Zusammenfassung:The invention relates to an apparatus for testing a weighing system of a blood treatment device, in particular a dialysis machine, wherein the weighing system has at least one weighing cell. The apparatus comprises at least one plunger, at least one coil having at least one cavity, in which the plunger is movably accommodated, and at least one current source that energizes the coil, at least at times. The coil or the plunger are arranged on the weighing system in order to apply a defined force to the weighing cell whenever current flows through the coil. The invention further relates to a blood treatment device having such an apparatus, and to a method for testing a weighing system of a blood treatment device.
