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
The Lamp Energy Monitor window displays.
2. Ensure the bottle at position #50 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
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
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

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 (
