12.DISTANCE MEASUREMENT
Perform the following settings as preparation for distance measurement in Observation mode.
• Distance measurement mode
"19.2 Observation Conditions - Dist"
• Target type (including prism constant correction value and aperture information)
"19.3 Observation Conditions - Reflector (Target)"
• ppm
"19.4 Observation Conditions - Atmosphere"
• Auto Pointing/Auto Tracking relating items
"10.1 Auto Pointing and Auto Tracking Settings"
• It is possible to allocate Operating icons in measurement menus to suit various applications and the ways that
different operators handle the instrument.
"19.12 Allocating Operating Icons"
Caution
• When using the laser-pointer function, be sure to turn OFF the output laser after distance measurement is
completed. Even if distance measurement is canceled, the laser-pointer function is still operating and the
laser beam continues to be emitted.
• Make sure that the target setting on the instrument matches the type of target used. The instrument
automatically adjusts the intensity of the laser beam and switches the distance measurement display range
to match the type of target used. If the target does not correspond to the target settings, accurate
measurement results cannot be obtained.
• Accurate measurement results cannot be obtained if the objective lens is dirty. Dust it off with the lens brush
first, to remove minute particles. Then, after providing a little condensation by breathing on the lens, wipe it
off with the silicon cloth.
• During reflectorless measurement, if an object obstructs the light beam used for measurement or an object
with a high reflective factor (metal or white surface) is positioned behind the target, accurate measurement
results may not be received.
• Scintillation may affect the accuracy of distance measurement results. Should this occur, repeat
measurement several times and use the averaged value of the obtained results.
Check to make sure that sufficient reflected light is returned by the target sighted by the telescope. Checking
the returned signal is particularly useful when performing long distance measurements.
Caution
• The laser beam is emitted during returned signal checking.
• When the light intensity is sufficient even though the center of the reflective prism and the reticle are slightly
misaligned (short distance etc.), “
” will be displayed in some cases, but in fact, accurate measurement is
impossible. Therefore make sure that the target center is sighted correctly.
PROCEDURE
1. Accurately sight the target.
