We thank Drinhaus et al. for explaining their results. Further data from our measurement series showed the same trend for the model Carestation 650, software version 01 SP 08 manufactured by GE: power consumption in standby mode 56.8±2.3 and switched off 10.7±0/.7 [w] (mean±standard deviation, n=2900 measurement points). The machine was operational without incurring higher power consumption after 51±0.6 [s]. A complete disconnection of the devices from the electrical grid cannot (yet?) be recommended, in our opinion. Machine specific data are lacking in this context, such as for example the power balance after discharge of the internal batteries. Furthermore, in case of a complete disconnection from the grid, semi-automatic switching on/off processes are no longer available—such as “auto on” (Perseus A500, Dräger).
