of the object
10-68.
Which of the following situations
is considered a mistake in transit
work?
1.
Failure to record the
direction in which an angle
was turned
2.
Turning a deflection angle in
the wrong direction

10-69.
The carrying case for a transit or
a theodolite is specifically
designed for which of the
following conditions?
1.
To protect the instrument from
extreme temperatures
2.
To serve as a part of the
instrument when it is set up
for use in the field
3.
To prevent excess motion when
the instrument is being
carried
4.
All of the above
10-70.
Which of the following actions
should you take after an
instrument has been exposed to
rain and has been wiped down with
a clean cloth or chamois leather?
1.
Dry it in a heated room
2.
Stow it right away in its case
3.
Dry it thoroughly at ordinary

10-71.
What is the recommended lubricant
for surveying instruments at
sub-zero temperatures?
1.
Oil
2.
Water
3.

4.
Graphite
10-72.
Which of the following statements
describes the characteristics of
an open traverse as compared to a
closed connecting traverse?
1.
An open traverse has only one
previously determined end
point, but a closed connecting
traverse has two
2.
Both types of traverses may
not be used for preliminary
surveys
3.
An open traverse is open at
both ends, but a closed
connecting traverse forms a
loop so that the ends are
closed
4.
A closed traverse provides
fewer checks against error
than an open traverse
10-73.

2.
Only the forward station is
visible from any station
3.
Both stations are visible from
any one station and the
maximum number of instrument
setups can be kept
4.
Both stations are visible from
any one station and the number
of instrument setups can be
kept to a minimum
10-74.
In double taping between traverse
stations, you should use which of
the following procedures?
1.
Use only tapes that are
calibrated
2.
Ensure the stations are spaced
so that the distance between
stations is less than a
full-tape length
3.
Continue taping until the
tie-in control point is
reached; then retape all
measurements
4.
Retape line measurements not
within allowable limits
10-75.
