![GLP/ISO log: with weight, date and time. Only with KERN printers, see Accessories GLP/ISO log](https://copens-sci.com/media/2022/04/pictos-pc-glp-printer.png)
![Piece counting: Reference quantities selectable. Display can be switched from piece to weight. Piece counting](https://copens-sci.com/media/2022/04/pictos-pcs.png)
![Recipe level A: Separate memory for the weight of the tare container and the recipe ingredients (net total). Recipe level A](https://copens-sci.com/media/2022/04/pictos-rez-a.png)
![Percentage determination: Displays the deviation from the reference weight (100%) in % instead of grams. Percentage determination](https://copens-sci.com/media/2022/04/pictos-percentage.png)
![Weighing units: Can be switched to e.g. nonmetric units at the touch of a key. See balance model. Weighing units](https://copens-sci.com/media/2022/04/pictos-unit.png)
![Vibration-free weighing: (Animal weighing program) Vibrations are filtered out so that a stable weight is obtained. Vibration-free weighing](https://copens-sci.com/media/2022/04/pictos-average-animal.png)
![Suspended weighing: load support with hook on the underside of the balance. Suspended weighing](https://copens-sci.com/media/2022/04/pictos-underfloor.png)
