Protecting settings from unauthorized access
The following options exist for protecting the configuration of the measuring device from
unintentional modification after commissioning:
• Write protection via access code (
• Write protection via lock switch (
• Write protection via keypad lock (
10.8.1 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

Def. access
code
2.
Define a max. 4-digit numeric code as an access code.
Ã
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.

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
• In the "Description of Device Parameters" documents, each write-protected parameter is
identified with the -symbol.
