Claim 6:
7. A measurement method (1) for measuring a preload of a frameless door windowpane (2) of a vehicle (3), comprising the following steps:
affixing the measuring device (1) to a frameless door windowpane (2) of a pivotable vehicle door (27) to be tested;
using the measuring device (1) to start recording spatial acceleration data;
opening the pivotable vehicle door (27) to which the door windowpane (2) to be checked belongs along a trajectory (26) from a closed state to an open state;
terminating the recording of spatial acceleration data by the measuring device (1);
using the communications interface (9) to output the recorded acceleration data (6, 7, 8) for a readout;
measuring a pure pivoting movement of the vehicle door (27) that has the frameless door windowpane (2) to be tested; and
subtracting the pure pivoting movement of the vehicle door (27) from the measured movement of the frameless door windowpane (2) to calculate the preload.
