(1)Measuring instrument

Connecting between wiring of home appliance outlet and consumer electronics outlet.
We can measure...
Time of using electric equipment
Instantaneous of electric energy
Cumulative of electric energy etc.

Temperature measurement, by the amount of infrared energy
Range of temperature measurement is -40 to 510 °C

Measure the amount of light flux per unit area of the surface of the irradiated object.
measurement range 0.0～99.9/999/9,990/99,900/999,000 lx

(2)Measuring method

[Measurement of power consumption transition]

1.We integrated electric energy [J] from the numerical value which we had recorded electric power displaying on the Watt Monitor at Continual intervals.
2.We found the timing which you should turn off your consumer electronics where you can use them effectively, by comparing electric power during initial operation and one during prolonging operation.
3.We found that air conditioner is influenced by initial electric power significantly in the course of the experiment, so we measured a plurality of the time changes in the outside air temperature and the room temperature, and calculated specially.

[Measurement of illuminance]

1.We measured the illuminance on the desk on the situation where we use desk light or ceiling lighting with digital luminometer.
2.We found the most efficient way to obtain the necessary illuminance by comparing the measured illuminance and JIS Z 9110-2010.

[Measurement of temperature]

1.We measured the temperature of surface the consumer electronics with radiation thermometer.
2.From measurement result, we identified the consumer electronics which have a great influence on rising room temperature and examined ways to use air conditioners effectively.
