Display password
A password can be used to control access to either the off-line maintenance menu, the alarm menu, or
both. The same code is used for both:
•
If both passwords are enabled, the user must enter the password to access the top-level off-line
menu. The user can then access either the alarm menu or the off-line maintenance menu
without re-entering the password.
•
If only one password is enabled, the user can access the top-level off-line menu, but will be
prompted for the password when he or she attempts to access the alarm menu or the off-line
maintenance menu (depending on which password is enabled). The user can access the other
menu without a password.
•
If neither password is enabled, the user can access all parts of the off-line menu without a
password.
For information about enabling and setting the display password, see Section 8.14.
Note: If the petroleum measurement application is installed on your transmitter, the display password
is always required to start, stop, or reset a totalizer, even if neither password is enabled. If the
petroleum measurement application is not installed, the display password is never required for these
functions, even if one of the passwords is enabled.
