CAREFULLY READ ALL THE INSTRUCTIONS BEFORE USING! FAILURE TO OBEY THE INSTRUCTIONS WILL VOID THE WARRANTY AND MAY CAUSE INJURY! 1. BRIEF DESCRIPTION The LRF Modules use the same electronics and optics as rangefinder monoculars and binoculars. These modules can add various range finding capabilities into host systems: distance & speed measurement, azimuth and elevation measurement. The modules have a built-in computer interface, which enables immediate data acquisition by any system

Principle of work The Modules send invisible, eye safe laser pulses to the target. Pulses reflected from the target are captured and processed by the digital circuitry. The time-of-flight delay between the sent and received pulses allows calculating the distance to the target. A built-in digital compass/inclinometer of MOD 4EC measures target’s azimuth and elevation simultaneously with ranging. Key Features Selection of the first, last or the most reflective target Distance is dis

5. OPERATION INSTRUCTIONS Maximum distance Though maximum measurement distance depends on target reflectivity, weather conditions and other conditions, for most targets the unit will provide accurate ranging for up to 3,000 meters. In good conditions a highly reflective target can be measured up to 4,000 meters. Target reflectivity depends on its color, surface finish, size, shape, position in relation to the laser beam, etc. Bright target colors are more reflective than dark ones. A p

The correspondence between the pressing of the buttons and the signals sent via RS-232 is described in Interconnectivity, chapter 7. The rest of this manual describes measurement procedures and setting measurement parameters through pressing of the buttons. Measurement procedure When the Module is off the LCD is blank. To activate it press and hold for one second the Action (A) button. At start the module comes into the Ready to Measure mode indicated by the word ‘READY’ on the displa

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

To activate the Scanning regime press and hold the A button in Ready mode. The unit will work in the Scanning regime while the A button is pressed. Scanning or Individual Measurement regimes are available for any selected mode of measurement. When two parameters are measured in the Scanning regime though both will be quickly displayed, the second one may be difficult to register by eye. Nevertheless all data is recorded and may be recalled (see Data Recall mode for details.) Operatio
