This program reports the Transmittance and Absorbance measured by the colorimeter for the wavelength(s) of light selected by the user. For an example of a lab using this program see Lab 1: Introduction to Colorimetry.
With the basic program window open enter the serial port corresponding to your device in the program window and click on the “Connect” button in the lower left-hand side.
Place a cuvette with your ‘blank’ measurement (e.g. water) inside the colorimeter and click “Calibrate”. The data tables will display a value of 1.00 for Transmittance and 0.00 for Absorbance on all color channels. See Calibrating the colorimeter for more information.
Place a cuvette containing your sample inside the colorimeter and click “Measure”. The Transmittance and Absorbance tables will display the measurements corresponding to the selected color channels. In addition, a second window will automatically open, displaying a bar graph of the measurements.
