Digital measuring instrument for displaying a measured value that varies over time

Digital measuring instrument for displaying a measured value (E) varying over time, comprising sequence control means (3) for ascertaining at least one instantaneous value in each of a plurality of measuring cycles by sensing a measured value (E) and for forming a cycle value from the instantaneous values occurring per measuring cycle, said sequence control means (3) including a memory (3b) storing the most recent cycle value until a new cycle value is present that replaces an old cycle, a digital display (1a) connected to said sequence control means for displaying a digital display value derived from the most recent cycle value in response to a control signal, said sequence control means (3) retaining the digital display value until it forms a current digital display value from a new cycle value in response to a new control signal, said sequence control means (3) forming differential values between a given digital display value and the continuously occurring cycle values, an analog differential value scale (7a) connected to said sequence control means for displaying various differential values, and means (4) connected to said sequence control means containing at least one switching element (5) emitting a control signal after the expiration of a predetermined holding time for switching said digital display (1a) to the instantaneous current display value.
