• DIRECT MARKER/CURSOR softkey
Select DIRECT MARKER/CURSOR secondary softkey to display secondary
softkeys for positioning the marker and cursor. A pointer appears in the CURSOR
and MARKER coordinate fields. These fields are displayed only if cursor and
marker are displayed in the plotting area.
You can move the pointer to the desired field by using the left arrow, upper
arrow, right arrow and down arrow MARKER/CURSOR keys. To move marker
and cursors to desired position, enter coordinate values into corresponding fields
as follows:
• Enter the value by using numeric keys.
• Change the value by rotating rotary knob.
Select CANCEL primary softkey to move marker and cursor back to original
position, and exit the direct marker and cursor function. Select EXIT primary
softkey to exit the direct marker and cursor function.
The marker can move on the measurement curve only, so changing the X value
automatically changes the Y value, and vice versa. If the interpolation mode is
off, the marker moves to the measurement point that is closest to the specified
coordinate.
If the pointer is in a MARKER coordinate field, the following softkeys appear:
• Select MIN/MAX secondary softkey to move marker to minimum
measurement value. If marker is at minimum value, marker moves to
maximum value.
• Select INTERPOLATE secondary softkey to toggle the interpolation mode
on or off. The present mode is displayed on the INTERPOLATE softkey.
• Select SEARCH MORE secondary softkey to move marker to the next
candidate (when more than one measurement point satisfies the specified
value).
• Select MARKER SKIP secondary softkey to move the marker to the next
measurement curve that was added by VAR2 variable or append
measurement.
If the pointer is in a CURSOR coordinate field, the following softkey appears:
• Select MIN/MAX secondary softkey to move cursor to minimum axis point.
If cursor is at minimum point, cursor moves to maximum point.
