4.2.7. Adjustment of the level detection sensitivity
This screen allows tting the sensitivity of the capa city level detection system of the probe. In order to make
the adjustment, rst of all you have to select the typs of racks: metal lled racks (grey color) or plastic racks
(black color).
Then place on it the following conguration of racks and samples:
• Paediatric Rack: place 4 paediatric glasses in positions 5, 6, 17 and 18 with 150 uL of liquid system.
• Rack of 13/15mm sample: place 4 tubes in positions 5, 6, 17 and 18 with 500 uL of liquid system.
• Rack of reagents: place 2 bottles of 20mL in positions 5 and 6 with 2mL of liquid system.
It is possible to see a graphic with the position of the tubes and racks in the screen photo. When pressing the
Adjust button, the arm takes some sensitivity readings automatically until detecting the water in each one of
the tubes. Once this operation is nished, the arm is parked in its original position and it shows the sensitivity
results of each one of the tubes. Move rack to position 5 and repeat the adjustment. Once these second rea-
dings are nished, the program calculates the average of all sensitivities; the result is the average sensitivity.
The technician should notice that the sensitivity values of each tube have to be similar; otherwise, he should
repeat the whole measurement.
Repeat this adjustment per each rack type.
The sensitivity value can also be introduced manually for each rack in the corresponding box.
Pressing the button Save, the analyser saves the new adjusted sensitivity value. Pressing the button Close,
the old value stays. Pressing the button Restore, the initial value of entry to the screen is restored. A manual
sensitivity value can be inserted in the corresponding box.
4.3. TESTS
Various tests make it possible to check that the different components of the analyzer function correctly.
4.3.1. Motor tests
Through these tests, the technician can check the correct functioning of all the analyzer motors step by step.
The screen makes it possible to choose the motor to be tested and the test that is to be carried out. The analyzer
uses the following motors step by step:
- X axis of the operating arm.
- Y axis of the operating arm.
- Z axis of the operating arm.
