1. BRIEF DESCRIPTION
RANGE FINDER BINOCULARS LRB 20 000 is an advanced
!
Laser Range Finder system that provides instant distance
measurements consistently and accurately. The stereoscopic
device provides convenient observation with both eyes.
Simultaneously, the user can measure the distance to an object
without loosing Binocular of the target. Therefore, the LRB 20
000 substitutes a need for two separate devices (binocular and
range finder) combining both requirements in a single device.
Upon receipt of the range finder and prior to operation the user should
proceed as follows:
- check to see that the seals on the wooden and metallic
packaged are intact;
- Check completeness of the range finder against Section 5 of
Operating instructions;
- Check to see that the serial number of the range finder tallies
with that indicated in Sections 3, 17 to 19;
- Make sure that the optical surfaces are free from grease
stains, dirt, cracks and condensed moisture. Remove dirt and grease as
directed in item 1 of table 11.1;
- Inspect the range finder exterior for physical damage (no
cracks, dents, deep rust are admitted);
- Check the dehydrator for working condition.
If the silica gel is pink in color, replace it with the new one
taken from individual SPTA set (item 11.6.3);
- Place the battery in operation as directed in Section 16 of
Operating instructions.
(The Rechargeable battery is supplied uncharged).
To secure trouble-free operation of the range finder:
- Be prompt in replacing the Rechargeable battery by freshly
charged when the red LED in the left-hand eyepiece of the range finder
starts to illuminate;
- Keep the range finder dry at all times especially in the cold
season of the year;
- After exposure to subzero temperatures keep the range finder
at room temperature for at least two hours before unpacking and then
mop up the condensed moisture;
- While operating the range finder at temperatures above 35˚ C
and exposing to direct sunrays, attach cover AEP 42.63.021 taken from
individual SPTA set to keep away sunlight. Moistening the cover with
water is permitted to cool off the range finder.
After replacement of emitter and (or) control circuit board make entries
in Section 4 of Operating instructions as to their new serial numbers
and basic characteristics.

5. APPEARANCE OF THE DEVICE
5.1. As it is set up for operation, binoculars range finder LRB 20
000 (see Fig.1) is essentially range finder 1 mounted on Angular Mount
2 . The latter is mounted on tripod 3.
5.1.1. Range finder (Fig.2) is intended for terrain observation and
measuring the distance to the closest or next-in range target caught in
the beam.
The range finder works on the principle of measuring the light
pulse round-trip time.
The measurement result is displayed in meters on digital range
indicator and also stored in the computer in binary code for further
calculations.
The schematic circuit diagram of range finder (Fig.3) shows
Rechargeable battery designated (G1), controls designated (S1- S4),
pumping and firing elements (ref. designations C1-C3, E1, L1, T1, V1V2), control circuit board (A1), display circuit board (A2), counter
circuit board (A3), and photodetector assembly (A4).
Toggle switch S1 is operated to energize the range finder, and
toggle switch S4 – to light up the light-emitting diode (LED) H1 which
illuminates the reticule pattern.
Button switches S2 and S3 labeled (MEASURE 1) and
(MEASURE L) respectively are used to prepare the range finder for
taking a measurement (by depressing one of those buttons), and to
perform the measuring operation (for which the button is released).
Button S2 is operated to range the closest target, whereas
button S3 is used to engage the next-in-range target caught in the beam.
Connector X1 couples the controls and the Rechargeable battery
to control circuit board (A1).
C1 and C2 are energy storage capacitors placed in the pumping
circuit. They are charged up to 700-1000 V through a special contact
designated A on control circuit board A1. Capacitor C3 and diodes V1, V2
are placed in the pumping circuit to prevent RF oscillations or reversal of
the voltage polarity across capacitors C1, C2. E1 – is a pumping flashtube.
Transformer T1 produces 10-15 kV firing voltage pulses to be fed to tube
E1. For the purpose, the primary winding of the transformer is furnished
with a negative voltage of 130 to 185 V fed from control circuit board A1.
