Preparing the system
Preparing the system
Before you can start analyzing samples, you need to prepare the system. Preparing the
system includes both user actions and actions performed automatically by the system,
such as heating up the cuvette ring or cooling down the reagent cooler. The process is
designed in such a manner that user intervention is mainly required at the beginning
and at the end of the Prepare phase. This way, the operator does not have to stand by
the instrument the whole time.
The easiest way of performing the daily preparation tasks is to follow the Prepare
wizard.
Preventing intervention during sample processing
Performing conscientiously all preparation steps reduces considerably the chances of you
having to intervene during routine operation.
Follow the steps suggested by the wizard
You are guided through the preparation process by the Prepare wizard. This sequence of
screens shows you which actions you should perform and in which order.
Skipping a step
You may skip a step. Before you do so, remind yourself of the consequences. In many
cases, skipping a step simply means postponing the task to a more convenient time. In
other cases, skipping a step could prevent the system from performing an analysis; for
example if you chose not to replace a reagent that is low, a test that uses this reagent may
not have enough reagent.
