The  instrumentman  is  moving  his 9-2. 9-3. 9-4. right  arm,   which is extended upward, to the right.    What  message is he signaling to the rodman? 1. The rodman must move the rod to the right 2. The rodman must move the top of the rod to the right until it is  vertical 3. The rodman must move the rod to the left 4. The rodman must move the top of the rod to the left until it is vertical An instrumentman extends both arms upward,    what  does  this  indicate  to the  rodman? 1. Move forward 2. Reverse the rod 3. Pick  up  the  instrument 4. Face the rod What actions should the rodman take in  response  to  a  boost-the-rod signal? 1. 2. 3. 4. The out and Raise the rod and hold it at a specified  distance  above  the ground Turn the rod upside down Raise the rod slowly until the instrumentman  has  read  the whole-foot  mark Move the top of the rod, in a short  arc,    towards  the instrument instrumentman  extends  both  arms horizontally  from  his  shoulders waves them up and down. What message is he giving to the rodman? 1. Come in 2. Pick  up  the  instrument 3. All  right 4. Move forward 9-5. 9-6. 9-7. 9-8. In  clearing  a  chaining  line,  what should you do when a valuable tree lies directly in your path? 1. Triangulate  around  it 2. Find the owner and request the tree to cut down 3. Cut it down 4. Choose a different chaining line What term is used to describe consecutive  sights  taken  through  a telescope for the purpose of keeping  chainmen  on  line? 1. Running  line 2. Bench  mark 3. Foresight 4. Backsight When  an  instrumentman  takes  a  sight along a portion of a line that has already been run, he is taking a 1. horizontal control step 2. vertical  control  step 3. foresight 4. backsight For  what  reason  should  a  chainman use an indicator that is narrower than a range pole when holding on or plumbing over a point for short sights? 1. 2. 3. 4. To  enable  the  instrumentman  to align the indicator exactly with the vertical cross hair of his  instrument To  enable  the  instrument  to sight beyond the point To  enable  the  chainman  to  carry out  his  duties  without  becoming fatigued To enable the chainman to hold the  indicator  steady 58
