procedure 1: alignment of lamp using analyzer Maintenance (f8)
8. Turn On the Analyzer.
9. Pipette into cuvette
38 - 500 µl of dist. water.
10. Go to Maintenance (f8) – Reaction Measurement System .
11. Execute command [plate Home ] .
12. Select
[test fotometer]
and press START
Š
.
13. The photometer will read continuously at 340 nm for about 80 sec. On the
line right of the “Test Fotometer” will be displayed the % Transmission. Use
the ADJ Horizz. Knob to obtain the maximum value, loosening screws (3 or
4) and rotate the ADJ Vertic. Knob (1 o 2) to maximize the value. Lock the
lamp with its blocking screw. If necessary repeat the alignment to obtain an
optimum value of 60% to 90%.
14. Repeat this test for each of the 8 filters, making sure that the value obtained
is above the 60% and less then 90%.
15. Insert the second lamp – wait at least 1 min to stabilize the lamp.
16. Repeat the operations as above starting with point 12 to align the second
lamp.
17. To align the signal of the two lamps, select the lamp with the higher signal
and reduce it accordingly using the adj vertic. knob.
When finished reinsert the side panel.
procedure 2: lamp alignment using the diagnostic program – tester exe.
The same alignment operations can be made using the Tester exe. in the Service
Disk.
18. Turn ON the Analyzer, as soon as the Window display appears, press the
“CTRL” key until the program is loaded.
19. Insert the disk into drive A; click on “ floppy a “ and proceed with program
“
teSteR.eXe
“.
20. In section “ Cuvette ” click in succession on [pWR on], [HoMe z], [HoMe
plate], [HoMe filteR] .
21. Click on [photometer] to open window „Figure 45“.
22. Pipette into cuvette
38
some 500 µl of dist. Water
23. Click on [WateR b] to display the decimal value of transmission under the
Water B column. (the values have to be larger then zero).
24. Click to select [filter 1] and press [Move filter] .
25. Click on
CHeCkboX 
on the right and then on
[Read one]
to activate the
continuous reading with filter (340nm).
26. Adjust knob adj Horizz. to maximize the value indicating in “READINGS”.
if all the values are lower then
39.000 or higher then 60.000,
it is possible to adjust the sensiti-
vity of the amplifier using the pR1
of the adC p/n eb0089.01 board.
See Chapter 7. if one or more fil-
ters are less then 39.000 or more
then 60.000, it will be necessary
to equalize those interference fil-
ters. (see „18.4.2 to equalize and
Replace filters“).
„table 14“ displays the con-
version values between the
different measurements.
