FREQUENTLY ASKED QUESTIONS (FAQ) Regarding Bioelectrical Impedance Analysis If you have any questions about the MA801 relating to scientific basis not addressed in the FAQ, please contact us at the following E-mail address: E-mail: info_cec@charder.com.tw 1. How are Body Composition results measured? Bioelectrical Impedance Analysis (BIA) is a non-invasive measurement of body composition, based on the fact that the human body consists of conductors and non-conductors.
  • Page 67 XII. FREQUENTLY ASKED QUESTIONS (FAQ) ■ Individuals with prosthetics/amputations cannot complete measurements, as BIA requires contact with all 8 electrodes (2 for each hand and 2 for each foot). ■ Individuals with embedded metal may receive inaccurate results, as BIA may interpret highly conductive metal as body water, affecting results.
  • Page 68 XII. FREQUENTLY ASKED QUESTIONS (FAQ) ■ Avoid physical contact with other people or objects during measurement. ■ Avoid talking, and try to hold still as possible during measurement. ■ Perform the measurement in the morning. ■ Perform the measurement under normal temperature conditions (24-28°C). 7.
