Changing the display item
You can only select U1, U2, U3, U4, I1, I2, I3, and I4 in the inter-
harmonic time series graph.
SELECT

The display items that can be selected differ depending on
the connection method.
θ indicates the phase difference between the voltage and the
current for that channel.
U1, U2, U3, U4
Voltage (CH1/2/3/4)
I1/I2/I3/I4
Current (CH1/2/3/4)
P1/P2/P3
Active power (CH1/2/3/)
Psum
Total active power
θ1/θ2/θ3
Phase difference (CH1/2/3)
θsum
Total phase difference
Changing the X-axis scale
The Y-axis scale cannot be changed. The maximum value for the
Y-axis is the same as the full-scale range value.
