Lower Level Screens (Changing Parameters)
Getting to the Lower Level Screens:
Your instrument is password protected so that unauthorized personnel will be
unable to change the operating parameters of Smart-Trak 2. To enter the Lower
Level Screens at any time you must first supply the correct password.
Password Screen:
By pressing the “enter” key from any of the Upper Level
Screens you will come to the Password Screen. (If you do not know if you are in an
Upper Level Screen, press escape and you always automatically go to the Mass
Flow Screen in the Upper Level) The display will show:
Enter Password
0000
The first digit will blink. At this point, you must enter the correct password to gain
access to the Lower Level Screens.

If the instrument is being operated for the first time or if no password has ever
been set on the instrument:
You can use the factory default password. The factory
default password is “0000.” To proceed to the Lower Level Screens by using the
factory default password, simply press the “enter” key a second time. If you want
rapid access to permit regular changes to your instrument and you do not desire a
password, this is the fastest way to enter the lower level.

If You Have a Password
:
If you have already set a password, enter it now. To
enter the password, push the up arrow to increase the blinking digit or the down
arrow to decrease the blinking digit. To move to the next digit, press the left or
right arrow and repeat the process. When you have selected your four digit
password, press the enter key.

If You Want to Set a New Password
:
If you want to change the password, you
must first get to the Lower Level Screens. Proceed by entering your known
password or if no password has ever been set on the instrument, us the factory
default password. Follow the instructions in the “Change Password Screen” section
found later in this chapter.
If the password you have entered is correct, you will enter the Lower Level at the
Change Setpoint Value Screen.
