4.
Change the magnitude and angle of three phase voltages to achieve the impedances at test points
P1, P2,...., P28.
5.
For test points P1 to P14, observe the operation value for the signal ZOUT and compare the
operation value with the set value.
6.
For test points P15 to P28, observe the operation value for the signal ZIN and compare the
operation value with the set value.
