    • Easy to use: All primary functions have their own key on the keypad
    • Automatic internal adjustment time-controlled every 2 hours. Guarantees high degree of accuracy and makes the balance independent of its location
    • Capacity display: A bar lights up to show how much of the weighing range is still available
    • USB data interfaces for transferring weighing data to the PC, printer, USB sticks, etc.
    • Draught shield standard on all models with [Max] = 600 g, weighing space WxDxH 145×160×80 mm
    • Weighing surface (d): 80 mm


    Internal adjusting (CAL): Quick setting of the balance's accuracy with internal adjusting weight (motordriven). Data interface RS-232: To connect the balance to a printer, PC or network USB data interface: To connect the balance to a printer, PC or other peripherals. GLP/ISO log: with weight, date and time. Only with KERN printers, see Accessories Piece 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, USA Strain 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, allowing the measured value to be calculated. 3 years warranty
