[How to make the FINDER]
1. Copy this page (about A4 size).
2. Attach the copy on the same size paperboard.
* Make sure to align the ground connection side below with the edge of
the paperboard. (Jog)
3. Get prepared for the string (about 27cm = 10.6 inches)
4. Make a pin hole at the O part on the upper right corner.
* Put the string through the hole and tape it up.
5. Attach a perforated coin (e.g., 5 centavo coin) to the other side of the
string.
Done and Ready to measure RAMP GRADIENT!
[How to measure the RAMP GRADIENT]
1. Put the ground connection side on the ramp surface.
2. Perceive the string location at the area of gradient criteria (1/20,
1/12)
- When the string is located at the BLUE area, it complies with a criterion
of 1/20.
- When the string is located at the GREEN area, it complies with a
criterion of 1/12.
- When the string is located at the left area (left-leaning), the ramp
gradient is steeper than the criteria.
