Write protection via access code

Using the customer-specific access code, the parameters for the measuring device configuration are
write-protected and their values can no longer be changed via local operation.
Define access code
1. Navigating to the "Define access code" parameter: Setup ® Advanced setup ® Def. access
code
2. Define a max. 4-digit numeric code as an access code.
à The -symbol appears in front of all write-protected parameters.
Parameters that can always be changed
The write protection does not include certain parameters that do not affect the measurement. Despite
the defined access code, they can always be modified, even if the other parameters are locked.
Language
If no key is pressed for 10 minutes in the navigation and editing mode, the device automatically
locks the write-protected parameters. If the user goes from the navigation and editing mode back
to the measured value display mode, the device automatically locks the write-protected parameters
after 60 s.
• If write access is activated via access code, it can be also be deactivated only via the access
code (® ä 40).
• In the "Description of Device Parameters" documents, each write-protected parameter is
identified with the
10.8.2

Write protection via lock switch

Unlike write protection via user-specific access code, this allows write access to the entire operating
menu - other than the Contrast display parameter - to be locked.
The values of the parameters are still visible, but can no longer be changed (except for Contrast
display), either via the local display, the service interface (CDI) or HART protocol.
