Abstract: In order to display a measured value, a digital measuring instrument is provided with a digital display and an analog display. The display value emitted by the digital display is fixed during a predetermined holding time.

The current measured value may be read off at the beginning of a new holding time on the digital display, or it can be ascertained as the sum of the values of the digital and analog displays.
