window.
13. If not, proceed to step 14.
NOTE: The system uses the data from the lamp energy data registration as the
comparison standard for the next calculation of the attenuation ratio. The displayed
attenuations for all the reference values are set to 100%, indicating no attenuation.

• 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
NOTE: 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
BIOHAZARD
Wear personal protective equipment.
Use universal precautions.
Reaction cuvettes cause 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 all RRV cuvettes and a list of abnormal cells are
available in the real-time monitor in approximately 15 minutes.
3. Select
Yes to save the data.
