Claims21
A measurement device configured to perform physiological measurements of a user body using a direct excitation source, referred to as a DC measurement, or using an alternative excitation source, referred to as an AC measurement, the measurement device comprising:
- a pair of electrodes comprising a left electrode and a right electrode configured to be respectively in contact with the left foot and the right foot of the user;
- a measurement plate configured to receive the user and on which the pair of electrodes is placed;
- a DC measurement circuit comprising a direct excitation source configured to apply a direct voltage or current to the left electrode or the right electrode;
- an AC measurement circuit comprising an alternative excitation source configured to apply an alternative voltage or current to the left electrode and/or the right electrode;
- a discharging circuit, configured to be connected to at least one of the left electrode and right electrode, and
- a commutator configured to selectively connect at least one of the left electrode and the right electrode to:
- the discharging circuit in a set of discharging positions;
- and
- the DC measurement circuit in a set of DC positions, wherein the measurement device is configured to:
