Measurement
1.
Decide whether you use close-up
lens (optional) or not according to
measuring object size and distance.
See the table below for details on measuring distance
and measuring area. If you set close-up lens, lens
type setting is required in this instrument. (see p.40)
2.
Slide measuring angle selector
according to size of object and select
either aperture1˚, 0.2˚, or 0.1˚.
∗ The measuring angle select is covered with holding cap
CS-A24 (see p.8) at shipment from factory.
Pressing with finger cushion, slide
measuring angle selector slowly.
Do not operate measuring angle selector during
measurement. If measuring angle is switched during
measurement, you may fail to perform measurement
or to obtain correct measurement value.
3.
Rotate diopter adjustment ring on
finder for diopter adjustment.
Make sure that aperture (black circle indicating
measurement area) looks clear when
observing object through finder. (See p.17.)
4.
Rotate focus adjustment ring for
objective lens for that purpose.
Make sure that object around aperture looks
clear when observing object through finder.
Only measuring area for measuring object must
be placed in aperture. If extra area, which is
not measuring object, is included in aperture,
you cannot perform correct measurement.
