3.1.5 Meansq
This Subroutine is used to calculate the mean squared current. The
measured current is copied and multiplied with itself using the “smpy16”
routine. The squared current value is then added to the previous squares
to build up a mean value composed of 256 samples.

meansq flow diagram.

3.1.6 Add2tar
Subroutine “add2tar” adds the scaled instantaneous power to the active
tariff buffer and checks whether the value in the active tariff buffer
(48-bit) fits into the 8-digit LCD display. If the result (in decimal) is greater
than 99999999 it is made to rollover to 00000000. If the meter is
recording power delivered to the utility, the display displays
decrementing numbers and a rollover from all zero to all nines is
performed.
