PIPETTE DEVICE WITH FUNCTIONAL TEST AND METHOD FOR PERFORMING A FUNCTIONAL TEST FOR A PIPETTE DEVICE

摘要

The invention relates to methods and pipetting devices for detecting at least one power state of the pipetting suction mechanism of a pipetting device. Such a method and such a pipetting device each uses an electrical control device, an intake mechanism comprising, inter alia, an electrically driven motor, a measuring device having a pressure sensor or a motor current detection for characterizing the physical work performed by the suction mechanism, wherein the pipetting device may be partially provided with a resistance means by means of which during the implementation of the method, the mechanical, in particular the hydraulic resistance of the suction mechanism against the performed by the engine physical work is increased, wherein the control means is adapted to detect a power state of the pipetting device to at least one value to detect this measured variable as a function of a defined movement of the piston element, to store the at least one value of this measured variable in the data storage device.
