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

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 pass-

word for you.

Press

mode.
