— devices with this function are able to automatically turn off if the user has not performed any actions for a certain time after the last measurement. This saves battery power, eliminates the need to turn off the power manually, and can be a good insurance in case of forgetfulness. The shutdown time is usually from several tens of seconds to several minutes; in some models, it can be set at your discretion.
