Setting up a stadiometer typically involves mounting it securely against a wall, ensuring the measuring tape is correctly aligned, and verifying the accuracy of the initial measurement. Here's a step-by-step guide:
1. Preparation and Placement:
- Select a suitable location: Choose a flat, vertical wall that is free from obstructions. The floor area should be level.
- Gather necessary tools: You'll need a pencil, a level, a measuring tape (if the stadiometer doesn't have one built-in for mounting), a drill, and appropriate screws or mounting hardware for your wall type (e.g., drywall anchors, screws for wood studs).
- Unpack the stadiometer: Carefully remove all components from the packaging and inspect them for any damage.
2. Mounting the Stadiometer:
- Position the base: Place the base of the stadiometer on the floor, flush against the wall. Have someone hold it steady.
- Align the measuring tape: Extend the measuring tape (if it's a pull-up style) upwards. Ensure the zero point aligns correctly with the base. This alignment is crucial for accurate measurements. Some stadiometers require you to manually position and secure the tape measure to start at zero at the base.
- Mark screw holes: Using a pencil, mark the locations of the screw holes on the wall through the mounting brackets on the stadiometer. It may be helpful to use a level to ensure the stadiometer is perfectly vertical before marking the holes.
- Drill pilot holes: Carefully drill pilot holes at the marked locations. Use a drill bit appropriate for your wall type. If drilling into drywall, consider using drywall anchors for added stability.
- Secure the stadiometer: Align the stadiometer with the pilot holes and use screws to securely fasten it to the wall. Tighten the screws until the stadiometer is firmly in place but avoid over-tightening, which could damage the wall or the stadiometer.
3. Verification and Calibration (If Necessary):
- Check alignment: Use a level to ensure the stadiometer is perfectly vertical.
- Verify zero point: Double-check that the zero point on the measuring tape aligns with the floor.
- Test measurement: Have someone of known height stand against the stadiometer to verify its accuracy. Adjust if needed. Some stadiometers have calibration adjustments.
Example:
Let's say you're installing a Seca 213 portable stadiometer. This type often has a pull-up measuring tape. You would first position the base. Then, you'd extend the measuring tape upwards, making sure "0" lines up at the base. Mark the wall, drill, and secure as described above.
Troubleshooting:
- Inaccurate readings: Double-check the zero point and ensure the stadiometer is perfectly vertical.
- Wobbly stadiometer: Ensure the mounting screws are tightened securely and that you're using appropriate wall anchors if needed.
By following these steps, you can properly set up a stadiometer for accurate and reliable height measurements.
