internal pipette syringe and inform you not to place the
tip in the sample until prompted to do so. The screen
display will indicate when the analyzer is ready.
Keep the pipettor vertical (upright) during
pipetting to ensure that fluid is not drawn into the

on the chemistries. The screen will display the selected chemistries and the time
remaining. The reflective density of each slide, which is a function of the concentration
of the analyte, is measured up to 18 times during the analytical process. These
measurements are shown for each chemistry as a time curve that develops on the
screen during analysis. Three beeps signal the completion of analysis.
