Polarimeter asking for a login at startup
The Polarimeter should never need to be logged into at startup. If a customer or IT department has connected the Polarimeter to a domain, there is a factory ID and password to enter into the Polarimeter user interface.
If you power on the polarimeter and see this screen, follow the instructions below

1. Select "switch user"
2. Enter username: Rudolph/rraap
3. Leave the password blank "no password". Press <enter>
Once into the software, the instrument should be removed from the domain
