13.DISTANCE MEASUREMENT

Perform the following settings as preparation for distance measurement in Observation mode.

• Distance measurement mode

• Target type

• Prism constant correction value

•ppm

•EDM ALC

C"20.2 Instrument Configuration"

• It is possible to allocate softkeys in measurement menus to suit various applications and the ways

that different operators handle the instrument.

C"20.6 Allocating Key Functions"

C 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. OS

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 OS and 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.

C 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.), “

I” will be displayed in some cases, but in fact, accurate

measurement is impossible. Therefore make sure that the target center is sighted correctly.
