You must run the DataMate program to turn the colorimeter on. The colorimeter will measure absorbance in a default wavelength of 470nm. A green light illuminates to signify which wavelength is selected. Allow the colorimeter to warm up for 5 minutes before beginning any experiment.

Be sure that the clear side of the Cuvette is facing forward and backward in the colorimeter and the striated sides face to the side. Push the > key on the colorimeter and hold it down until the green light changes to 565nm. This signifies that this new wavelength has been selected.
