6.1 Energy Values
General The energy values are stored in energy registers. The different energy registers
can be divided into:
• Registers containing active energy.
The energy values can be read directly on the display by using the button on the
meter.
Presentation of
register values In direct connected meters the energy is usually displayed with a fixed unit and
number of decimals (normally kWh, with no decimals).
In case the energy is displayed with fixed units and number of decimals the energy
will “roll over” to zeros when the energy is increment ed if all nines are displayed.
The meter can however contain more digits internally, which can be read out via
communication if the meter is equipped with a communication interface.
