Measurement with a prism
Do not use a prism with scratches, a dirty surface, or a chipped center. Prisms with
thin edges are recommended.
As the NPL-322 is extremely sensitive, multiple reflections on the prism surface can
sometimes cause a significant loss in accuracy.
To maintain the accuracy of your measurements:
Target Target setting
Prism, reflector sheet Prism (Prism mode)
Other (reflective materials) N-Prism (Reflectorless mode)
thin edges
chipped center thick edges
