Digital Viewfinder (3x zoom)

The instrument has a built in camera that displays the
target in 16 grayscales on the camera. With the cros-
shairs blended in, targets can be aimed at and accu-
rately measured, even if the laser is not visible. Refer
to piture {G}.
The integrated camera is a great help outdoors and
can be used for every function. Long distance measu-
rements and accurate measurements to small areas,
can be made even in bright sunlight without any
problems. The 3- fold zoom supports the individual
magnification.
Press the DIGITAL VIEWFINDER - key {A, 2} and the
camera is activated. Press the DIGITAL VIEWFINDER
- key {A, 2} repeatedly to switch from 1-fold to 2-fold
to 3-fold zoom.
The PLUS - key {A, 3} and the MINUS - key {A, 11}
adjust in steps 9-1 the brightness of the camera.
Whenever a distance measurement is triggered, an
hour glass symbol appears in the lower left corner of
the display screen until the measurement is
completed.
For measurements of less than 5 meters, using the
digital viewfinder is not recommended as the laser is
not centered because of the parallax.

Tilt

The instrument has a built in tilt sensor with an accu-
racy of ± 0.15° in reference to the laser beam. Acti-
vate the tilt sensor with the TILT- key {A, 10}. While

measuring, the tilt is now displayed in the upper right
of the screen. The housing can also be held at a tilt.
By pressing the DIST - key {A, 1} the tilt is stabilised
and displayed in an intermediate row. The tilt measu-
rement works independently of the distance measu-
rement.
Please make sure that the instrument is not traverse
tilted when making a tilt measurement. If the trans-
verse tilt is too large, an error message is displayed
to prevent measuring errors. The units can be set
under MENU. Refer to picture {H}. You need to
consider the height difference, between the housing
and the laserpoint, by marking off the tilt with help of
the laser beam.

Illumination

Pressing the ILLUMINATION - key {A, 13} turns on/
off the display backlight.

Measuring reference

If the positioning bracket is folded out, the device
recognizes the position, adapts the reference and
calculates distances accordingly.
The default reference setting is from the rear of the
instrument. By pressing the REFERENCE - key {A, 8},
the setting can be changed, so that the next measu-
rement taken will be from the "front" of the in-stru-
ment. Afterwards the reference setting automatically
defaults back to rear. See picture {I}.
You can choose the "front" reference permanently by
pressing the REFERENCE - key {A, 8} longer. Press
