1.3.5 Opening/Closing the Viewfinder Shutter

When the brightness of the measurement target is extremely low or when there is a luminous body at
the viewfinder side, set the viewfinder shutter to “CLOSE” in order to block the stray light from the

viewfinder.

The shutter is opened and it is
possible to observe an object
through the viewfinder.

The shutter is closed and the
light from the viewfinder is
blocked.
