6.2.4 User Login
If the multi-user feature is activated, a user must
be logged in before the user interface of the ‘ELite
5’ can be accessed. You can log in on two
different ways:
• Enter the user ID and password assigned
to your account.
• Create a new user account.
The multi-user feature of the ‘ELite 5’ analyzer
tracks which user is logged on when important
activities are performed such as sample or QC
measurements or calibration. The multi-user
feature allows full access to administrator users
while restricting regular users from actions that
change the way the ’ELite 5’ analyzer operates,
such as changing calibration settings.
See section 13.8 for more details about the user
management.
6.2.5 Pneumatic System Start and Blank Measurement
Before measuring any blood or control samples, the pneumatic system components of the
‘ELite 5’ analyzer need to be initialized and a blank measurement run and accepted. To start
the pneumatic system and run a blank measurement, click or tap the ‘Measure’ icon with the
single test tube graphic on the top left corner of the screen. The following sequence takes
place:
• The color of the ‘Start’ button changes to red.
• The reagents are primed.
• The measuring system is flushed.
• The sample-door, syringe, needle x/y movement, and shear valve motors are
activated and tested.
• The vacuum system is activated, and pump sensors and vacuum leakage is tested.
• A blank measurement is initiated automatically.
• An empty result screen is displayed.
• The blank measurement is performed.
• The results of the blank measurement are displayed.
The results of a blank measurement must be accepted before blood or control samples can
be processed. If the results from the first blank measurement are not acceptable, it does not
necessarily mean that something is wrong about your ‘ELite 5’ analyzer. Please consider the
following:
• Blood proteins or other particles can accumulate in the pneumatic tubing or
components.
