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 E NTERING THE P ASSWORD
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.
