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 (® ä 73)
• Write protection via lock switch (® ä 74)
• Write protection via keypad lock (® ä 42)
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 ® 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.
