4.3.3 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.
4.3.3.1
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 pass-
word for you.
