6.15Zeropulsetest
To enable evaluation for the zero pulse test, P541/P571 = ON (1) is set. On the
oscilloscope it can then be depicted with the measurement variables CH1/3_Np. To
make the zero pulse clearly visible, the measurement variable remains high until the
next zero pulse appears. Conversely, the measurement variable remains low until
another zero pulse appears. Bear in mind that the pulse width of the scope signal
does not match the pulse width of the actual zero pulse.
