DigitalFlow™ GF868 Programming Manual (1-Channel) 35
Chapter 1. Programming Site Data
1.15 Activating Security
In order to prevent unauthorized tampering with the flowmeter’s programming, the Model GF868 is equipped with a
security feature that locks out the following menus:
• Program Menu [PROG]
• Calibration Menu [CAL]
• Log Menu [LOG]
• Clear Menu [CLR]
When the system is locked, access to the above menus will be denied unless the correct password is entered. The Model
GF868 is shipped with a default password, which is given later in this section. 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.
To program the SECUR submenu, press [ twice and [F2] at the initial User Program screen. Refer to Figure 13 on
page 89.
IMPORTANT: It is recommended that all program parameters be recorded before changing the password. (This
information should be recorded in Appendix B, Data Records, as a matter of routine.) If the password is
lost, the site data is not retrievable and will have to be re-entered.
1. At the Lock Out prompt, press [F1] = UNlck to unlock the system and return to the Global PROGRAM prompt, or press
[F2] = LOCK to lock the system.
Note: If the system was unlocked at the above prompt, the following three prompts do not appear.
2. Enter the current Password (2719 is the default password) and press [ENT].
3. At the ?Edit Password prompt, press [F1] = NO to leave the password unchanged and proceed to Procedure Options
on the next page, or press [F2] = YES to enter a new password.
IMPORTANT: Since the default password is printed in this manual, a new password should be entered. If the password is
ever lost, contact the factory for assistance.
4. Enter the New Password and press [ENT]. Any combination of letters and numbers up to a total of 21 characters may
be used as a password.
Note: Keep in mind that the password may have to be entered frequently from the keypad. A long and/or complex
password may soon become annoying to use.
5. Verify the New Password by entering it again and press [ENT]. Be sure to record the new password in a safe place.
