ABSTRACT:
The invention relates to a charging method and a charging arrangement for a measuring system which measures the heart rate. The functional unit of the measuring system comprises at least a transmitter unit (100) and/or a receiver unit. The charging arrangement comprises a charging unit (340). The charging coil (320) of the charging unit is arranged to transfer electric energy inductively to the power source (302) of the functional unit (100) via an induction coil (310). The induction coil (130) of the functional unit (100) used for charging is connectable to more than one inductively active function in addition to charging.
