Abstract: A method for operating a measuring device includes: storing a voltage membership function; assigning a voltage membership degree to a voltage fuzzy set of sufficient buffer voltages; storing an operating parameter membership function; assigning an operating parameter membership degree to an operating parameter fuzzy set of sufficient operating parameter values; determining an operating parameter value and measuring a first buffer voltage at a first time; executing a fuzzy algorithm that involves determining the voltage membership degree of the first buffer voltage using the voltage membership function, determining the operating parameter membership degree of the operating parameter value using the operating parameter membership function, and determining a result membership degree by combining the voltage membership degree and the operating parameter membership degree; and determining a further method step which requires no more than an available energy for a duration of an execution of the method step.

Abstract: A measuring device for measuring a measured variable with a sensor device (2) and an output device, which generates at least one output signal based on at least one sensor signal of the sensor device (2). To provide a measuring device that is flexible in terms of signal output, the output device has at least two signal outlets (4, 5) for outputting of the at least one output signal.