The flashtube is externally fired, that is, the firing voltage pulse is fed to
the metal-clad envelope of the tube E1.
On circuit board A1 are mounted the DCC, AC ckt, power
supplies of the TIC and PhD assembly, and one circuit to analyze the
battery charge.
On counter circuit board (A3) are arranged the counting-logic
circuit of the TIC and the TSGC of the PhD assembly.
A2 is the information display assembly board. Arranged thereon
is the indicating circuit of the TIC: digital range indicator, multiple target
indicator, outgoing pulse absence indicator, ranging readiness indicator
(green) and battery discharged condition indicator (red). Through display
circuit board A2 control signals and supply voltages are fed from control
circuit board A1 to circuit board A3 and to the PhD assembly.
Circuit boards A1, A2 and A3 are connector-coupled with the
PhD assembly.
Plug X2 couples the cable of the remote control set to receive
range data in binary code.
5.1.2. Angular Mount (Fig. 4) is intended for mounting range finder on a
tripod, to lay the range finder on the target and to read the azimuth and
elevation. The Angular Mount (AI) is essentially body 15, which incloses
the elevation, and azimuth worm gear drives.
To lay the range finder accurately on the target, adjustment
knobs 1 and 7 are rotated. To coarsely lay the range finder, it is turned
through the desired angle. For the purpose, normally engaged clutches are
provided in the elevation and azimuth drives.
The angles are read on azimuth circle 14 and scale 5, with
verniers provided to make it accurate to 1/10 of a division.
Lenses 6 and 10 also contribute to the reading convenience and
accuracy. Azimuth circle 14 may be set to zero with knob 11 locked in this
position. The horizontal adjustments are made on the Angular Mount by
using level 13, and the magnetic meridian orientation is achieved by the
use of compass 8.
The range finder is fitted on to the guides of bracket 3 of the AI,
and secured thereon by means of lever 2. The clamping assembly allows
adjustment of retainer 4 by rotation of nuts 9.
The AI is installed on the tripod through the use of ball mount 12.
5.1.3. The tripod mount (Fig.5) is designed to adjust the height of the range
finder and Angular Mount as required for the particular lay of the ground.
The tripod consists of three telescoping legs 3 whose top sections are
assembled with one common base 2. Each leg may be deflected through the
angle desired relative to the base. Mounting head 1 is provided
on the base to fasten the AI. Retracting or extending the moving section
adjusts the length of each leg. For the purpose, collet nut 4 is first loosened.
In the bottom portion of the head is a stay block designed to
secure the AI on a log, a stump of a tree or any such piece of wood suitable
for the job.
6. SAFETY PRECAUTIONS
6.1. Range finder is an opto-electronic device emitting high-
density pulses of dark light at wavelength of 1.06 µm, characterized by
the following dangerous factors according to GOST 12.1. 040-83:
- direct laser radiation;
- mirror-reflected laser radiation;
- diffuse-reflected laser radiation.
Direct and mirror-reflected laser radiation of range finder is
dangerous for eyes at 1700 m distance from range finder when
observing with the naked eye.
Diffuse-reflected laser radiation is dangerous at 0.43 m
distance from reflecting surface.
When observing laser radiation through optical devices these
distances increase according to optical device magnification ratio.
Laser radiant energy density at the outlet of range finder
exceeds permissible level for skin on 16% and when decreasing it
reaches permissible level at 3.77 m distance from range finder.
6.2. According to the degree of laser radiation danger the
range finder pertains to third class laser by GOST 12.1.040-83.
NEVER:
- Binocular switched-on range finder on the friendly personnel and
materiel;
- Measure distance through window and door glasses;
- Measure distance to mirror-reflecting surfaces (mirrors, car and
building windows, optical components, grinded and polished
surfaces), which are nearer to range finder than 1700 m;
- Direct radiation to diffuse-reflecting surfaces (walls, curtains,
papers), which are nearer to range finder than 0.43 m;
- Inspect the range finder optical components on the housing side
with MEASURE 1 or MEASURE L button depressed.
