Omegon® LRF 600 rangefinder

Congratulations on the purchase of the new Omegon® LRF 600 rangefinder. The
Omegon® LRF 600 rangefinder is used for measuring distances from 5 up to 600
metres using an invisible laser beam.

1. Included Accessories

Pulse strap and soft pouch. Battery is NOT included.

2. Getting Started

Take some time to identify the product’s parts.

1- Eyepiece;
2- Strap slit;
3- Battery cap/Battery compartment (1x CR2 Battery);
4- ON push button; Unit selection (metres/yards);
5- MODE push button; Measure type selector.

3. How to use the Omegon® LRF 600 rangefinder

3.1. How it works and limitations.

An invisible laser beam (905nm) is pointed to the target being
measured. The laser beam is reflected and the travel time
indicates the distance between observer and target. The
measurement is accurate up to 1 metre. The minimum

measuring distance is 5

metres, while the

maximum is 600 metres.
The target should be able
to reflect the laser beam.
The darker the target the
dimmer is the reflects
laser beam, with black
being the worst colour a
red reflecting surface the
best colour. The laser

beam angle is also
important. The laser beam
should be hitting the

target at 90 deg. (perpendicular to the laser beam) steep angles
provide limited readings. Sunny days interfere with the
readings and the beam range, overcast sky allows accurate
measurements. Rainy or foggy days reduce the reading range.

3.2. Using the Omegon® LRF 600 rangefinder

Release the threaded battery cap, use a coin to rotate it. Insert
the CR2 battery and make sure that the positive side points out.
Place the battery cap back and retighten it. Press the ON push
button (figure 3) for 2 seconds.

3.3. Settings for observing conditions.
Push the MODE button once to change settings to RAIN (figure

5). This should be used when it is raining or if the air is humid
(foggy) and for distances more than 60m. Pressing twice the
MODE button allows to change to REFL (figure 7). This should
be used when a target is too reflective and scatters the laser
beam. Finally pressing the MODE button once more chooses
>150 (figure 9). This is used to measure objects that are
partially covered by trees, power cables or other, target must
be at distance more than 150m. The “>150” sign flickers.

3.4. Measuring the distance.

Once the right observing conditions mode is selected (3.3) you
can start measuring distances. Press ON button continuously to
measure until LASER flickers (figure 12) and a distance is
measured and shown in the display (figure 13). The reflected
laser beam can be measured even if the reflecting conditions
are far from ideal. The quality of this reflection is shown above

the flickering LASER. Excellent reflection quality is up to 10
black triangle marks. Moderate reflection is from 4 to 8.
Mediocre is below 3.

If “_ _ _” is shown there is no laser beam reflection, the target

is too far away or too close (figure 15).
