MEASUREMENT ACCURACY
The measurements are all calculated with fiducial error except for
frequency and THD.
Fiducial error is calculated as follows:
Where Umea means the measured data of one measurement
parameter, and Ureal means the real/actual data of the parameter,
UFV means the fiducial value of this measurement parameter, which
can be defined as Table 15.
For the above mentioned parameters, the measurement accuracy
requirement is 0.5% maximum.
For frequency, temperature, THD+N:
Parameter Accuracy
Frequency: 0.01Hz
Temperature: 1 °C
Accuracy of all orders of harmonics: 5% relative error
Harmonic component% =
Where
means the measuring value of the h
th harmonic voltage/
current;
means the given or actual value of the h
th harmonic voltage/
current.

Note 1:
All registers are of 16-bit. For cases when the current or active/reactive/apparent power goes beyond the above range, it is suggested to be handled by MCU in
application. For example, register value can be calibrated to 1/2 of the actual value during calibration, then multiply 2 in application.
Note 2:
Phase angle is obtained when voltage/current crosses zero at the sampling frequency of 256kHz.
