Analyzing samples
Safety information
Make sure that you have read and understood section Safety information on page B-5. The
following warning messages in particular are relevant:
o Infection by biohazardous materials on page B-5.
o Personal injury or damage to the analyzer due to contact with instrument mechanism on
page B-5.
o Loss of sight on page B-6.
Incorrect results due to inadequate sample preparation
Specimen containing clots may obstruct the probe. Specimen containing bubbles or foam
may cause level detection errors and air pipetting. Consequently, incorrect results may be
generated.
Take adequate care when preparing the samples.
Incorrect results due to insufficient fluid
Insufficient fluid may lead to inaccurate pipetting and consequently to incorrect results.
Always fill the tubes with enough fluid that at least the defined dead volume of fluid is left
when pipetting is complete.

See Tubes on page A-53.
Time limit for placing samples
The system assumes that you place the sample tube that you just identified.
You need to place the sample on the sample area within 10 seconds of confirming the test
selection. Failing to place the sample tube within 10 seconds cancels the current identifi-
cation process. You will be asked to identify the sample tube again.
