6.2.6 Security and permissions
Access levels
The vortex flowmeter features a multi-level security concept, which helps to prevent accidental
or unauthorised configuration changes.
To gain a specific access level you need to log into the device by entering a four digit hexadecimal
password associated with that access level (refer to menu "C6.2 Security"). You are able to
change the passwords of "Operator" and "Expert" access levels if that particular level has been
reached.
The "User" access level does not have a specific password – if you enter any password not
assigned to a level, e.g. "0000" (which is an invalid password), you will fall back to "User" access
level.
The table below lists the access levels, their default passwords and associated permissions.

Table 6-7: Access levels
INFORMATION!
When a particular access level has been enabled, please pay close attention to a "lock" symbol
which might be present at the right side of a menu entry. This lock symbol indicates that your
current access level allows you to read but not write this entry.
INFORMATION!
When entering the four digit password please be sure to type in all leading zeroes – i.e. enter the
default "Operator" password as "0009" and not only "9" by skipping the remaining digits.
INFORMATION!
After a cold start of the device the user role will always be reset to "User".
