Protecting access to instrument data

LWT instruments offer a few methods of protecting access to their data. You can set role-based
passwords (standard and advanced users) and enable instrument write-protection (software and
hardware) from the Access Control menu under the Device Setup menu.

For more information on securing your instrument from unwanted access, see "Cybersecurity" on
page 5. For security reasons, it is recommended to set passwords.

Setting up role-based passwords

instrument functions and features based on the password entered.
To define passwords:

3 In the edit window, press the Up and Down arrow keys to move right or left on the alphanumerical
ribbon and highlight the alphanumerical characters that you need to create the password.
4 Press Next to select the highlighted character and move on to the next character to highlight.
5 Repeat steps 3 and 4 until your password is complete.
6 Press Next one last time, then OK to save your password or Cancel to cancel the password that you
just created.

Resetting passwords

To reset all passwords:
1 Select Device Setup > Access Control > Reset Password.
2 Press OK.
If no passwords have been set, OK is not displayed; you can only select Back.
