How to use the reticle and calculator dial as measuring devices

The reticule has horizontal scale and vertical scale, in the below there is measuring reticle according to the known height .see Fig 7.

vertical and horizontal lines on the reticule is in mils as unit. Each small division on both vertical and horizontal lines represents 5 mils and each big division represents 10 mils. You can obtain the azimuth angle, upper and lower angle, distance and height or width etc. by using this reticle. The fast distance measurement is regards as the target as 2 metre high to measure the distance quickly.

How to measure the Horizontal View Angle
The azimuth angles is the angle included between two objects to be measured at the horizontal direction of the binocular. When the Horizontal View Angle is smaller than the horizontal scale range (-40 ～ +40 mils) inside the binoculars, aim one edge of the object at a horizontal scale line(the center or the outmost line are selected according to the image size of object usually) and read its value. Then read the value of the scale at which another edge was located. Plus this two value, the sum value is the measured Horizontal View Angle. As shown in Fig 8, the Horizontal View Angle of the target (tank) is 20-00 mils, the Horizontal View Angle is 20 mils.

When the Horizontal View Angle is bigger than the horizontal scale range (-40~+40 mils), an vertical line splits(for example: podium of the cruiser) on the object can be selected to make the necessary estimated measurements in a step by step fashion. The sum of the value from each step is used to obtain the measured value. As shown in Fig 9, the azimuth of target (cruiser) is 110 mils (60+50=110).

How to measure the Vertical View Angle
Upper and lower angle means the angel included between any two targets (or two ends of the target) against the vertical line on the reticle. Vertical View Angle measurement is similar to measuring the Horizontal View Angle. When the Vertical View Angle measurement is small, aim the cross center of reticle at lower part of the object, read the scale value at the top of the object. If the target vertical angle is a little bigger, you can read the upper scale and the lower scale, As shown in Fig10, the upper line is 35mils, and the lower line is 40mils,the total vertical angle is 75mils.(35+40=75) Fig 10

when the Vertical View Angle is larger than the vertical scale range, it can be measured in steps and the angle can be obtained by summing up the value of each step. (The process will be similar to the measurements as mentioned above as horizontal view angle.)

How to use the reticule to measure distance
The distance measurement of a target can be calculated by using the mil reticule.

The formula of distance measurement: L（km）= H (m)/ω

• L — the distance between the observer and the object (km)
• H — the height of the object (m)
• ω— the View angle of the object measured with the reticule of binoculars (mil). When measure the distance, first, estimate the width or height of the object, then measure the View Angle of the object. According, you can calculate the distance between the observer and the object using the formula.

For example 1:
There is an lighthouse height is 25m. (H = 25m)
The Vertical View Angle of the adult is 6 decade mils (60mils)
L = H/ω = 25/60 = 0.4166km = 416.6m
Therefore: the distance between the observer and the adult is 416.6m.

For example 2:

There is an adult whose height is 1.70m. (H = 1.70m)
The Vertical View Angle of the adult is 4 decade mils (40mils)
L = H/ω = 1.7/40 = 0.0425km = 42.5m
Therefore: the distance between the observer and the adult is 42.5m.

How to measure a object’s size (height and width) using
According to the formula for distance measurement, you can calculate the height using: H = L × ω.
When measuring the size, you first estimate the distance to the object, then measure the View Angle. With these measurements, you can calculate the height of the target using the formula.

For example:
the distance is 0.6km between the observer and the object. You can measure that the Horizontal View Angle is 6 decade mils(60mils) and the Vertical View Angle is 3 decade(30mils). So, using the formula you can get:
The height: H = 0.6 × 30 = 18m
The width: h=0.6 × 60=36m

Quick distance measurement:
The reticle is consisted of one horizontal line and a diagonal line. And regards the H=2m as known height to quickly measure the common target such as vehicle or adult. Placing the target projection between the 2 lines, The reading on the tangency of the projection and diagonal line is the target distance (line value:100m). as shown in Fig.12, the distance between the target in 2m high and the observer is 550m.

