If you are finished or wish to observe the changes you have made on the LCD
panel, press the escape key to return to the Upper Level Mass Flow Screen.
If you prefer to make additional changes, use the left and right arrow keys to move
to other Lower Level Screens.
Note: If you enter a Setpoint that exceeds the full scale value (displayed in the “Full
Scale” screen in the Upper Level), the Smart-Trak 2 will automatically modify this
value to equal the current full scale value. For example, if the current full scale value
of your instrument is 10 slpm and you have entered a setpoint of 15 slpm, the Smart-
Trak 2 will modify your setpoint to 10 slpm when you implement the change. The
Setpoint Value screen will show 10 slpm, not 15 slpm.

at any time, Press Escape—

until you reach the Change Units Screen

Caution!
The Smart-Trak 2 will not
allow you to enter a
setpoint greater than the
current full scale value
set on the instrument.
