just created.

Preventing unwanted deletion of data

To prevent inadvertent or malicious overwriting of an instrument's settings and data, you can enable
software and/or hardware write protection; both are disabled by default.
Software write-protection
To enable software write-protection:
1 Select Device Setup > Access Control > Write Protect > Software WP.
2 Press Edit
3 Highlight On and press OK.
Data is now protected against erasing operations.
Hardware write-protection
NOTICE
Activating hardware write-protection prevents all forms of external access to the
instrument (HART, DTM, service access, etc.)
To enable hardware write-protection:
1 On the instrument head, unscrew and remove the nameplate. This exposes two buttons and the
write-protection screw.
