Pressing <Enter> will logout the current user and protect the system

If user has LOGGED OUT, then only the following SUB MENU

18. LOGOUT (which only repeats the logout)
19. MODEL
Note however, that the instrument can still be used for analysis
without entering the password. To defeat security the password must be
entered.

The MODEL screen displays the model, and software version
information. It is accessed via the MAIN MENU by scrolling (▲▼> to
MODEL and pressing <Enter>.
4.4.9 System Self-Diagnostic Test
The Model 4030 has a built-in self-diagnostic testing routine.
Preprogramming signals are sent through the power supply, output
board, preamp board and sensor circuit. The return signal is analyzed,
and at the end of the test the status of each function is displayed on the
screen, either as OK or BAD. If any of the functions fail, the System
Alarm is tripped.
Note: The self diagnostics are run automatically by the analyzer
whenever the instrument is turned on, but the test can also
be run by the operator at will.
Note: The self diagnostics will interrupt analysis temporarily.
To initiate a self-test:
<▲▼> From the MAIN MENU scroll to the SELF-TEST
function.
<Enter> Activate the SELF-TEST function by pressing <Enter>.
This brings up the SELF-TEST initialization screen.
