When determining the angle, take note of the quadrant of the result. The following table lists the quadrants
and the angle range obtained from the operational signs of the real and imaginary parts of K0 .

+ + + I 0° to 90° arc tan (|Im| / |Re|)
+ - - IV -90° to 0° –arc tan (|Im| / |Re|)
- - + III -90° to -180° arc tan (|Im| / |Re|) –180°
- + - II +90° to +180° –arc tan (|Im| / |Re|) +180°
In this example, the following setting value for the Angle (K0) parameter is obtained:
