Using the Product with Spectral Analysis
Connect the sensor following the steps in the Getting Started section of this user
manual.
Select the Type of Data to Measure
The three options for Experiment Types are
1. Measurement
vs.
Wavelength—collect a full spectrum.
2. Measurement
vs.
Concentration—conduct a Beer's law experiment.
3. Measurement
vs.
Time—collect time-based data for a kinetics experiment.
By default, Absorbance is expanded. You can also choose from % Transmittance,
Emissions, or Advanced Full Spectrum. Use the Advanced Full Spectrum mode to
switch among all the measurement types in the same session. For complete
instructions, refer to the Spectral Analysis user manual at
www.vernier.com/spectral-analysis
Measurement
vs.
Wavelength (Full Spectrum)
1. Select Measurement

2. If applicable, follow instructions for calibration. Align the cuvette so the clear
side of the cuvette is facing the light source.
Note:
Calibration is not required
for intensity.
