Computer-implemented method for providing access control to a function of an analyzer is presented. A user's log-in data is received from a first data entry terminal. Information descriptive of a position of the first data entry terminal is obtained. It is determined whether the position of the first data entry terminal is within a physical operating (PO) area of the analyzer. A user activatable position sensitive (PS) GUI element is displayed on the first data entry terminal if the position of the first data entry terminal is determined to be within the PO area. The activatable PS GUI element triggers, upon activation, the execution of the function. The execution of the function comprises the execution of a physical action by the analyzer. The display of the user activatable PS GUI element is otherwise prohibited or a non-activatable PS GUI element indicative of the function is displayed.
