The Trigger affects data recording even if you are not viewing the Graph. If you
have set up two or more triggers on separate Graph pages,

data recording will

start when the most recently set trigger condition is met.

Trigger Settings

When the Trigger is turned on, you can open the Trigger Set-

tings dialog box by pressing the left arrow key (you can also select it from the
Tools menu). In the dialog box, use the arrow keys to highlight Trigger Enabled
and press

to enable or disable the Trigger. To change the edge from rising to

falling, or vice-versa, use the arrow keys to highlight Trigger Edge and press

. To set the level, use the arrow keys to highlight Trigger Level, press

enter the desired value on the keypad, and press

again.

You can also turn on the Stop Condition, which causes data collection to auto-
matically stop at a specified time. To turn on the Stop Condition in the Trigger
Settings dialog box, use the arrow keys to highlight Stop Condition and press

. When the Stop Condition is on, an icon (

) and vertical dashed line

appear on the Graph indicating the stop time. While viewing the Graph, hold
down

and press the left and right arrow keys to adjust the stop time. For the

Stop Condition to work, the Trigger must be turned on (but does need to be
enabled).

When you have finished changing the settings in the Trigger Settings dialog box,
press

to accept the changes, or press

to cancel them.

again. The area enclosed by the rectangle enlarges to fill the

screen.

If you have a mouse, you do not have to open the Tools menu to zoom.

Just hold down

while you click and drag on the Graph to draw the rectangle.
