To Center Display at Cursor Location
1. Position cursor at the point where you want to center the plotting area. (For
details about displaying and moving cursor, see “To Display or Move Cursor” on
page 5-8.)
2. Select SCALING primary softkey.
3. (if both Y1 and Y2 axis are set up) Select desired measurement curve by using
AXIS primary softkey.
4. Select CENTER AT CURSOR secondary softkey. The plotting area is centered
around the cursor location.
If no cursor is displayed before step 4, performing step 4 displays a long cursor at
the center of the plotting area.
To return plotting area to original position
Select CANCEL SCALING secondary softkey.
To Draw Line through Two Specified Points
1. Select LINE primary softkey.
2. Set LINE SELECT softkey to 1 or 2. Selecting this softkey toggles the setting.
3. Set LINE secondary softkey to ON. A line and two cursors are displayed.
Selecting LINE secondary softkey toggles as follows:
OFF ® ON ® OFF
The line mode should be normal. So (GRAD MODE, TANGENT MODE, or
REGRESS MODE) softkeys should not be highlighted. If one of these softkeys
is highlighted, turn off by pressing the softkey.
4. Move cursors to desired locations by using arrow keys of the
MARKER/CURSOR key group. To select the cursor you want to move, use the
SELECT CURSOR secondary softkey.
If it seems that only one cursor is displayed, the cursors are at the same location.
When lines are displayed and when ON is set in the LINE PARAMETER field on the
DISPLAY: DISPLAY SETUP screen, their X and Y intercepts and gradients are also
displayed in the plotting area.
