Synchronization of mean active
power:
15 - 15 minutes’ walking window
(record synchronized with the clock
every 15 minutes)
c_15 – measurement synchronize
with the clock every 15 minutes.
c_30 – measurement synchronized
with the clock every 30 minutes,
c_60 – measurement synchronized
with the clock every 60 minutes,

tHd – THD
ALL – successive calculations of
harmonics inserted in registers

( in this mode, the active energy is
calculated)
