11. The unit of graduation on a horizontal-circle reading is _________________________________.A. 4 minutesB. 2 secondsC. 1 secondE. 0.1 second12. One method of reading the minute value of the horizontal circle uses both the upper <strong>and</strong> lowercircles. If both circles are used, the number of divisions or graduations from the degree mark on thelower circle to the degree mark diametrically opposite (180°) on the upper circle, when_____________________, gives the value of minutesA. Divided by 2B. Divided by 4C. Multiplied by 2D. Multiplied by 413. What is the least desirable type of traverse?A. An open traverse closed on a known pointB. An open traverseC. A closed traverseD. A closed traverse on a starting point14. When using a 1-second theodolite, what angular closure per station is expected?A. 1 secondB. 5 secondsC. 10 secondsD. 20 secondsEN0593 3-38
