Connector X1 couples the controls and the Rechargeable battery to  
control circuit board (A1).  
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.  
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.  
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. The length of each leg is adjusted by  
retracting or extending the moving section. For the purpose, collet nut 4 is  
first loosened.  
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.  
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.  
- 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. 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;  
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.  
- 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 excedes  
permissible level for skin on 16% and when decreasing it reaches  
permissible level at 3.77 m distance from range finder.  
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.  
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 disassemble the range finder with the power cut in.  
Repair the range finder only in specialized shop.  
NEVER:  
6.6. Between operation periods, be sure to cover the range  
finder objective lens with special cap fastened to its housing.  
- 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;  
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.  
7.4. To use AI and tripod for observation, proceed as follows:  
Arrange the tripod on selected site;  
7. PREPARING FOR USE  
7.1. Choose an observation post.  
7.2. Rotate the objective frame to bring the reticle in sharp focus.  
7.3. Check range finder for proper operation:  
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.  
- battery voltage;  
- the range finder for proper functioning.  
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.  
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:  
-
The AI is installed and levelled through the use of ball-mount by  
turning AI in ball-mount seat and putting the level bubble into the  
centre of ring marks.  
-
-
Secure AI by clamp.  
- Binocular the range finder on the target;  
- set the ON-OFF selector switch to ON;  
- depress the MEASURE 1 button;  
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.  
- 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.  
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:  
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.  
BR = α base α ref ± 30.00’  
where α base is the base line directional angle;  
α ref is the directional angle of the given reference line;  
Binocular the range finder on the reference point;  
rotate the azimuth dial to align the base reference value read  
thereon with the vernier 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.  
-
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:  
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;  
-
-
-
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 reticle 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;  
-
-
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:  
-
-
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:  
-
-
-
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.  
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:  
When using the compass to orient the range finder, bear it in mind that  
the indexing accuracy of the magnetic needle is affected by the nearby  
objects of iron or steel. 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:  
-
-
-
level the AI;  
uncage the needle;  
unbalance the needle by using a knife, screwdriver and the like.  
-
-
check the AI zero elevation reference (ER "0");  
check the AI compass.  
-
To make sure that the needle is free from defects, check that:  
8.3. When ranging fixed targets, proceed as follows:  
-
-
-
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;  
-
-
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 reticle as close as  
possible to its centre, 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.  
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.  
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 reticle;  
-
depress the MEASURE 1 button, wait until the readiness  
indicator comes on and release the button taking care not to upset  
the aiming;  
8. OPERATING PROCEDURE  
8.1. The range finder is designed to:  
-
read the measured range.  
- survey the ground;  
- range fixed targets;  
- range moving targets;  
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 reticle 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:  
- 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).  
-
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);  
-
-
8.6. To measure vertical and elevation angles, proceed as follows:  
-
-
-
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 reticle gap, release the MEASURE 1  
(MEASURE L) button;  
-
-
-
-
align the horizontal mark of the range finder Binocular reticle  
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 reticle 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.  
read the measured range.  
8.5. To take azimuth and magnetic azimuth measurements, proceed as  
follows:  
-
-
-
-
align the vertical mark of the Binocular objective reticle 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 reticle with the left-hand object and  
read the angle again;  
determine the measured angle.  
The elevation is measured with reference to the Binocular axis of the  
range finder. Hence, the range finder should be thoroughly levelled  
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 reticle with a maximum  
accuracy of 0.05 mils.  
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).  
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.  
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 reticle with a maximum accuracy of 0.05 mils (small  
division value of the reticle is 0.05 mils, large division value is 0.10 mils).  
8.8. To convert the polar coordinates into rectangular coordinates,  
proceed as follows:  
-

10.6.1. To clean the contacts in the battery section, do the  
following:  
- remove the moist silica gel from the case and fill the case  
with the fresh one.  
Moist silica gel may be subjected to multiple recalculation at  
(120±3)˚ C without any deterioration of its properties. Using a  
microwave oven is allowed.  
- wind some cotton wool around one end of a wooden stick;  
- moisten the cotton wool with alcohol;  
- wipe the contacts several times by means of cotton wool  
moistened with alcohol.  
10.6.2. To remove dust and dirt from the optical surfaces, use the  
brush 23 and clean cloth 7 supplied in the individual SPTA set (see Fig.

following:  
To recalculate the silica gel, proceed as follows:  
- place the silica gel in a clean metal vessel;  
- place the vessel on the heat source providing heating up to  
(120±3)˚ C. Measure the temperature directly on the silica gel;  
- see the silica gel changing its colour.  
- wind some cotton wool around one end a wooden stick;  
- moisten the cotton wool with an alcohol and ether mixture  
(1:1) and gently shake the stick to remove excess mixture;  
- wipe the glass surface several times with the cotton wool,  
avoiding contact with the frame;  
The silica gel is dry and good for use when it turn bluish from  
pink. When heating up, keep the silica gel away from open flames.  
11. TROUBLE SHOOTING  
- change the cotton wool and move the stick end spiral style  
from the center towards the periphery to wipe the surface clean;  
- while cleaning, see that the mixture does not stain the frame,  
for it may dissolve the sealing mastic, causing leakage or ungluing of the  
lenses.  
10.6.3. The dehydrator case should be filled with fresh silica gel  
in a closed room. Under the field conditions, replace the silica gel when  
the weather is dry and calm. Never keep the case with fresh silica gel
