Salam, 

This week, I'm start to collect the data for fluorescent tube light for 14 days which is two weeks. I will collect the data for each day at 12a.m. It begin at 12a.m on 31 March until 14 April 2014. The data is collected from multifunctional mini ammeter. Electricity consumption and power cost will collected. However, the tariff is RM0.31 while TNB tariff is RM0.312. Therefore, the discrepancy is RM0.002. 

To ensure the data that I've been collected is reliable, the comparison will be shows in graph after finish the data collected process. The comparison is between TNB tariff and mini ammeter tariff (+discrepancy calculation).

EC is Electricity Consumption while PC is Power Cost. The decimal place is only two for PC. The result for each day will be tabulated.

P/s: Stay Tuned.
