Infrared Gas Analyzer Operation 4

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.

4.3.3.1Entering the Password

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 PSWD, and press 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.

Enter password:

T A I

or

Enter password:

A A A

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.
