flowmeter’s programming, the XGF868i is equipped with
a security feature that locks all the keys except [

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.

by entering the password, because access to the SECUR
submenu is restricted.

recorded before changing the password. (This information
