1. At the Menu Panel, select
The Lamp Energy Monitor window displays.
2. Ensure the bottle at position #56 in Reagent Tray 1 (RTT1) contains deionized water.
3. Select
The Lamp Energy Monitor dialog box displays.
4. Type
5. Select
• The reagent probe aspirates deionized water from RTT1 and dispenses it into
reaction cuvette #1.
• The reaction disk rotates until cuvette #1 is in the detection position.
• The Operation window displays Lumi.Check and then WAIT.
NOTE:
6. At the Lamp Energy Monitor window, in the Luminous Energy Check area, enter the
settings:
a. Type
Enter the number of times to measure the lamp energy (normal setting: 1000).
b. Type
Enter the time (in µs) to elapse after each lamp energy measurement (normal
setting: 25).
c. Select
d. Select
7. Select
The message, "Execute the lamp energy check?" displays.
8. Select
9. On the Lamp Energy Monitor window, select
10. Calculate the scatter plot:
a. Note the value of the 340-nm AD count field.
b. Add 50 to the 340-nm AD count and type the sum in the top field to the left of
the graph, then select
c. Subtract 50 from the 340-nm AD count (noted in step 10 a) and type the
difference in the bottom field, to the left of the graph, then press
The lamp energy displays as a scatter plot.
11. Replace the lamp if any of the following is true:
• The AD points are not within ±40 of the center.
• The voltage reading (Volts column) for any of the 14 wavelengths is outside the
range 5.0 to 9.0 volts
• The attenuation [ATTENU(%) column] for any of the 14 wavelengths falls below
80%
