– In this contents, objects since Android2.1. – The size of the object: The resolution is terminal of "480×800" or "480×854". – Operation verification ending terminal: XPERIA SO-01B, GALAXY S SC-02B, and GALAPAGOS 003SThe application program that checks power consumption appears. The content written in an electric meter is set, and electric meter disk measures the made time by one rotation. "Taskiv-Chan" firmly teaches the method of the setting. The following items are displayed on the result screen. – Electric consumption of target of one month- Expectation electricity consumption of one month- Average power consumption- The remainder to electric power used upper bound- Time necessary for one rotation of disk- Set amperage- Set number of rev/kwhThe electric power demand graph of Tokyo Electric Power Company can be displayed. In addition, yesterday can be compared with today’s data. The procedure of the measurement is as follows. 1.The targeted value of the amount of power consumption of one month is set. 2.Setting of amperage under contract3.Setting of number of rev/kwh(It is written in an electric meter. )4.The stopwatch is started. (When the part where the disk is black is seen, it is started. )5.The stopwatch is stopped. (Please stop it when you see the part where the disk is black. )6.The result is displayed.The average electricity consumption of the ordinary family (Japan) is 290kwh. Let’s set this value to the target, and aim at the power saving mastering.
