Hello, on the VK-8000 dissolution autosampler, how can I block the date and clock function to not be changed by any mid operator?

The VK8000 has reached the end of guaranteed support.

The VK8000 does not have user options.

Here is a link to the user manual:  https://www.agilent.com/cs/library/usermanuals/Public/Agilent_8000_Op_Man.pdf

I would recommend that you speak to your local sales representative regarding an upgrade to the 850-DS.

Thanks for the help.
