TIL 2578: How do I get an A260/A280 value with your UV-vis spectrometers in Logger Pro?
TIL 2589: Why is the absorbance reading on my device (spectrometer/colorimeter) unstable or nonlinear at values above 1.0?
TIL 2224: Do you have instructions on how to use a spectrophotometer to conduct the Photosynthesis lab?
TIL 2553: Why can't I see better Hydrogen emission lines with my spectrometer?

Specs are different for each Spectrometer. See:

     In Absorbance mode? Yes.
     In Emission mode? No.

-Calibration process for Absorbance mode: Use a USB cable to connect the Spectrometer to a computer. Run Logger Pro 3.6 (or newer). Select Calibrate from the Experiment menu. Follow the instructions in the Calibrate dialog box.
