Distance Measurement - Sokkia 130R Series Operator's Manual

11. DISTANCE MEASUREMENT

Perform the following settings as preparation for distance measurement.
• Distance measurement mode
• Target type
• Prism constant correction value
• Atmospheric correction factor
• EDM ALC
"25.1 EDM Settings" / "25.2 Configuration -Config Mode-"
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. But in the Status
screen and when target symbol (ex.
laser beam is not automatically turned off. )
• Make sure that the target setting on the instrument matches the type of target
used. SET 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 SET 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.
