Measuring
WARNING
• During measurement, do not remove the optical fiber cable, because light is emitted from
the light source port. Visual impairment may occur if the light enters the eye.
• Close the covers of any light source ports that do not have optical fiber cables connected
to them. On models with two or more light source ports, visual impairment may occur if light
that is mistakenly emitted from the wrong port enters the eye.
