have to press the keys in the following combination ( Escape - Enter - Escape ) to unlock the meter with a “Valid
Passcode”. The entered “Passcode” is validated and the user is allowed to access the menu based on
privileges. The meter will go back to Full-Lock mode if no keypad activity is noted for a “Determined Time”.
• Display Locked – This level can be achieved by entering a “Valid Passcode” assigned for this role. In this
Mode/Level, the User has privilege only to view data. The User will be allowed to select the diaplay parameters.
Any other changeable parameter is denied access.
• User-1 / User-2 / User-3 / User-4 – The User has to enter a “Valid Passcode” to have access to the menu
attached to this role. The User with this role will have rights of Display Locked mode and some predetermined
“write privilege” with which he may modify parameters (attached to this role).
• User Admin – This User will have “Administrator privilege” in addition to privileges of Lower level. This user is
given the rights to change the “Passcode” for all user-levels. (This does not include Full Lock and Display
Locked). The Administrator has the privilege to modify the timeout value, which is used to determine the time
taken to switch back to Full Lock mode (if no keypad activity is noted). The “Administrator privilege” does not
include access to Service or Factory Menu. The Administrator has no rights or control on
Service/Factory/Engineering Levels or their “Passcodes”.
• Field Service – This User has access to the “Service Menu” in addition to “Administrator privilege”. It is not
accessible by User Admin.
• Factory – This User has access to “Factory privilege” in addition to “Service privileges”. It is not accessible by
User Admin.
• Engineering – This User is the only user with Full access to the meter. Only this user has rights to change the
“Passcodes” for Factory and Service. It is not accessible by User Admin.
