will appear on the left side of the data plot. If both markers are visible, the differential “Marker B
minus Marker A” value will be displayed at the bottom left of the screen.
The selected marker is represented as highlighted, dashed line; marker’s readout is also
highlighted. Only one marker at a time can be selected. If only one of the markers is visible, it will
be always selected.
