Zusammenfassung:	The multimeter (10) when not in use stands in a base (20) which is connected to a mains cable (35). The base has a transmitting coil (34) which operates at between 20-60 kHz and is fed from an oscillator (33), a filter/rectifier (32) and a filter (31). The multimeter receives the inductive energy through a receiving coil (41) which supplies the batteries through a filter rectifier (42) under the control of a charge management unit (43)
