Zero line current measurement
Where the current is measured may have some effect on the measurement results. To
mitigate this effect, consider where the voltage and current are measured. For a signal
with high voltage and low current, the voltage channel should be connected to the side
that is closest to the source, the current channel should be connected in series (or the
sensor should be placed) to the side that is closest to the load (as shown in the wiring
diagrams); for a signal with low voltage and high current, connect the voltage channel
to the side that is closest to the load, and connect the current channel in series (or the
sensor should be placed) to the side that is closest to the source. Please refer to the
appendix "Measurement Error Caused by the Channel
Wiring Group
When you select a specific wiring selection, use a combination of 2 or more channels, which is called
a wiring group.
For example, when the wiring selection of channel 1 is set to 3P3W2M, channel 1 and channel 2 form
a wiring group.
Enter the Wiring Selection Configuration:
1. From the Main screen of any view mode select
2. The Configuration interface of wiring selection is as shown in
3P4W3M 3P3W3M
