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
