Herein, when advancing the input device (10), said change amount is adapted from a fine-tuning-state value to a tuning-state value larger than the fine-tuning-state value in case a first condition is met. In this way a method for setting an operational parameter in a medical device is provided which allows for an easy and comfortable adjustment of an operational parameter for programming the medical device, for example in the context of an infusion operation. ## Claims ### Claim 1 A method for setting an operational parameter in a medical device, comprising: actuating an input device to set an operational parameter displayed on a display device of the medical device, wherein the input device is advanceable in an actuation direction by movement steps to increase or decrease the operational parameter by a change amount associated with one of the movement steps and wherein the operational parameter is adjustable over a predefined overall numeric range with at least a first predefined numeric sub-range within the predefined overall numeric range and a second predefined numeric sub-range within the predefined overall numeric range, wherein each sub-range is associated with different predefined change amounts for a fine-tuning-state numeric value and a tuning-state numeric value by which the operational parameter is adjusted when in the respective state, and adapting, when advancing the input device within a subrange, said change amount from the fine-tuning-state numeric value to the tuning-state numeric value larger than the fine-tuning-state numeric value in case a first condition is met, wherein adapting said change amount in dependence of the advancing of the input device comprises applying a first set of values with the operational parameter in the first
