6 .3 User concept
The software recognizes two different kinds of users – the administrator, with unrestricted access to
any area and to any function of the system, and the operator, whose access is restricted to the tasks,
necessary for the routine operation of the instrument.
The operator is allowed to
• perform tasks for the system preparation and periodic tasks,
• set up and perform any kind of sample determinations,
• allocate results to result groups,
• view, filter and export results,
• calculate mean blanks,
• adapt the titer of the volumetric solutions,
• specify the protein factor for determinations.
The access to the device settings is also restricted to the definition of the result units and some other
settings (language, printer, sampler etc.)
NOTE
In case you forgot the password for your administrator account, you can ask your BUCHI service
center for a password for the BUCHI Administrator. The account of the BUCHI administrator will
always be present on your system and can not be deleted. The password will be valid for one day,
enabling the creation of a new administrator account on your system.
