Manual rangefinder LPR 1 repair diagram. Introduction. On the back and bottom sides

Position requirement

To conduct combat work, the decision maker is installed at the observation post in such a way that there is no interference in the beam line that would interfere with determining the coordinates of the selected targets.

Transfer LPR-1(2) from traveling to combat position in the following order:

Choose a place to observe;

If observations and measurements are to be made from a tripod, install the tripod in the chosen location by extending the telescopic legs to the required length and pointing one of the legs towards the observation, the base of the tripod should be approximately horizontal;

If there is no need or opportunity to use a tripod, unscrew the tripod cup from the base and secure it to some wooden object by inserting the anchor into the wooden object and screwing it there until it stops;

Install the angle measuring device with a ball support into the cup;

Level the ICD with a ball level by rotating the ICD in the cup and inserting the level bubble into the center of the ring marks. Securely fasten the ICD with a clamp;

Install the LPR-1 on the angle-measuring device, moving the rangefinder along the guides of the ICD bracket, insert the ICD clamp into the TV-shaped groove of the rangefinder bracket until it stops, then securely fasten the rangefinder by turning the handle of the clamping device;

Orient the rangefinder along the magnetic meridian.

When working with a periscope artillery compass, transfer the device from the traveling position to the combat position in the following order:

Install the compass tripod, place the compass in the tripod cup, level it and orient it;

Install the adapter bracket on the compass monocular and securely secure it with the clamp screw;

Moving the rangefinder along the guides of the adapter bracket, insert the bracket clamp into the T-shaped groove of the rangefinder bracket until it stops, then securely fasten the rangefinder by turning the handle of the adapter bracket.

Transfer the device from the combat position to the traveling position in the following order:

Turn the handle of the clamping device of the ICD or adapter bracket all the way and remove the rangefinder from the ICD or adapter bracket, put it in the case;

Also put in the case, a coordinate converter, a napkin, a pencil, an eraser, and a spare battery (if they were used in the work).

Application of the device

Turn the switch to the ON position;

Point the rangefinder at the target;

Press the “Measurement 1” button and release it after the readiness indicator lights up;

Take the range reading and elevation angle of the target, i.e. polar coordinates;

When the red indicator lights up, replace the battery;

If there are several targets in the goniometric grid gap during measurement, the decimal point in the low-order digit of the range indicator lights up.

By pressing the “Measurement 1” and “Measurement 2” buttons, you can measure the distance to the first and second targets;

If there is a measurement, for example, through bushes, it is necessary to set the minimum range limit with the handle, rather than a distance slightly greater than the distance to the bushes and carry out the measurement. In this case, the beam reflected from the bushes will not be detected, that is, we will get the distance to the target;

When working at night, switch the “Backlight” switch to the ON position.

V. Start processing mode.

1. Move the platform to the Home point position by pressing the button on the program control panel.

2. Turn on the Power unit by turning the key on this unit to the horizontal position.

3.Wait for the unit to enter operating mode and press the reset button on the BKU 4-2 control panel. (Perform until the processing mode parameters are displayed on the display).

The purpose of the rangefinder blocks and assemblies is the same as the corresponding blocks and assemblies of the DAK-2M transceiver.

Main controls of LPR-1 (Fig20).
On the front and top sides:

Cover with battery compartment handle;

Toggle switch "OFF" - "ON" to turn the device on and off;

Drum (handle) “STROBING” - to set the minimum range, closer than which range measurement is impossible;

Visor eyepiece;

Indicator eyepiece;

Toggle switch "ON" - "OFF" - to turn on and off the illumination of the reticle of the reticle;

- buttons “MEASUREMENT 1” and “MEASUREMENT 2” - to measure the range to the first or second target located in the radiation target.

Rice. 21. Field of view of the LPR-1 indicator

1-range indicator; 2,5,6-dicimal points; 3-ready indicator (green); 4-battery discharge indicator (red).

If there are several targets in the radiation target (at a break in the goniometric grid) during measurement, the decimal point in the least significant digit of the range indicator lights up (Fig. 21. position 2).

If it is impossible to remove screening interference beyond the gap in the goniometer grid, as well as in cases where interference is not observed, and the decimal point in the low (right) digit of the range indicator is lit, point the rangefinder at the target so that the target covers, possibly, a larger area of ​​the gap goniometric grid. Measure the range, then set the minimum range limit knob to a range value that exceeds the measured value by 50-100 meters and measure the range again. Repeat these steps until the decimal point in the most significant digit goes out.

When zeros are displayed in all digits of the range indicator and the decimal point is illuminated in the most significant digit (left) (Fig. 21. position 6) of the indicator, it is necessary to turn the minimum range limit knob to reduce the minimum measured range until a reliable measurement result is obtained.
