10 Explanations of Power Proportional Distribution
10 - 2 Count Accuracy
10 - 2 - 2The way to reduce errors
CAUTION
When management staff checks the watts in the procedure mentioned below, they would find the calculation to be incorrect due to an incomplete cycle.
Example:
(1) May/24th, read wattmeter and records the watts at 10:00 am
(2) June/24th, read wattmeter and records the watts at 10:00 am
(3) When the count in a period of may/24th to June/23rd is printed out, the total value doesn’t meet the value detected mentioned above on (2) - (1).
iPU stores the information collected in a period of 0:00 am through 23:59 pm as one day information as shown above.
It results in the fact that there are ten hours gaps between on the first day of the counting and on the last day of the count in the above mentioned
column of “Result of detection by management staff” and “Count result”.
As shown in the figure above, this error increases in the season from the intermediate forwarding to the season in which airconditioning is highly
required.
For more accuracy, it is nessary to compare with the value detected at 0:00 am.
