Wave margins
The wave margins ascertained by the system are marked by red marks. From the difference
between these marks, the main measurement values P, P Q, QRS and QT as well as the
values of QTc derived from them are determined.
Locate the wave margin table of the displayed lead on the upper of the screen. You can
correct the wave margins by moving the marks.
1. Click on the mark and drag it to the desired position.
As soon as you have moved a mark, new values from the changed wave margins are
entered on the bottom line.
2. Click OK to accept the new values.
The manually ascertained values are taken over in the upper line and marked with
MAN. From now on, the system uses only these values.

ascertained values again.
You can toggle between the manually and the automatically ascertained values.
