  1. 1Balancing your levelling backsight and forsights will tend to eliminate which of the following problems?
    1. ACurvature and Refraction
    2. BInstrument Collimation
    3. CParallax
    4. DTotal Misclose
    5. EAutomatic Compensator Sticking
  2. 2The checks you must make when reducing your level fieldnotes are:
    1) calc'ing the sum of the [blank_start][a][blank_end] - the sum of the FS's,
    2) calc'ing the sum of the [blank_start][b][blank_end] - the sum of the [blank_start][c][blank_end],
    3) subtracting the [blank_start][d][blank_end] RL from the starting RL
    If all three numbers are identical (and same sign), you can adjust out the total misclose. This is done by spreading the adjustment out by dividing the misclose by the number of [blank_start][e][blank_end]. The sign of each individual adjustment (±) will be the [blank_start][f][blank_end] the sign of the total misclose.

  8. 8This is a diagram of a reciprocal levelling setup from your Uren and Price book. Using the following staff readings compute the RL of B given A has an RL of 50.000m. Show your answer in metres to 3dp and do not show any units.

    Staff readings @ I1 A = 0.456 B = 1.251

    Staff readings @ I2 B = 1.601 A = 0.781

  9. 9If the RL of TBM A is 20.005m and the staff reading to 'Y' is -2.967m, what is the RL of the underside of the bridge 'Y'? Show your answer in m to 3dp. Do not show any units.

  10. 10Pick the best word to complete the following sentence -

    An automatic level has a [blank_start][a][blank_end] as an integral part of the instrument. If the level telescope is tilted slightly, this mechanism uses a series of [blank_start][b][blank_end] to adjust the axis of [blank_start][d][blank_end] to remain along a [blank_start][e][blank_end] line.
