Maintenance 129
The lamp energy displays as a scatter plot.
• If the points are mostly within ±40 of the center, the lamp is normal.
• Otherwise replace the lamp
11.
Only if you replaced the lamp or a cuvette segment, select Regist Data, then select
OK in the Registration window.
If not, proceed to step 12.
NOTE
The system uses the data from the lamp energy data registration as the comparison
standard for the next calculation of the attenuation ratio.
12. Exit the Lamp Energy Monitor window, then select
Initialize to switch the system
from the WAIT state to the READY state.
13. Run cell blank measurement.
Reading lamp energy data
1. Execute the lamp energy check and acquire the data.
• A graph displays at the window.
• The lamp energy check data displays to the left of the graph.
2. Select a wavelength for which to display data.
3. Display the voltage or the AD value.
4. (Optional) Change the vertical scale of the graph.
Measuring cuvette blanks
When performing weekly maintenance, be sure to perform the procedures in the
following sequence:
1. Weekly wash
2. Lamp energy check
3. Cuvette blank measurement (this procedure)
Materials required:
• No materials required
Time: 20 minutes
Analyzer mode: READY
BIOHAZARD
Wear personal protective equipment.
Use universal precautions.
Reaction cuvettes undergo changes in absorption with use. After the weekly wash,
perform the cuvette blank measurement to determine the change. The cuvette blank is
only run weekly, even if your lab runs the Weekly Wash as a daily procedure.
1. At the Menu Panel, select Maint, then select User Maintenance.
2. In the Cell blank meas.check area, select
Start CB.
The measured cuvette blank values for 221 cuvettes and a list of abnormal cells are
printed in approximately 15 minutes.
