Hand-held pipetting device

A computer program code for providing an input screen page on the screen of a hand-held pipetting device used for pipetting at least one liquid sample and comprising a connecting section for connecting at least one pipetting container, an electrically controlled moving member for aspirating the at least one sample into the at least one pipetting container, for holding the sample in the at least one pipetting container, and for dispensing sample from the at least one pipetting container when performing a pipetting operation, and a touch-sensitive screen for inputting the parameter values of user-definable pipetting parameters, wherein a parameter set of pipetting parameters completely defines the pipe tting operation, and wherein the pipetting device comprises an electrical control device with a data processing device which is programmed to control the moving member as a function of the at least one pipetting parameter, and at least one actuating element which can be actuated by a finger pressure of a user and whose actuation starts the pipetting operation defined according to the parameter set,

• wherein the program code, when executed by the data processing device of the hand-held pipetting device, results in
• a) a screen page for displaying the pipetting parameters of a parameter set of pipetting parameters is displayed in the screen,
• b) the screen page includes at least one first input tile that displays the value of at least one first pipetting parameter of a base parameter set that defines a base pipetting operation, and touching the input tile opens an input interface that allows the user to enter the value of the at least one first pipetting parameter
• c) the screen page comprises at least one input field, the touching of which enables the selection of at least one second pipetting parameter by the user, the data processing device being programmed, after detection of this user-activated selection, to cause the at least one second pipetting parameter to be added to the at least one first pipetting parameter of the base parameter set to form with said at least one first pipetting parameter the pipetting parameters of a user parameter set defining a user defined pipetting operation, and displaying said selection of said at least one second pipetting parameter to the user in the screen page;
• wherein after completion of the selection, the selection list is closed and the screen page is displayed again and now also displays, in addition to the at least one first input tile, at least one second input tile which displays the selected second pipetting parameter or a value thereof, and touching the at least one second input tile opens an input interface which allows the user to enter the value of the at least one second pipetting parameter.
