Any function can be selected at any time by pressing the appropriate button (unless
password restrictions apply).
Password Protection
If a password is assigned, then setting the following system parameters can be done only
after the password is entered: span and zero settings, alarm setpoints, analysis range definitions,
switching between autoranging and manual override, setting up an auto-cal, and assigning a new
password. However, the instrument can still be used for analysis or for initiating a self-test
without entering the password.
If you have decided not to employ password security, use the default password TETAI. This
password will be displayed automatically by the microprocessor. The operator just presses the
Enter key to be allowed total access to the instrument’s features.
Note: If you use password security, it is advisable to keep a copy of the password in a
separate, safe location.
Entering 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 TETAI password for you.
