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, V1-
V2), 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.