6.3. Persons who happen to be in a dangerous zone of laser
radiation due to production necessary must put on goggles ZН22-72-
СZС-22-6 GOST 12.4.013-75 or ОZP for eyes protection.
6.4. Admitted to work with the range finder are the following
persons:
- Those who reached the age of 18 years old and have no
medical contra-indications on operation with laser emission;
- Instructed on and having studied safe methods of operation
with the range finder according to safety rules;
- Appointed responsible for safe operation of the range finder
by order of the leader of organization where the range finder is used.
6.5. Generated in assemblies and units of the range finder
during its operation is life-hazardous high voltage.
NEVER disassemble the range finder with the power cut in.
Repair the range finder only in specialized shop.
6.6. Between operation periods, be sure to cover the range
finder objective lens with special cap fastened to its housing.
6.7. The persons operating the range finder should be
instructed on methods of giving first medical aid when laser emission
affects eyes and skin.
7. PREPARING FOR USE
7.1. Choose an observation post.
7.2. Rotate the objective frame to bring the reticule in sharp focus.
7.3. Check range finder for proper operation:
- Battery voltage;
- The range finder for proper functioning.
7.3.1. To analyze the battery voltage, set the ON-OFF selector switch to
the ON position and check if the Low Battery indicator glows red in the
left-hand eyepiece. If it does, replace the battery.
BEFORE REPLACING BATTERY, SET SELECTOR TO OFF.
7.3.2. To check the range finder for proper functioning, proceed as
follows:
- Binocular the range finder on the target;
- set the ON-OFF selector switch to ON;
- depress the MEASURE 1 button;
- as the readiness indicator comes on, release the MEASURE 1
button and read the measured range;
- compare the range measurement result with the actual
distance.
The range finder is in good working order if the range measurement is
accurate to 5 m.
If no precise target range is available, the range finder is checked for
proper functioning by measuring the range three times on the same
target. The range finder is functioning properly if the measurements
differ within a maximum of 5 m. In the absence of the returned signal,
zeroes are displayed in all the digit positions of the range indicator
(00000). In the absence of the outgoing pulse, zeroes are displayed in
all the digit positions and the decimal point, in the third position.
7.4. To use AI and tripod for observation, proceed as follows:
Arrange the tripod on selected site;
Extend the telescoping legs at the desired length so that one of
them aligns with the ranging direction. Level the base as far as
practicable.
In case you do not use the tripod proceed as follows:
- unscrew the ball-mount seat from the tripod base;
- fit the stay block on to the wooden object and tighten it up pressing
lengthwise.
- The AI is installed and leveled through the use of ball-mount by
turning AI in ball-mount seat and putting the level bubble into the
center of ring marks.
- Secure AI by clamp.
- Sliding the range finder along the AI bracket guides, fit the AI
clamp into the T-shaped opening in the range finder bracket, and
turn the handle of the clamp to lock the range finder in position.
7.5. Use the AI compass or the reference directional angle to align the
range finder with the base line.
7.5.1. To align the range finder with the base line, proceed as follows:
find the base reference (BR) from the formula:
Where α
BR = α
is the base line directional angle;
base
α
is the directional angle of the given reference line;
ref
base
– α
± 30.00’
ref
Binocular the range finder on the reference point;
rotate the azimuth dial to align the base reference value read
thereon with the venire zero. Now, the range finder is aligned with the
base line within 30.00 mils;
turn the clamping handle to lock the azimuth dial in position.
7.5.2. To orient the range finder by using the reference directional
angle, proceed as follows:
- Binocular the range finder on the reference point whose
directional angle has been known;
- rotate the azimuth dial to set the reference directional angle;
- turn the clamping handle to lock the azimuth dial in position.
