8.3.8 User roles and related access authorization
The two user roles "Operator" and "Maintenance" have different write access to the parameters if
the customer defines a user-specific access code. This protects the device configuration via the local
display from unauthorized access (

1) Despite the defined access code, certain parameters can always be modified and thus are excepted from the write
protection, as they do not affect the measurement. Refer to the "Write protection via lock switch" chapter
For detailed information about parameters which can always be modified, refer to the Operating

parameters are now re-enabled.
8.3.10 Enabling and disabling the keypad lock
The keypad lock allows you disable access to the entire operating menu via local operation. Thus
navigating through the operating menu or modifying the values of individual parameters is no longer
possible. Only the measured values on the measured value display can be read off.
The keypad lock is enabled and disabled in the same way:
The user is in the measured value display.
