaces of the scale and bar will be covered or pegged to a scannable strip that represents the specific axis of measurement. I am going to encode the data of the fine and gross weight adjustments, as well as the height bar, so that the measurements coming off of the bar are unique. That way, the receiving system will not confuse a measurement taken from the fine weight measure with a gross weight or height measure.
