1
00:00:00.500 --> 00:00:10.500
To measure an absorbance spectrum, start by defining start wavelength, end wavelength and wavelength step.

2
00:00:11.000 --> 00:00:30.500
Take a reference spectrum with no sample in place. This will appear as a dotted line (axis right). 

3
00:00:31.000 --> 00:00:45.500
You can adjust light power and slit width to maximize the reference response.

4
00:00:46.000 --> 00:00:53.500
Once happy with the reference, select it as the reference spectra.

5
00:00:54.000 --> 00:01:02.500
Before taking absorbance measurement, enter the name of your sample. 

6
00:01:03.000 --> 00:01:34.500
Place your sample in the dedicated sample holder and start the absorbance measurement. 

7
00:01:35.000 --> 00:01:48.500
Measured data appears as a solid line, with absorbance axis on the left. 

8
00:01:49.000 --> 00:02:13.500
Multiple spectra can be plotted on screen simultaneously. Toggle spectra on and off using the Sample Display Window on the right. 

9
00:02:14.000 --> 00:02:30.500
This window can also be used to view data directly under the data tab.
