Abstract:
1. A circuit for a measuring instrument, comprising: a logic circuit having a digital memory configured for the input and output of measuring signals; a controllable current sink configured to operate a current loop having a limited current range, wherein the controllable current sink is configured to convert information supplied by the logic circuit into an output current on the current loop; an application-specific integrated circuit configured to detect a measurement-specific movement which is connected to the logic circuit for the output of measuring signals corresponding to measuring values of movement; and an energy storage unit connected to the controllable current sink for energy input and connected to the application-specific integrated circuit for energy output; wherein the logic circuit controls the state of connection of the energy storage unit so that the energy storage unit is connected to the application-specific integrated circuit each time the energy storage unit has reached an amount of energy missing in the energy supply of the application-specific integrated circuit.
