(See Installing or Changing a Password, below, for a table of
ASCII characters available.) Once a unique password is
assigned and activated, the operator MUST enter the
UNIQUE password to gain access to set-up functions which
alter the instrument's operation, such as setting the instrument
span or zero setting, adjusting the alarm setpoints, or defining
analysis ranges.
After a password is assigned, the operator must log out to
activate it. Until then, anyone can continue to operate the
instrument without entering the new password.
Only one password can be defined. Before a unique
password is assigned, the system assigns TETAI by default.

assigned, to defeat the security, the password must be
changed back to TETAI.
