10.8 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 write protection switch
• Write protection via keypad lock
10.8.1 Write protection via access code
The effects of the user-specific access code are as follows:
• Via local operation, the parameters for the measuring device configuration are write-
protected and their values can no longer be changed.
• Device access is protected via the Web browser, as are the parameters for the measuring
device configuration.
Defining the access code via local display
1. Navigate to the Enter access code parameter.
2. Define a max. 16-digit character string comprising numbers, letters and special
characters as the access code.
