Notes: The "YES/NO" targets are displayed only if they are "YES". The
impedance is dependent upon the CTYP setting. The internal
impedance values are for a 5A ct. The impedance value is multiplied
by 5 if a 1 A ct is used (CTYP = 1). The angles are not displayed if the
magnitude of the value or the reference is less than 0.5 a or 0.7 rms.