With the range finder thus oriented, the measurements are taken from
the location point relative to the directional angle of the object
(reference object).
7.5.3. For the magnetic orientation of the range finder, proceed as
follows:
- Unscrew the plunger knob all the way out to release the
magnetic needle of the compass;
- Turn the AI about the vertical axis to obtain precise
alignment of the index mark of the circle with the magnetic
needle;
- Operate the azimuth dial to set the magnetic azimuth index
correction as specified in Section "Basic Specifications" 4 of
the present Operating instructions.
When using the compass to orient the range finder, bear it in mind that
the nearby objects of iron or steel affect the indexing accuracy of the
magnetic needle. See that motor vehicles, bulldozers and such like
objects are at least 10 m away, medium-size objects (pick hammers,
crows, etc.) are at least 0.5 m away, and small-size things (flash-light,
knife, screwdriver, etc.) are 20 cm away from the instrument.
7.6. To check the range finder for proper operation when using the AI
and the tripod:
- Check the AI zero elevation reference (ER "0");
- Check the AI compass.
-
ER "0" is the setting of the elevation scale that corresponds to the
horizontal position of the range finder Binocular axis.
7.6.1. To check the zero elevation reference, proceed as follows:
- Stick a stake 50 to 100 m away from the unit and mark it with the
range finder objective height above the ground level;
- Binocular the reticule cross-hairs on the stake to read the tilt angle
(A1);
- Swap the range finder and stake positions, and apply another mark
to the stake in accordance with the new height of the range finder
objective;
- Binocular the cross-hairs on the new mark of the stake and read
again the tilt angle (A2);
- Find the ER "0" from the formula:
A1 + A2
ER "0" = ————,
2
The A1 and A2 values are reckoned in with their respective signs.
If the ER "0" value is other than zero, the respective correction is to be
taken into account while operating the range finder. The error value is
subtracted from the elevation measurement if on the positive side, and
added if negative.
7.6.2. To check compass, set up the AI for operation. Then, check the
sensitivity and balance of the needle.
For the purpose proceed as follows:
- Level the AI;
- Encage the needle;
- Unbalance the needle by using a knife, screwdriver and the like.
To make sure that the needle is free from defects, check that:
- The needle oscillates in a smooth and uniform manner to regain
balance;
- The position of the needle end is the same relative to the mark when
the needle settles;
- The needle ends are level with the marked plates within ± 0.5 mm.
The compass needs triple checking. If even a single requirement is not
satisfied, turn in the AI for repair.
7.7. After the check set the controls to their initial positions, namely:
- The ON-OFF and ILLUM. selector switches, to the OFF position.
8. OPERATING PROCEDURE
8.1. The range finder is designed to:
- survey the ground;
- range fixed targets;
- range moving targets;
- take azimuth and magnetic azimuth measurements;
- take elevation and vertical angle measurements;
- find polar coordinates of targets and reference objects;
- convert the polar coordinates of the target and reference
object into rectangular coordinates, and find the target and observation
post coordinates from the predetermined reference coordinates.
8.2. To use the range finder for ground surveillance, proceed as
follows:
- gripping the range finder with both hands, Binocular it coarsely in
azimuth and elevation on the objects to be observed;
- mount the range finder on the AI and rotate the azimuth and
elevation knobs to smoothly scan the ground or lay the range
finder on the target (reference object).
-
8.3. When ranging fixed targets, proceed as follows:
- set the ON-OFF selector switch to the ON position;
- lay the range finder on the target so that the latter, or its visible
portion is observed in the central gap of the reticule as close as
possible to its center, and the screening objects (that is, bushes,
trees, terrain elevations, buildings and such like closer-range
features located near the target or partially masking it) are beyond
the gap.
