ASSWORD
Security can be established by choosing a 3 digit password (PSWD)
from the standard ASCII character set. (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 an
analysis range.
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 TAI by default. This allows access to
anyone. After a unique password is assigned, to defeat the security, the
password must be changed back to TAI.
If a password is assigned, then setting the following instrument
parameters can be done only after the password is entered: span and
zero settings, alarm setpoints, analysis range definitions, switching
between auto ranging and manual override. In addition, all System
functions such as setting up an auto-cal, self-test and assigning a new
password etc. with the exception of Track/Hold and Model cannot be
accessed without entering a password. However, the instrument can still
be used for analysis without entering the password.
If you have decided not to employ password security, use the
default password TAI. This password will be displayed automatically by
