3.3.2 Password Protection
Before a unique password is assigned, the system assigns
TAI
by default.
This password will be displayed automatically. The operator just presses the
Enter key to be allowed total access to the instrument’s features.
If a password is assigned, then setting the following system parameters can
be done only after the password is entered: alarm setpoints, assigning a new
password, range/application selections, and curve algorithm linearization.
(APPLICATION and ALGORITHM are covered in the programming section.)
However, the instrument can still be used for analysis or for initiating a self-test
without entering the password. To defeat security the password must be
changed back to
TAI
.
NOTE: If you use password security, it is advisable to keep a copy of
the password in a separate, safe location.
3.3.2.1 Entering the Password
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
TAI
password for you.
Press
System
to enter the
System
mode.
