Topcon ES 65 Total Station Survey and Layout | ES series | Survey Nepal

Main Ideas, Concepts, and Lessons

The video demonstrates how to perform surveying tasks—specifically setting out/layout and measuring (including backside work)—using a Topcon ES series total station, with focus on the ES65 model.

It walks through:

1. Device overview and key features (adjustment screws, ports, optical plummet, display, and shortcut keys)
2. Power-on and leveling / electronic bubble adjustment
3. Angle setup and calibration (zero-setting, angle holding, tilt/environment options, and laser targeting)
4. Switching measurement modes (coordinate/distance/angle) and using measurement, including non-prism measurement
5. Creating and managing survey jobs/files and setting station parameters
6. Backsight and traverse-style point recording (entering point numbers/codes/types, measuring, and tolerance checks)
7. Setting out (layout) workflow using client/design coordinates and previously recorded points
8. Data management and file transfer (memory manager, and cable/USB options)

Methodology: Step-by-Step Workflow

A) Tool Setup and Device Introduction (ES65 Features)

Identify key controls and components:

• Vertical screw and slow-motion vertical control
• Horizontal tangential screw and slow-motion horizontal control
• Battery adapter
• Port for data downloading (USB option mentioned)
• Optical plummet
• Measuring key
• Shortcut keys
• Single display interface

B) Power On and Leveling / Bubble Adjustment

1. Power on the instrument.
2. Check leveling status:
   • Only the lower base circular bubble is active/visible (the upper plate bubble is not present).
3. Open the electronic bubble / leveling screen.
4. Adjust leveling so X/Y values are as small as possible.

Goal: proper leveling for accurate measurements.

C) Angle Initialization and Basic Calibration

1. View vertical and horizontal angles on the display.
2. Use Zero Set to set the current direction as 0°
   • Note: some fluctuation may occur due to an unstable tripod.
3. Use Horizontal angle hold / set:
   • Press S (hold)
   • Use Set to input a required horizontal angle (example: 60°).
4. Explore additional configuration pages/options, including:
   • Tilt and other instrument configuration pages
   • Reflector/prism vs non-prism options (including references like “seat”)
   • Illumination settings for keys/display
   • Contrast / vertical illumination
   • Laser target power (laser on/off through the relevant key/page)

D) Measurement Mode Switching (Distance vs Coordinate vs Angle)

1. Open Coordinate/Distance related options.
2. Enter distance mode.
   • Press measure to measure horizontal distance and/or slope distance.
3. Demonstrate measurement using the through non-prism option.
4. Return to the required angle/normal mode when needed.

E) Job/File Creation and Station Setup

1. Open Menu.
2. Create/select a new job (file).
3. Example: create a file/job named “nepal.”
4. Go to station setup:
   • Set point/station number (example: Point 1, station label STN)
   • Enter instrument/station parameters (example value shown: 1.45)
5. Verify/edit any required station-related recorded values.
6. Confirm/record the setup.

---

F) Backsight Setup and Tolerance Validation

1. Insert a backsight point:
   • Use insert (example: Point 2)
   • Assign a point code (example: BM)
   • Set reflector height (example: 1.30 m)
2. Determine backsight orientation:
   • Use angle alignment (turn to north/zero) or
   • Use coordinate-based backside input (based on what’s known)
3. Measure the backsight:
   • Press measure to obtain the reading.
4. Check tolerance:
   • If within tolerance, press S to accept.
   • If not, press escape/back (optionally “no”), re-enter values, and measure again.
5. Mark the backsight as completed.
6. Use Backside (F3) / advance workflow to proceed to subsequent points.

G) Recording Points for Layout / Traverse Data

1. Measure the next points (example: Point 3, then it increments automatically).
2. Enter point code/type (example: pole).
3. For each point:
   • Measure with the instrument
   • Record the coordinate result shown on screen
4. Demonstrate point type formatting changes:
   • Example includes clearing and entering a type string like “wall”.

---

H) Setting Out / Layout (Using Client Design Coordinates)

1. Go to Layout (example function: F3).
2. Ensure prerequisite:
   • Station setup must be connected to a previously set station
   • Select the station from the saved list (or set it up if needed)
3. Enter the design/client coordinates.
4. Orient the instrument to the required angle (example: 21°48’).
5. Advance to the required distance ahead using instrument guidance, then move to the stakeout location.
6. Use stored layout point data:
   • Select a stored point to view the needed distance and angle
7. Example approach to reach a target point:
   • Set angle to a tentative value (example: 20°10’)
   • Measure to a tentative distance with a tape
   • Refine until the measured position matches the required point
8. Repeat the workflow for additional points.

I) Data Management and File Transfer

• Use Memory Manager to check:
  • File status
  • Total measured/coordinate data for the current station
• Use page navigation:
  • Page 3 includes file transfer options
  • Transfer can be done via cable or USB
• Download/export is shown as a topic for a subsequent video.
