Abstract
A measuring device provided with an electronic display for displaying a measured value has a main body composed of two members which are rotatable relative to each other. A plurality of switch elements which enable selection of a desired measuring factor are provided on portions of the main body through which the two members rotate relative to each other. The selection of a switch element is effected on the basis of the fact that the switch element stays in a connected state for a predetermined period of time, or by actuating a selector button. The result of measurement is displayed on the electronic display in digital and/or analog form.
