Data Sheet
ENERGIES SCALING
The ADE7763 provides measurements of active and apparent
energies. These measurements do not have the same scaling and
therefore cannot be compared directly to each other.

CALIBRATING AN ENERGY METER
The ADE7763 provides gain and offset compensation for active
and apparent energy calibration. Its phase compensation corrects
phase error in active and apparent energy. If a shunt is used,
offset and phase calibration may not be required. A reference
meter or an accurate source can be used to calibrate

energy measurement in the ADE7763. If a reference meter is
used to calibrate the VA, then additional code must be written
in a microprocessor to produce a pulsed output for this
quantity. Otherwise, VA calibration requires an accurate source.
The ADE7763 provides a line cycle accumulation mode for
calibration using an accurate source. In this method, the active
energy accumulation rate is adjusted to produce a desired CF
frequency. The benefit of using this mode is that the effect of the
ripple noise on the active energy is eliminated. Up to 65,535 half
line cycles can be accumulated, therefore providing a stable
energy value to average. The accumulation time is calculated
from the line cycle period, measured by the period register, and
the number of half line cycles in the accumulation, fixed by the
LINECYC register.
Current and voltage rms offset calibration removes apparent
energy offset. A gain calibration is also provided for apparent
energy. Figure 70 shows an optimized calibration flow for active
energy, rms, and apparent energy.
Active and apparent energy gain calibrations can take place
concurrently, with a read of the accumulated apparent energy
register following that of the accumulated active energy register.

When using a reference meter, the ADE7763 calibration output
frequency, CF, is adjusted to match the frequency output of the
