Service manual
To carry out these tests, the dispensing system should be primed. The following is a description of the different
tests that can be performed.
4.3.2.1. Functioning test
This test makes it possible to manually switch the selected device.
4.3.2.2. Stress mode test
This test makes it possible for a certain sequence of device switching to be performed continually. The technician
can program the duration of the test, which can be cancelled at any moment.
4.3.3. Needle self-centering system test
This test makes it possible to check the functioning of the needle self-centering system. During its initialisation,
the analyzer uses this system to check the presence of the needle and its verticality and automatically correct
small deviations. The test consists of simply running this process. The technician can remove the housing of
the arm to observe the test. On the nalisation of the test, the program shows the deviation (x, y) found in the
motor steps.
4.3.4. Needle level detection system test
This test checks the functioning of the system for detecting the capacity of the needle in bottles of reagent and
sample tubes.
This test checks the functioning of the system for detecting the capacity of the needle in reagent bottles and
sample wells. The test can be performed in any position on the tray.
First select the rack type, then the position of the rack on the tray and, nally, the position of the bottle/well on
the rack. Press the Test button and the program will move the arm to the indicated position and check whether
or not liquid is detected, depending on whether the bottle is full or empty.
Repeat the test as many times as the user considers necessary.
