Auto Focusing
Use autofocus to focus to a target automatically. First ensure AF is enabled within the
onboard field software settings, then press
[AF] key.
The Auto Focusing system focuses the lens using a distance captured by the EDM. At
any time the manual focus ring can be used for precise adjustments to the focus.
The Auto Focusing system uses distance taken by EDM to drive the focusing lens to
the appropriate position. Therefore, an EDM distance is required, if the instrument is
to Auto Focus.
To best obtain the required distance for the EDM, rough sighting by optical sight
(Finder) is needed.
The focusing is based on the center of the telescope (cross-hair sighting).
After turning the focusing ring, the instrument will remain in manual focusing mode
until the
[AF] key is next pressed.
Setting the Measurement Mode and Preparing the Target
The Nikon XF Series has two measurement modes (Prism mode and Reflectorless
mode), that can be selected by the installed application software.
To set the measurement mode depending on the target you want to measure, see the
following table.
In some cases, you can measure another target that is not appropriate to the set
measurement mode.
Note – Nikon XF Series is Laser Class 1 in the Prism and Reflectorless mode, and
Laser Class 2 in Laser pointer function. Don’t sight the Prism when the Laser Pointer
is on.
