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.
Verifying Noise (0A)
Select Tab Noise (0A) in the Performance verification interface.
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;
2. Press the button Measure, the result is the noise of this wavelength.
Verifying Noise (0%T)
Select Tab Noise (0%T) in the Performance verification interface.
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;
2. Put the Block in the measurement channel, press the button Measure,
the result is the dark noise of this wavelength.
Verifying Stability
Select Tab Noise in the Performance verification interface.

chamber cover, press the wavelength value, type in the wavelength
656.1;
2. Press the button Measure, the result is the bandwidth.
Important information The cuvettes must be clear and there’s no remains of the
samples on the surface of it. Only Silicon (Quartz) cuvettes are permitted to be used in the range of
UV area.
