How do I Measure the Voltage Phase Difference Between Input Elements on the PZ4000?

It is possible to measure the phase difference by using the function φU1(1)-U2(1) in Hamonics Measurement Mode.
In this mode, if the wiring pattern is set to 1P2W, the PZ4000 will display no value (----).
It is necessary to set the wiring pattern to 3P3W for the PZ4000 to display the measured value for φU1(1)-U2(1).
The phase difference is also available in the Vector display of the Hamonics Measurement Mode.
