IMPORTANT
Do not touch or turn the reaction tray at any time during the lamp energy check
procedure. The reaction tray should turn freely. If the reaction tray is shifted, repeat the
procedure, since a shift could result in an erroneous lamp energy reading.
1. At the Menu Panel, select
Maint, then select Lamp Energy Monitor.
The Lamp Energy Monitor window displays.
2. Ensure the bottle at position #50 in Reagent Tray 1 (RTT1) contains deionized water.
3. Select
Check Energy.
The Lamp Energy Monitor dialog box displays.
4. Type
50 in the RTT1 bottle posi. field, then select 3: 70 mL for the Container field.
5. Select
Meas. Start.
• 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
Perform steps 6 - 10 while in the WAIT state.
6. At the Lamp Energy Monitor window, in the Luminous Energy Check area, enter the
settings:
a. Type
1000 in the Meas. times field.
Enter the number of times to measure the lamp energy (normal setting: 1000).
b. Type
100 in the Meas. cycle field.
Enter the time (in µs) to elapse after each lamp energy measurement (normal
setting: 100).
c. Select
AD.
d. Select
Auto.
7. Select
Meas. Energy.
The message, "Execute the lamp energy check?" displays.
8. Select
OK.
9. On the Lamp Energy Monitor window, select
Collect Data.
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
Enter.
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
Enter.
