<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of independently avoiding stop of supply of power when used by being wired to an electrical outlet from a power source via a breaker. <P>SOLUTION: The electronic apparatus (31+32+33) includes a voltage measurement storage means 16. The voltage measurement storage means 16 measures in advance the non-load voltage of a power source output terminal 6 to which electronic apparatus (31+32+33) is connected so that no loads are applied to a power source 3. The means 16 also measures in advance the reference load voltage of the power source output terminal 6 to which electronic apparatus (31+32+33) is connected so that load is applied to only the power source by the heater 76 of the electronic apparatus (31+32+33), which is used as reference load. In addition, the means 16 measures the output voltage of a power source output terminal 6 when the electronic apparatus (31+32+33) is used. The electronic apparatus (31+32+33) further includes a consumption power arithmetic means 17 for calculating the total consumption power of the power source 3 from the load value, non-load voltage, reference load voltage and output voltage of the heater 76. <P>COPYRIGHT: (C)2007,JPO&INPIT |
