Scale factor
iX calculates horizontal distance and coordinates of a point using measured slope distance. If scale factor
has been set, scale correction is carried out during calculation. When scale factor is set to "1.00000000",
the horizontal distance is not corrected.
Corrected horizontal distance (s) = Horizontal distance x Scale factor

Dist.reso. (Distance resolution)
Select distance resolution of fine measurement. Distance resolution of rapid and tracking measurement
will shift with this setting.

Tracking reso. (Tracking resolution)
Select distance resolution of tracking measurement and road measurement (N-prism only). Set this setting
depending on the measurement purpose like measuring a moving target.

EDM ALC
Set the light receiving status of the EDM. While carrying out continuous measurement, set this item
according to the measurement conditions.
• When EDM ALC is set to "Free," the instrument's ALC will be automatically adjusted if an error occurs
as a result of the amount of light received. Set to "Free" when the target is moved during measurement
or different targets are used.
• When "Hold" is set, the amount of light received will not be adjusted until continuous measurement is
completed.
• If an obstacle intermittently obstructs the light beam during continuous measurement and the "Signal off"
error occurs, each time the obstruction occurs it takes some time for the amount of light received to be
adjusted and the measurement value displayed. Set to "Hold" when the light beam used for
measurement is stable but is frequently obstructed by obstacles such as people, cars, or tree branches
etc. preventing measurement from being performed.

• When the distance measurement mode is set to "Tracking" (target is moved during distance
measurement) the EDM ALC will be adjusted regardless of the EDM ALC setting.
