Product code: MNW ## 4. Device Description #### Description of the features The E.S- BC is a single frequency electrical bioimpedance analyzer. The device accurately measures current, voltage and phase angle, and calculates impedance, resistance and reactance. These measurements and calculations are used to estimate the body composition: fat-free mass (FFM) and fat mass (FM), total body water (TWB) and fluid distribution: intracellular water, and extracellular water. It has a tetra-polar set of leads, which are attached to self- adhesive skin electrodes. The E.S- BC has two operating modes: Direct and Algorithm. Direct Mode measures and displays values for impedance (Z), phase (Ph), resistance (R) and reactance (Xc). Algorithm Mode displays estimates of fat-free mass (FFM) ,fat mass (FM), total body Water (TBW), intracellular water (ICW), and extracellular water (ECW), plus their percentages. The device computes these values using accepted peer reviewed published algorithms tailored to the patient type: general population, obese patients, or children. #### 5.
