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
542.
Which of the following situations
requires the use of the vertical
cross hair?

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
544.
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 engineers 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.
