2.PURPOSE

2.1.Binoculars range finder LRB 20 000 AEP 36.28.001 is a device of industrial-technical purpose and designed for ground surveillance, observation of individual targets and measurement.

2.2.The range finder complete with the Angular Mount is designed for referencing ground location point by the predetermined landmark coordinates and is capable of:

- measuring horizontal angles and magnetic azimuths: - measuring vertical angles and angles of elevation;

- determination of target and landmark polar coordinates; - polar-to-rectangular landmark and target coordinate

conversion and determination of the OP and target coordinates from the predetermined landmark coordinates.

2.3.The range finder may find application in geological and engineering survey, repair works, maritime navigation, meteorology and tourism.

2.4.The range finder is operable in the temperature range between –40 and +50˚ C, relative air humidity of up to 98% (as taken at 35˚ C), air pressure of 61 kPa (460 mm Hg) minimum, and in the sea mist conditions.

2.5.Power to the range finder is supplied from rechargeable battery 10 D-0b55С-1. It may also be powered from a vehicle electrical system providing (27±2.7) V, or non-

rechargeable battery producing 12 to 14.5 or 22 to

29 V.
