(546nm) to the desired wavelength (500nm) and automatically blank.
Note: You must blank your reference before measure any sample. Follow your lab
procedures for preparing the reference liquid and the steps below to set the blank:
2.2.4 Make a blank reference solution by filling a clean cuvette with distilled or de-

2.2.6 Set 0.000A or 100%T by pressing 0A/100%T button.
