All or part of the command pool can be regrouped on a keyboard/few buttons that allow to navigate through the display menus on a monitoring screen. Some spectrophotometers are entirely controlled via a computer software installed on a personal computer. In this case, please refer to the software instruction manual.
WARNING: some more sophisticated spectrometers possess two measurement canals that work simultaneously. They are “double light beam” instruments. The values of I0 and I are determined at the same time and are compared in order to provide the desired result.
