Only with KERN printers, see AccessoriesPiece counting: Reference quantities selectable. Display can be switched from piece to weight.Recipe level A: Separate memory for the weight of the tare container and the recipe ingredients (net total).Percentage determination: Displays the deviation from the reference weight (100%) in % instead of grams.Weighing units: Can be switched to e.g. nonmetric units at the touch of a key. See balance model.Universal mains adapter: with universal input and optional input socket adapters for EU, GB, USAStrain gauge: An electrical resistor strip that is glued to an elastic deforming body made of aluminium. As the strain gauge is mechanically deformed its resistance value changes, allowingVerification possible. The time required for verification is specified in the pictogram.
