1. Remove something in the measurement channel, close the sample
chamber cover, press the wavelength value, type in the wavelength of
measurement;
2. Put the Reference in the measurement channel, press the button Zero;
3. Put the Standard Sample in the measurement channel, press the
button Measure, the result is the stray light of this wavelength.
None
1. Remove something in the measurement channel, close the sample
chamber cover, press the wavelength value, type in the wavelength of
measurement, press the button Zero;
2. Press the button Measure, the result is the noise of this wavelength.
Block
1. Remove something in the measurement channel, close the sample
chamber cover, press the wavelength value, type in the wavelength of
measurement, press the button Zero;
2. Put the Block in the measurement channel, press the button Measure,
the result is the dark noise of this wavelength.
None
1. Remove something in the measurement channel, close the sample
chamber cover, press the wavelength value, type in the wavelength
500, press the button Zero;
