The VP-2040 can measure bidirectional four-quadrant active and
reactive energy, and the maximum accumulated value is up to
99,999,999.9
The decimal place will not show. When the accumulated value
reaches to maximum, it will overturn automatically.
The polarity of energy is identical to that of power, both conforming to
the stipulations of IEC standards. For the relevant definitions, please
refer to the descriptions of 4.2 Power Factor Symbols.
The table below describes the interrelationships of various types of
energy and the symbolic relationships between energy and power:
