Operation

Pressing <Enter> will logout the current user and protect the system from unauthorized changes to parameters.

If user has LOGGED OUT, then only the following SUB MENU procedures may be executed:

17.PASSWORD

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.

4.4.8 The Model Screen

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.
