Target selection logic
On its way towards the target, laser beam may reflect from
various objects, thus decreasing ranging accuracy. The smaller,
the farther, and the less reflective is the target – the higher is the
possibility of obtaining an incorrect measurement.
To improve accuracy the unit has a built-in target selection logic,
which allows choosing what target to range: the nearest (‘first’),
the farthest (‘last’), or the most reflective (‘auto’).
This mechanism helps selecting the target when ranging from
behind the bushes, wires, through the falling snow, or in similar
conditions. Similarly it enables ranging a target in front of a
bigger object, such as a wire in front of the wall.
Note: Even with target selection logic the unit may not always be
able to range the desired target as its reflectivity may be too low
to produce enough laser beam reflections for statistically reliable
calculation. A warning will be displayed if result is not
statistically reliable. See more about target reflectivity in
Additional display information (0). This information will not be
transferred via RS-232.
Individual Measurement and Scanning regimes
The unit can operate in two regimes: (1) Individual Measurement
and (2) Scanning . In the Individual Measurement regime the unit
performs single measurement when the A button is pressed
shortly, in the
Scanning regime the unit repeatedly measures and
displays results every second while the A button is pressed.