When aiming the range finder at open-ground targets, see the target in
the lower portion of the gap, touching the bottom mark of the reticule;
- depress the MEASURE 1 button, wait until the readiness
indicator comes on and release the button taking care not to upset
the aiming;
- read the measured range.
The measured value is displayed in the range indicator for 3 to 5
seconds.
With several targets being on beam of the range finder (that is,
observed in the reticule gap), the decimal point is displayed in the least
significant digit position of the range indicator. In this event, the range
finder may be used as aimed, to range the first or the last target by
depressing the MEASURE 1 or MEASURE L button respectively.
If practicable, repeat the target ranging once or twice. If the obtained
range is correct, at least two results will not differ by more than 5 m.
8.4. To range a moving target, proceed as follows:
- Observing the target through the Binocular eyepiece, aim the
range finder to track the target in elevation and azimuth;
- depress the MEASURE 1 button (or MEASURE L button, when
engaging the last-in-range target);
- As the readiness indicator comes on, aim the range finder at an
off-set point forward of the target;
- As the target aligns with he reticule gap, release the MEASURE 1
(MEASURE L) button;
- Read the measured range.
8.5. To take azimuth and magnetic azimuth measurements, proceed as
follows:
- Align the vertical mark of the Binocular objective reticule with
the right-hand object;
- Read and note down the azimuth dial indication accurate to 1/10
of a division on the vernier;
- Align the vertical mark of the reticule with the left-hand object
and read the angle again;
- Determine the measured angle.
Measure the angle by subtracting the latter value from the former one.
Add 60.00 mils to the former value if exceeded by the latter one.
During the magnetic orientation of the range finder, the angles
read off the azimuth dial are the magnetic azimuth values (bearings) of
the target (or reference object).
The magnetic azimuth correction is to be inserted (see under
7.5.3.).
If the measurement has to be precise, take 3 or 4 angle
measurements to calculate the mean value. After each measurement of
the magnetic azimuth value (bearing), upset the range finder orientation
and change the azimuth dial reading.
An azimuth or magnetic azimuth measuring under 0.80 mils
may be read off the reticule with a maximum accuracy of 0.05 mils
(small division value of the reticule is 0.05 mils, large division value is
0.10 mils).
8.6. To measure vertical and elevation angles, proceed as follows:
- Align the horizontal mark of the range finder Binocular reticule
with the upper object;
- Read the vertical angle scale using the vernier and note down the
reading;
- Rotate the azimuth and elevation knobs to align the horizontal
mark of the reticule with the lower object and read the scale
again;
- Determine the vertical angle by subtracting the smaller value
from the greater one if both have the same sign (are of the same
color), or by adding them, if the signs are opposite.
The elevation is measured with reference to the Binocular axis of the
range finder. Hence, the range finder should be thoroughly leveled
before taking the elevation measurements.
Vertical angles up to 0.80 mils and elevation angles falling
within ± 0.40 mils may be read off the reticule with a maximum
accuracy of 0.05 mils.
8.7. To determine the polar coordinates, proceed as follows:
- Use the compass to orient the Angular Mount as directed under
7.5.3;
- Binocular the range finder on the object;
- Read the azimuth of the object;
- Range the object as directed under 9.3.
8.8. To convert the polar coordinates into rectangular coordinates,
proceed as follows:
- Remove the coordinate converter from the case;
- Release the clamp and detach the rule from the reverse side of the
plotting board;
- Determine the polar coordinates of the reference point and the
target as directed under 9.7 and note them down on the plotting
board or a special card;
- Calculate from the determined magnetic azimuth A
of the
m
reference point and the target to find the directional angles, reckoning
in the compass correction ∆ A obtained from the formula:
α = Am – ∆ A
m
Read the compass correction ∆ A
of the map;
m
- Note down the reference point target directional angles on the
plotting board of card;
- Mark numbers of the plotting board with respect to the selected
scale (1:25, 000 or 1:50,000) and the reference point, observation
post and target location;
- Read the rectangular coordinates of the reference point from the
