Measuring procedure
When the unit is powered off the LCD will appear blank. To
activate the unit press and hold A button (Fig. 1) for half a
second. The word ‘READY’ will appear on the display to
indicate the unit is powered on.
Pressing the A button (Fig. 1) in Ready to Measure mode will
initiate measurement. The result of the measurement is displayed
in a form that depends on the measurement parameters (see Setup
Mode).
If a measurement is unsuccessful for any reason, four dashes (‘---
-‘) will be displayed on the LCD. For successful measurement
the target must be at least 10 m away.
If more than one parameter is chosen to measure, e.g. distance
and elevation, the results will replace each other on the display
every second.
Maximum distance
Though maximum measurement distance depends on target
reflectivity, weather conditions and other conditions, for most
relatively large targets the unit will provide accurate ranging for
up to 2,200 meters. The indicated measurement range (2,200
meters) is proven to a NATO standard target with the following
characteristics: 2.3x2.3 meters, albedo 0.3, visibility >20km.
Target reflectivity depends on its color, surface finish, size,
shape, position in relation to the laser beam and other factors.
Bright target colors are more reflective than darks. A polished
