Write protection via access code
Using the device-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 via local display
1. Navigate to: Setup

2. Define a max. 4-digit numeric code as an access code.
3. Repeat the same code in

parameters.
The symbol appears in front of all write-protected parameters.
Define access code via operating tool (e. g. PACTware)
1. Navigate to: Setup
Advanced setup
Administration
Define access code
2. Define a max. 4-digit numeric code as an access code.
Write protection is active.
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.
8.2.4
Disabling write protection via access code
If the symbol appears on the local display in front of a parameter, the parameter is write-
protected by a device-specific access code and its value cannot be changed at the moment
using the local display.
Disabling write protection
The locking of the write access via local operation can be disabled by entering the device-
specific access code.
1. After you press , the input prompt for the access code appears.
2. Enter the access code.
The symbol in front of the parameters disappears; all previously write-protected
parameters are now re-enabled.
Note!
• If write access is activated via access code, it can be also be deactivated only via the
access code.
• In the "Description of Device Parameters" documents, each write-protected parameter is
identified with the symbol.
