Every day between 11:00 am and 12:00 pm, U-Scan will automatically purge its fluid collection tube (used to collect your urine sample) by blowing air into the tube. 

This process is meant to remove any incidental fluid that is remaining inside the collection tube to ensure that the next measurement is as accurate as possible and to avoid any buildup of humidity within the device. You will hear mechanical whirring noises coming from the U-Scan while it purges. 

The U-Scan also syncs all currently stored measurement data during the daily purge process. 

Along with daily cleaning and upkeep, this automatic daily process will ensure U-Scan functions properly.
