問題文
A survey report draws coverage well past the outer walls of the building and out over open ground. The reviewer suspects the propagation figure that the tool applies between recorded points. What is the cheapest way to deal with it?
選択肢
- Leave the figure alone and add points out of doors, because the reach beyond the walls has to be measured before it is drawn on a map.
- Lower the figure and then walk the whole floor again, because the points that were already recorded were sampled while the wider figure was in force.
- Raise the figure and redraw the points that were already recorded, because a wider figure holds the drawn signal inside the walls of the building.
- Lower the figure and redraw the points that were already recorded on the walk, because that setting may still be changed once the walk has finished.
