Azimuth Screw
From the previous page we have the value of one revolution of the azimuth screw as equal to 5.345 +- 0.008 intervals of the transit reticule. Now the value of one interval of the transit reticule has been found to be 5[superscript]?s or d?[/superscript].42 [See page 29] Using this value for the transit interval we find one revolution of the azimuth screw is equal to 28[superscript]?s or d?[/superscript].979 +- 0[superscript]?s or d?[/superscript].09 = 7' 14".685 +- 0".8 arc.
See page 11 for explanation.
