1. A method for calibrating an apparatus for determining body impedance having first and second electrodes being suitable for being electrically coupled to the body, comprising:

  • determining a first period of oscillation for the apparatus associated with an open circuit condition between the electrodes; and

    determining a second period of oscillation for the apparatus associated with a short-circuit condition between the electrodes;

    wherein, the first period of oscillation is indicative of a first calibration value, and the second period of oscillation in combination with a slope coefficient is indicative of a second calibration value.
