6.1.1 MAIN METER
The power/energy curve represents the sum of all the contributions from the
energy meters (EM), respectively AC or DC, monitored by the system in the
selected time interval. In building this curve the system only takes into account the
instrument which is identified as “
Main meter
”
If the “
Main meter
” is of virtual type (being the result of the contribution of multiple
real instruments the displayed curve will be built as the sum of all the instruments
whose contribution to the virtual instrument has been enabled.
Note:
if no instrument has been set as “Main meter” and at the same time none
of the installed instruments has been set to contribute to the virtual instrument,
the page “Main meter” will include no chart.
Note: in charts the sampling frequency (for Power and Energy), depends on the
storage interval set on VMU-C. It can be: 5,10,15,30,60 minutes.
