4.3.7.6. Absorbance measurement
This test enables individual absorbance readings. The technician can choose the rotor well on which he wishes
to take the readings and ll it with the liquid he desires. He can choose which wavelength he wishes to use.
The screen shows the count number obtained, the absorbance with regard to the corresponding base line, the
value of the base line.
4.3.7.7. Reactions rotor check
The user can use this test to check the optical status of a reactions rotor. He or she can choose the optical lter
with which the test is to be performed. The technician must place the rotor in the analyzer and press the Test
button. If the Automatic Fill option has been chosen, the analyzer lls the 120 rotor wells with distilled water
and then makes a base line on each well with the chosen lter. The analyzer graphically displays the absorban-
ces related to the average of all the wells and tells the technician the state of the rotor (optimal, adequate or
unusable). After the test, the user must remove the rotor of the analyzer, empty it and dry it completely before
using it for analyses.
