Laser Range Finder LS010A
Usage
Laser range finders use a low-intensity eye-safe laser to measure the
distance to a target object. Apart from regular operation Ranger LS010A
features a special mode that ignores interference from close-by objects
such as foliage and fencing, and two additional modes to ensure accurate
readings in the rain or under foggy conditions.

Mode:
a. <blank> - standard mode.
b. “RAIN” - for rainy conditions to measure distance to objects more
than 60 metres away.
c. “REFL” – for conditions of thin fog or heavy humidity.
d. “>150” – ignore interference by close-by (closer than 150 metres)
small objects such as branches, fence wires etc., that lie between
you and the target you are ranging.
The number of arrows following the word “QUALITY” shows the quality
of the ranging signal. 6 or more arrows means a good enough return
signal for a distance reading.
The word “LASER” flashes when the range finder is emitting the rangefinding beam.
“BATT” battery low indicator.
Operation

5.
Look through the eyepiece and rotate it to adjust the image so that it is
sharp and clear.
Press and release the trigger button to activate the LCD screen.
Place the target object under the centre circle and press and hold the
trigger button to read the range.
The display remains active for 15 seconds before shutting-off.
It is recommended that the object is ranged at least twice for best
accuracy by depressing the trigger button a second time for three
seconds while the display is still active.
A bad reading is indicated by three short lines “- - -” if a distance reading is
not obtained after three seconds.
You can use the “mode” button to change the operation mode from standard
to “>150”, “RAIN” or “REFL” to a) ignore interference from close-by objects
such as foliage and fencing, b) ensure accurate readings in the rain, or c)
when using the laser under foggy conditions. When switched on the unit
reverts to the mode last used.
To change the distance unit (metres / yards), press and hold the “mode”
button down for three seconds.
The maximum range a target distance can be measured is affected by the
following four variables:
-3-
1.
2.
3.
4.
The size of the object being measured,
the angle of the surface being measured with respect to the laser
beam,
weather conditions, and
reflectivity of the surface being measured.
Generally speaking you can range targets further on a clear day, with larger
targets that are highly reflective and with surfaces perpendicular to the laser
beam than you can with small light-absorbent targets standing at an angle
in misty or rainy weather.

Do not attempt to disassemble the device.
Lens surfaces should be kept clean with a soft cloth, used gently to
avoid scratching the lens coating.
Make sure the battery is inserted with correct polarity. An inverted
battery can damage the electronics.
Remove the battery for long-term storage.
Store in a cool dry place.
Operating temperature is -20°C to 40°C.
Do not depress both MODE and TRIGGER buttons simultaneously.
This device can only be repaired by qualified professionals. Please do
not attempt repair yourself. If your laser range finder becomes faulty
package it and return it to your dealer, or return to the service centre
