To login, the usernames will follow the following format: class-section-station.
So, for example, if you are in PHYSICS 207, section CB2, and sitting at station 03, your username will be:
207-CB2-03
If you are in PHYSICS 203, section LM, sitting at station 8, then your user name will be:
203-LM1-08
Ask your lab instructor if you do not know what section you are in. They can also tell you the password, which is on the instructions card on the base of the computer.
