8.3.2 CUVETTE WATER BLANK

cleaning.
Washers are dispensing system wash in all cuvettes and photometer records
the background measurement of each cuvette at all 12 filters. The process takes
places into two parts; at first system wash is dispensed to the first 40 cuvettes,
absorbances are read, cuvettes are then dried and then the other half of the
cuvette tray is filled and read. Process takes approximately 15 min and if accept-
ance criteria are fulfilled, cuvettes are considered clean.
1. Open the Maintenance scheduler status screen and press Perform behind
the Cuvette Water Blank function.
2. The cuvette water blank starts automatically.
3. After the cuvette water blank finished the scheduler will be updated auto-
matically. The actual and the previous results are displayed on the screen.
