Main ideas / lessons

  • The video continues a Grade 11 unit on digital mapping and measurement, focusing on how to set up and adjust a digital theodolite before measuring.
  • Proper setup includes:
    1. Erecting and placing the tripod/theodolite correctly over the survey station.
    2. Centering the theodolite so its line of sight aligns with the benchmark point.
    3. Balancing/leveling the instrument using the Nivo (bubble level) so measurements are accurate.
    4. Re-checking centering and leveling repeatedly until the instrument is confirmed correct.
  • Once these conditions are met, the digital theodolite is ready to measure angles and distances.
  • The session concludes with motivation to keep learning and to follow health protocols.

Step-by-step methodology (digital theodolite setup before use)

1) Erect the tripod

  • Place/erect the tripod above the surveying (measuring) point/station.
  • Unlock the tripod legs and adjust the tripod height to match measurement needs.
  • Ensure the tripod plate is flat to make later setup easier.

2) Position/center the tripod over the station

  • Check that the tripod is exactly above the measuring point.
  • Verification methods mentioned include:
    • Viewing alignment relative to the station using binoculars (“santri binoculars”).
    • Dropping a pebble from the station/benchmark point and checking whether it lands on the peg/nail (the correct target).
  • The benchmark should typically be visible through the binocular view.

3) Install the theodolite on the tripod

  • Carefully mount the theodolite onto the tripod.
  • Use proper handling:
    • One hand locks the instrument position on the tripod.
    • The other hand holds the handle to prevent it from falling during installation.

4) Optically center the theodolite

  • Check centering through the telescope/binocular optical view.
  • If centering is not correct, correct it using the ABC screw (adjustment screws).

5) Level/balance the instrument with the Nivo (bubble level)

  • Adjust until the Nivo bubble is centered (middle of the scale circle).
  • If not balanced, adjust tripod leg height/length until the bubble is correct.

6) Balance the Nivo in four positions using ABC screws

  • After balancing at one orientation, continue systematically in four positions:
    • Position 1: Nivo tube parallel to 10ab → balance by turning screw AB.
    • Position 2: Nivo tube perpendicular to the reference line → balance by turning screw C.
    • Position 3: Nivo tube back parallel to 1.bab → balance by turning screw AB.
    • Position 4: Nivo tube perpendicular again → balance by turning screw C.
  • Then turn the theodolite back to position 1 and check whether the Nivo remains balanced.
  • If the bubble shifts, repeat the balancing procedure.

7) Re-check centering

  • After leveling, verify centering again.
  • If centering has shifted:
    • Loosen the theodolite position lock on the tripod,
    • Shift the theodolite while observing the centering through the telescope,
    • Re-tighten to restore correct centering.

8) Re-check Nivo level (bubble)

  • Check the Nivo tube again after centering corrections.
  • If it shifted, re-balance the Nivo again (repeat the method from step 6).
  • The subtitle emphasizes repeating steps 6 and 7 until:
    • Centering is correct, and
    • The Nivo is consistently balanced, indicating the instrument is correct on the correct point.

9) Measure and record the instrument height

  • Use a hair kurato meter (as written) to measure the height of the instrument/measuring tool.
  • Record the height in the field/tally sheet (“talisit”).
  • This height is needed for calculations such as exact height or height difference between points.

10) Finish setup

  • Once the steps are complete, put the tool down appropriately and proceed to the next stage of measurement activities (the next topic is referenced as “glucose elkisi,” likely continuing the procedure).
