1.9.5 Activating security
In order to prevent unauthorized tampering with the
flowmeter’s programming, the XGF868i is equipped with
a security feature that locks all the keys except [ prog ]
(which, when pressed, requires the password).
When the system is locked, access to the menus will
be denied unless the correct password is entered. The
XGF868i is shipped with a default password (2719 and
three spaces). For increased security, the default
password should be changed.
IMPORTANT
Once the system has been locked, it can only be unlocked
by entering the password, because access to the SECUR
submenu is restricted.
While following the programming instructions, refer to the
menu map in Figure 30 on page 42 .
IMPORTANT
It is recommended that all program parameters be
recorded before changing the password. (This information
should be recorded in Appendix B. Data records on page
45 , as a matter of routine.) If the password is lost, the
site data is not retrievable and will have to be re-entered.

6. At the edit password prompt, scroll to

yes to enter a new password.
IMPORTANT

a new password should be entered. If the password is
ever lost, contact the factory for assistance.
7. Enter the new password and press [enter]. Any
combination of letters and numbers up to a total of
7 characters may be used as a password.
8. Verify the new password by entering it again and
press [enter]. Be sure to record the new password in a
safe place.
