    71M6534H Demo Board User’s Manual FORMULAE FOR FAST CALIBRATION A method for non-trigonometric derivation of the factors for the fast calibration is shown below. The phase angle φ is calculated as follows: − VARh ϕ measured measured − VARh measured The value for tan(φ) can be used directly without calculating trigonometric values when...
  • Page 85 71M6534H Demo Board User’s Manual For the current calibration we have to realize that the meter's sig nal is the vector sum of the real (Wh) and imaginary (VARh) parts of the energy. i_gain, the current gain, must be scaled to eliminate power errors and rotated in the complex plane to eliminate phase error.
