PRODUCT DESCRIPTION
Measuring through a pane
When measuring through a pane, one unique factor to remember is that different light
reflections can occur, either from aspects directly on the pane (e.g., from contamination
or scratches) or from reflections on the pane (i.e., caused by objects behind or next to the
NAV210). Reflections of objects on the pane must be shadowed.
