4.3.3 Password Protection
Before a unique password is assigned, the system assigns TAI by default.
This password will be displayed automatically. The operator just presses the
Enter key to be allowed total access to the instrument's features.
If a password is assigned, then setting the following system parameters can
be done only after the password is entered: alarm setpoints, AUTO-CAL
setup. ZERO/SPAN calibration assigning a new password, range/application
selections, and curve algorithm linearization. (APPLICATION and ALGO-
RITHM are covered in the programming section.) However, the instrument can
still be used for analysis or for initiating a self-test without entering the password.
To defeat security the password must be changed back to TAI.
NOTE: If you use password security, it is advisable to keep a copy of
the password in a separate, safe location.
To install a new password or change a previously installed password, you
must key in and ENTER the old password first. If the default password is in
effect, pressing the ENTER button will enter the default TAI password for you.
Call out MAIN MENU setup by selecting any controls
Use the UP or DOWN key to scroll the blinking over to
Enter to select the password function. Either the default TAI password or AAA
place holders for an existing password will appear on screen depending on
whether or not a password has been previously installed.
The screen prompts you to enter the current password. If you are not using
password protection, press Enter to accept TAI as the default password. If a
password has been previously installed, enter the password using the ENTER
key to scroll through the letters, and the UP or DOWN key to change the
letters to the proper password. The last ENTER enters the password.
In a few seconds, you will be given the opportunity to change this pass-
word or keep it and go on.
