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 Ente r 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.
