Power Calibration
1.
The default output settings are V set 220V and F set 50.0Hz.
2.
Connect the output of AFV
+
series U-N, V-N and W-N to a three-phase power
analyzer and a resistive load (it is suggested that the AFV+ output reaches 80%
of the rated power).
3.
Press Output/Reset button at the touch screen to start calibration and the
screen will display the output power value of each phase.
4.
Input the power value displayed on the power analyzer to the U REAL / V REAL /
W REAL.
5.
Press SETTING to perform calibration calculation and the system will generate
new output power value at DISPLAY.
6.
Compare the DISPLAY value and the REAL value; if they are consistent, then the
calibration is completed; if there are differences in one or two phases, it is only
necessary to perform the above calibration again for phases with different
values.
