Note: The average current is calculated in the average time set in the setup.
The average neutral current will be showed only if the insertion type is 4
wires.

Note: The maximum average current is calculated in the average time set in
the setup. The maximum average neutral current will be showed only if the
insertion type is 4 wires.
