5 Toggle the Edit Line softkey to select the limit line you want to edit.

6 Turn the Delay knob to move the X-coordinate of the cursor to the

time corresponding to the first point.

If a mask has been previously created, both the X and Y coordinate of the

cursor will track the selected limit line.

Turn the knob closest to the Cursors key to move the

Y-coordinate of the cursor to the voltage corresponding to the

first point.

8 Press the Mark softkey to mark this point as the first point of a line

draw.

9 Turn the delay knob to move the X-coordinate of the cursor to the

time corresponding to the second point.

10 Turn the knob closest to the Cursors key to move the

Y-coordinate of the cursor to the voltage corresponding to the

second point of the line.

11 Press the Connect softkey to draw the line between both points.

12 Repeat procedures 5 through 11 until the desired mask is created.

Mask Editor Operating Hint

When you want to move the cursor to a particular location, it is essential to first

move the X-coordinate of the cursor then the Y-coordinate. Otherwise, the

movement of the Y-coordinate changes the position of a pixel at an undesired

location.

After you press the Connect softkey, the two points are connected by a straight

line. Points between the two end points are interpolated. However, if the

voltage of a particular point during interpolation violates the rule of the voltage

at the maximum limit ≥ the voltage at the minimum limit, the voltage is set to the

same value as the other limit.

After you have marked the first point, pressing the Mark softkey again cancels

the previously marked point and starts the procedure over.

After you have connected the two points, pressing the Connect softkey again

will undo the connect operation.
