10.9 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 for the local display and Web browser (→  91)
• Write protection via write protection switch (→  92)
• Write protection via keypad lock (→  59)
10.9.1 Write protection via access code
The effects of the customer-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 via the Web browser is protected, as are the parameters for the measuring
device configuration.
