14.DISTANCE MEASUREMENT
Perform the following settings as preparation for distance measurement in Basic mode.
• Distance measurement mode
• Target type
• Prism constant correction value
• Search area
• Auto Pointing/Auto Tracking

• It is possible to allocate softkeys in measurement menus to suit various applications and the ways
that different operators handle the instrument.

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. (After turning ON the laser-pointer, the
laser beam is emitted for 5 minutes, and then automatically switches OFF.)

• Make sure that the target setting on the instrument matches the type of target used. SRX
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 wiping cloth.
• During reflectorless measurement, if an object with a high reflective factor (metal or white surface)
is positioned between the SRX and the target, accurate measurement results may not be received.
• Scintillation may affect the accuracy of distance of 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.

• Manually sight the target when checking the returned signal.
• 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.
