7.1.4 Test Mode
Test mode enables you to select which measuring value (active, reactive,
I
2
, U
2
) is output to the optical test output.
In the display, values for active, reactive and apparent energy are
available. Depending on parameter setting, the resolution of the display
register can be increased for faster testing.
