Connector X1 couples the controls and the Rechargeable battery to control circuit board (A1).
C1 and C2 are energy storage capacitors placed in the pumping circuit. They are charged up to
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
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
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
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.
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.
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.
