Abstract: Described is a process measurement device having an interface for connecting a plug-in memory, in which a processing measurement device includes a memory operating device that can switch the process measurement device into a memory access mode when the memory is connected to the process measurement device. Also described is a power supply that ensures that the energy demand required for read access or write access to the process measurement device is automatically covered after the connection of the memory by increasing the amount of electrical energy that is freely available in the process measurement device. Undesired undersupply of the process measurement device can thereby be effectively avoided.
