The two buttons "O Vert A" or "O Vert B" activate vertical cursors and place them on
TRACE A or TRACE B. Both the cursor and its label fields are displayed in the color of
the associated trace.
Activating the "O Vert A-B" button displays a gray cursor which represents the differ-
ence between the values for TRACE A and TRACE B.
The two buttons "O Hor A" or "O Hor B" activate horizontal cursors and place them on
TRACE A or TRACE B. Both the cursor and its label fields are displayed in the color of
the associated trace.
The "Movement" button leads to the next softkey level where you define how the cur-
sor can be moved. The second line of the label shows the currently set step size in
parentheses.
Moving the Cursor
Only one cursor is active and can be moved in the graph at any one time. The active
cursor is displayed with a solid line; the inactive cursor is displayed with a broken line.
The "O<->X" button alternately switches the O and X cursor. Alternatively, the Enter
key or a rotary-knob click can also be used to toggle between the two cursors.
In the case of operation using the mouse, the desired cursor or one of its display fields
can be activated and moved by simply clicking with the mouse.
A cursor can be moved in a number of different ways:
●
The active cursor is linked to the rotary knob and can be moved directly using the
rotary knob.
●
On the external PC keyboard, the keys TAB / CTRL + TAB move the cursor to the
right / left.
●
In the case of operation using the mouse, the cursor can be clicked and moved by
holding down the mouse key.
The step size with which a cursor is moved can be set using softkeys. To do so, the
softkey of the desired O or X-cursor must first be selected:
The "Movement" button opens the next softkey level where various step sizes for mov-
ing the cursor are offered irrespective of the graph currently being used. This is descri-
bed in greater detail below. The currently selected step size is indicated in brackets in
the second label line of the "Movement" button.

"Next Pixel "
Selecting the "Next Pixel" button moves the cursor by one pixel in the graphic with
every increment. If there is not a measured value at every pixel in the graphical dis-
play (because only a few measurement points were recorded relative to the size of
the displayed graph), the cursor value is interpolated linearly at the pixels between
