    VI. INSTRUCTIONS FOR OPERATION Warning Who should not use this device Bioelectrical Impedance Analysis impedance measurements should not be used by subjects with the following characteristics: (1) Electronic medical implants, e.g. cardiac pacemaker A low level imperceptible electrical current will be sent through the body during measurement, which may damage the implanted device or result in malfunction.
  • Page 28 VI. INSTRUCTIONS FOR OPERATION (1) Do not exercise or perform strenuous physical tasks before measurement. Strenuous physical tasks and exercise can result in a temporary change in body composition measurements. As BIA analyzes electrical impedance in the body, activities that might affect impedance (e.g. increased perspiration, dehydration, blood circulation) may affect measurement accuracy.
  • Page 29 VI. INSTRUCTIONS FOR OPERATION (7) Measure height accurately Inaccurate height input will affect estimation of body composition. (8) Perform the measurement in the morning. As a general rule, BIA measurements should be performed in the morning to minimize the influence of activity throughout the day on measurements. The chart above depicts changes in segmental impedance throughout the day, as reported by Oshima et al.

  • Page 41: B.result Sheet Explanation

    Minerals Body minerals are contained primarily inside bone tissue and the bloodstream. Weight The MA801 has a precise built-in scale for weight measurement. During the measurement setup process, users can correct for clothing weight manually. Body Fat Mass Body Fat Mass is calculated by subtracting Fat-Free Mass (FFM) from total body weight.
  • Page 42 VIII.ABOUT RESULTS Muscle-Fat Analysis The length of the black bar indicates the interpretation of the subject's values in comparison with the reference population. If the length of the line falls within the colored area, the subject's values are within normal range. If the length of the line falls to the left or right, then values are below and above normal range.
  • Page 43 BMI cut-off point of 24.9 Accordingly, there are multiple BMI normal range settings available on the MA801 (WHO: 18.5-24.9, Asia: 18-23, Taiwan: 18-24, China: 18-23.9) that can be selected in the System Settings. NOTE: BMI is calculated purely based on height and weight, and does not distinguish between muscle and fat.
  • Page 44 VIII.ABOUT RESULTS Visceral Fat & Subcutaneous Fat Abdominal fat can be further divided into visceral fat and subcutaneous fat. Visceral obesity can occur even if a subject's weight or BMI is within standards. Such subjects are thin on the outside, .
  • Page 45 VIII.ABOUT RESULTS BIVA directly compares the subject’s raw Resistance (R) and Reactance (Xc) values (normalized for height) with a database population of the same age, gender, and ethnicity, identifying how “normal” their results are, minimizing potential inaccuracies that commonly occur for subjects with abnormal hydration.
  • Page 46 The angle of the hypotenuse in the triangle drawn using (Z), (Xc), and (R) is the Phase Angle, which is correlated with factors such as age, gender, malnutrition, inflammation, and BMI. The MA801 compares the subject's phase angle with their respective population. Data-Input GmbH. The BIA compendium.
  • Page 47 , it is recommended for usage in tracking change of an individual subject, rather than a one-time measurement. Charder's patented analysis algorithms can estimate grip strength in context of the overall population after taking into account muscle mass, age, gender, and other factors .
  • Page 48 VIII.ABOUT RESULTS Segmental muscle and fat analysis is important for evaluating progress and identifying imbalance between left-right and upper-lower. The triangle marker indicates if the results for Lean Mass are “Under”, “Normal”, or “Over”. Health Score 72.4 /100 Points The Health Score is calculated through a combination of the various results on the Result Sheet, taking into account variables such as Body Fat, Muscle, Cellular Health, and more.
  • Page 49 VIII.ABOUT RESULTS This section compares the subject's body fat percentage with their respective gender, ethnicity, and age group to place results in context. Edema is defined as excess extracellular water accumulation in the body. The Edema Index is the proportion of ECW and ICW. If the Edema Index exceeds 0.390, it could be a sign of abnormality and a more detailed health check is recommended.
  • Page 50 VIII.ABOUT RESULTS Basal Metabolic Rate Basal Metabolic Rate (BMR) is the minimum required energy to sustain the body's vital functions while at rest. These functions include breathing, blood circulation, regulation of body temperature, cell growth, brain function, and nerve function. BMR tends to decrease with age or reduction in weight, and is positively correlated with increase in muscle.

    XII. 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 69 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 70 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.
