A pipette operating device with a functional test and a method for performing a functional test on the pipette operating device

摘要

The present invention relates to a method for recognizing at least one output state of a suction mechanism of a pipette operating device and a pipette operating device used for pipette operation. This type of method and this type of pipette manipulator are pressure sensors for characterizing the physical work performed by electrical controls, especially suction mechanisms with electrically driven motors, and suction mechanisms. The pipette operating device can partially have a resistance device, or by utilizing a measuring device that detects the motor current, the physical performed by the motor while performing the method by the resistance device. The mechanical, especially hydraulic resistance of the suction mechanism to the work is increased and the controller adjusts at least one value of this measurement according to the defined movement of the piston member in order to recognize the output state of the pipette operating device. It is arranged to detect and store at least one value of this measurement in the data memory device. [Selection diagram] FIG. 2b
