Fig. 11. Measurement of 15 minutes’ mean active power synchronized
with the clock.
The archive is organized in the shape of a circular buffer. After writing
the 9000 th value, the next overwrites the oldest with number 0, and the
successive, the next with number 1, etc.
If the value of the register 1000 is higher than 1001, that means that the
buffer was overflowed one time at least. Eg, the value 15 in the register
1000, and 14 in the register 1001 means, that there were already more
than nine thousand samples and oldest samples are from the record 15
up to 9000, next from the record 1 to the youngest record with number 14.
The change of the current or voltage ratio, kind of mean power, causes
the archive erasing.
The reset of averaged power or the change of averaging time does not
erase the archive.
The automatic erasing of the archive and averaged power is performed
when changing the voltage or current ratio.
