Bluetooth Connection
1. Install Vernier Spectral Analysis
your computer, Chromebook™, or
mobile device. See
www.vernier.com/spectral-analysis
for Spectral Analysis availability.
2. To power the Bluetooth radio,
connect the spectrometer to the USB
Power Adapter or to a powered USB
®
hub. The Bluetooth LED will blink.
Note: Do not plug the USB into a
computer USB port to run with
Bluetooth wireless technology.
3. Launch Spectral Analysis.
4. Click or tap Connect a Spectrometer.

3. The software will identify the
spectrometer and enter data-
collection mode. You are now
ready to continue your experiment.
Note: This sensor does not work with
Discovered Wireless Devices. Your
spectrometer's ID is located near the
barcode on the label. The Bluetooth
LED on the sensor will now glow
blue (no longer flashing).
5. Click or tap Done to enter data-

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 vs. Wavelength.
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.
