How do I position the CI-710 to make measurements in reflectance mode?

For reflectance measurements, the fiber optic probe should be connected to the side of the CI-710. To make measurements of the upper, axial side of the leaf, turn the instrument upside down so that the CI-710 spectrometer box and light probe are on top of the leaf. The leaf clip will attach on the bottom, abaxial side of the leaf.
