This page shows measured and calculated energy values. Page is activated by key F1 of Load
Values screen.
Active, reactive and apparent energies are accumulated beside the measurement and shown on this
page. Accumulation of these energies can be stopped and started again (key F3) or just restarted by
F4 key.

Online energy accumulation - Sum of Energies (resp. Powers) accumulate values from the beginning
automatically. With F3 button it is possible to suspend/resume accumulation.
When Dial test screen is accessed these registers will be cleared but only if Test Initialization has
