Rossmax Z1 Automatic BP Monitor complies with the European regulations and bears the CE mark. Blood pressure measurements determined with Z1 are equivalent to those obtained by a trained observer using cuff/stethoscope auscultation method, within the limits prescribed by the American National Standard, Electronic or Automated Sphygmomanometers. Real Fuzzy Technology determines ideal cuff pressure based on one's systolic blood pressure and arm size. Users no longer need to pre-set the inflation level before measurement. The technology eliminates arm discomfort through unnecessary high inflation settings and also prevents inaccurate readings caused by erroneous cuff inflation levels. The "Movement Detection" helps reminding the user to remain still and is indicating any body movement during measurement. The specified icon appears once a "body movement" has been detected during and after each measurement. Cuff Detection detects and indicates whether the cuff is wrapped around the arm properly. This blood pressure monitor has passed the criteria of the European Society of Hypertension by achieving all requirements. This monitor further meets the AAMI accuracy standard requirements (AAMI/ANSI/ISO 81060-2).
