Zeroing the Broad Spectrum Light Sen-
sor
1. Attach the shutter to the sensor and mount the sensor to
an experimental apparatus.
2. With the 8-pin cable, connect the Broad Spectrum
Light Sensor to any analog channel (A, B, or C) on the
ScienceWorkshop interface (Figure 4). (Note: The
sensor also plugs directly into any analog channel.)
5. In DataStudio, click the Start button to begin
collecting data.
The TARE button on the top of the sensor is for
zeroing the sensor. Zeroing is particularly useful at
high gain settings where small voltage offsets may
interfere with measurements.
Note: This instruction sheet was written assuming that
the user has a basic familiarity with DataStudio
software. Users can gain basic skills by working
through the tutorial in the DataStudio sofware.

3. In DataStudio, set up your experiment in the
Experiment Setup window.
4. Select a gain setting on the sensor box. If you expect
the light intensity levels in your experiment to be dim,
move the gain switch to either 10x or 100x. If you
expect the light intensity levels to be bright, adjust the
gain setting to the 1x position.
