ABSTRACT:
An electric display device for a vehicle, particularly a motor vehicle, has at least one display instrument, at least one memory which stores a desired display value and can be set with the display instrument in a test phase, as well as switch means for the switchable dividing of pulses of a variable to be displayed, in particular a speed of rotation. In order to be able, during the test phase, to check a division which has been set, the memory stores at least two desired display values. The output of each of the stored desired display values to the display instrument is switchable by the switch, which also effects the switching of the division. In this way, during the test phase, only the desired display value which corresponds to the setting of the switchable division of pulses is shown.
