9.6.1 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.
The device automatically locks the write-protected parameters again if a key is not pressed for
10 minutes in the navigation and editing view. The device locks the write-protected parameters
automatically after 60 s if the user skips back to the measured value display mode from the
navigation and editing view.
If write access is activated via access code, it can be also be deactivated only via the access
code (

9.6.2 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.
