To quickly assess the difficulty of the text, read a short excerpt:
In securing the scale to the platen the zero range graduation must coincide with the reference line.
7. Attached to the platen is the 15-second platen scale. This scale represents the angular travel of the target in azimuth during 15 seconds, and the graduations are to the same scale as those on the deflecticix and azimuth correction scales. The numbers run from left to right, the reference number at the origin (median line of platen) being 15°, to correspond to the azimuth correction scale of ...the plotting board. The maximum reading allows for a setting of 5° either to the right or to the left. This corresponds to a speed of the target of about 12 miles (10 knots) per hour at 1,000 yards range, or 24 miles (20 knots) per hour at 2,000 yards, etc. The right edge of the travel arm of boards Nos. 1 to 139, inclusive, but the left edge of boards after No. 139, is the fiducial edge: the other edge is scal- Digitized by VjOOQIC 10 loped to prevent the taking of reading from that side. The purpose of this scale is to correct for travel of the target during the time of flight of the projectile.
