azimuth scale वाक्य

The theodolite is typically mounted on a rugged steel stand, set up so it is level and pointed north, with the altitude and azimuth scales reading zero degrees.
The collimator can be traversed in a full circle, and the azimuth scale is calibrated in 100-mil graduations in two sections of 3, 200 mils each.
Next, another radial arm, called the "'gun arm "', was swung over the plotted position of the target, and the resulting range and azimuth for firing were read off the gun arm and an azimuth scale on the gun arm center.
Each of the two arm setters at the board moved his assigned arm ( the primary or auxiliary arm ) to the position on the notched azimuth scale ( which ran around the circumference of the board ) that corresponded to the azimuth reading ( in whole degrees ) he had just received by phone from his base end station.
To locate a target, plotting board operators used two radial arms ( called the "'primary "'and "'auxiliary "'arms ), and " locked-in " the ends of these arms along on the notched azimuth scale that ran around the circumference of the board at the azimuths of the sightings that were telephoned in to them by the two base end stations.
