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

access to anyone. After a unique password is assigned, to defeat
the security, the password must be changed back to
TBEAI.