How to measure the Horizontal View Angle
The azimuth angles is the angle included between two objects to be measured at the horizontal direction of the binocular.

• When the Horizontal View Angle is smaller than the horizontal scale range (-4～+4 mils) inside the binoculars, aim one edge of the object at a horizontal scale line(the center or the outmost line are selected according to the image size of object usually) and read its value. Then read the value of the scale at which another edge was located. Plus this two value, the sum value is the measured Horizontal View Angle. As shown in Fig 16, the Horizontal View Angle of the target (tank) is (-2～+2 mils), and the Horizontal View Angle is 4 mils. See

• When the Horizontal View Angle is bigger than the horizontal scale range (-4~+4 mils), an vertical line splits on the object can be selected to make the necessary estimated measurements in a step by step fashion. The sum of the value from each step is used to obtain the measured value. As shown in fig 17, the azimuth of target (cruiser) is 13 mils (6+7=13).

How to measure the Vertical View Angle
Upper and lower angle means the angel included between any two targets (or two ends of the target) against the vertical line on the reticle.

• Vertical View Angle measurement is similar to measuring the Horizontal View Angle. When the Vertical View Angle measurement is small, aim the cross center of reticule at lower part of the object, read the scale value at the top of the object. As shown in Fig 18, the angle included between the upper and lower parts of the target is 6 mils.

• when the Vertical View Angle is larger than the vertical scale range (8 mils), it can be measured in steps and the angle can be obtained by summing up the value of each step. (The process will be similar to the measurements as mentioned above as horizontal view angle.)

How to use the reticule to measure distance
The distance measurement of a target can be calculated by using the mil reticule.

The formula of distance measurement: L（m）≈100*H/K

• L — the distance between the observer and the object (m)
• H — the height of the object (m)
• ω— the View angle of the object measured with the reticule of binoculars (mil). When measure the distance, first, estimate the width or height of the object, then measure the View Angle of the object. According, you can calculate the distance between the observer and the object using the formula.

For example 1:
There is an lighthouse height is 25m. (H = 25m)
The Vertical View Angle of the adult is 6 mils
L ≈100H/ω = 10025/6= 2500/6 = 416.6m
Therefore: the distance between the observer and the adult is 416.6m. For example 2:
There is an adult whose height is 1.70m. The Vertical View Angle of the adult is 4 mils L ≈100H/ω= 1001.7/4= 170/4 = 42.5m
Therefore: the distance between the observer and the adult is 42.5m.

How to measure a object’s size (height and width) using
According to the formula for distance measurement, you can calculate the height using: H ≈ L × ω/100.
When measuring the size, you first estimate the distance to the object, then measure the View Angle. With these measurements, you can calculate the height of the target using the formula.

For example:
the distance is 600m between the observer and the object. You can measure that the Horizontal View Angle is 6mils. and the Vertical View Angle is 3mils. So, using the formula you can get:
The height: H≈ 600 × 3/100 = 18m
The width: h≈600 × 6/100=36m

How to use the compass

The azimuth angle can be measured through the compass built into the right half of the body . It shows the azimuth of the object relative to the observer. Each graduation of the compass equals one degree of angle. When the object lies in the north from you, the compass shows 0(degree) .And it will increase when you turn clockwise. 90 °means the object lies in the east from you, 180°means the south and 270°means the west.

In order to insure precise angle measurements, Be away from the ferromagnetism material during the working condition. (such as cannon, tanks, battle vehicle, high voltage, transformer substation, ferromagnetic mill, electric & ferromagnetic appliance),otherwise the compass will work in big error or improperly. And the binoculars should be kept horizontal and level when reading the compass. The upper and lower angle can not be over ±15 °.The object should lie in the middle of the reticule. The graduations of the compass need to be illuminated for convenient viewing when there is not sufficient daylight to illuminate the compass dial. Press the illuminator button, the compass scale will be illuminated in red light for easy viewing.
