5–39. You  are  adjusting  the  telescope level on a transit. When you complete  this  adjustment,  what  is your  next  step? 1. Check  the  plate  bubbles 2. Recheck the telescope level 3. Check  the  vertical  vernier 4. Begin  the  survey 5-40. When the plate bubbles are properly aligned on a transit, this will ensure  what  condition? 1. Horizontal angles are measured in  a  true  horizontal  plane 2. Vertical angles are measured in an  inclined  plane 3. Index error is very small 4. Plate  level  tubes  are  parallel to the vertical axis 5-41. What test should be performed every time you set up a transit? 1. Telescope  level 2. Line of site 3. Plate  bubbles 4. Vertical  circle  vernier 5–42. Which of the following situations requires the use of the vertical cross  hair? 1. To lay out a fence line 2. To lay out utility poles 3. To lay out a building 90° to another  building 4. Each of the above 5-43. If the line of sight is maladjusted in a transit, how do you compensate for it in the field? 1. By  double  centering 2. By  turning  multiple  angles 3. By rotating the cross hairs 5–44. When you are using a transit for direct  leveling  and  the  telescope level is out of adjustment, what is the  correct  method  of  compensating? 1. Same  as  the  engineer’s  level 2. Repair  it  before  use 3. Ignore it as it has no effect 5-45. To compensate for a misaligned vertical vernier, you should 1. read  all  vertical  angles reversed only 2. read  all  angles  horizontal  only 3. read  all  vertical  angles  direct only 4. read  all  vertical  angles  direct and reversed and then use the average 5-46. The EA should make minor and major repairs to all equipment. 1. True 2. False 5-47. Equipment in need of adjustment should be adjusted at what interval? 1. Monthly 2. Weekly 3. Every 2 weeks 4. Whenever it is needed 5-48. Which of the following activities may perform minor repairs? 1. Navy cal lab 2. Local PWD 3. Battalion  machine  shop 4. Each of the above Learning Objective: Identify where to  find  information  regarding surveying  equipment  and  supply requirements  for  a  battalion. 5-49. When a piece of equipment is damaged  beyond  repair,  it  must  be replaced. You may obtain a replacement  from  what  source? 1. PWD 2. Equipment   manufacturer 3. Army/Navy  surplus  store 4. Navy supply system 4. Replace  the  telescope 32
