How to use a mechanical scale easily?
A mechanical level is a tool that craftsmen use when they are making a surface, such as a floor or wall. The level is used to determine how well the surface has been made.

How to use Tarazo?
- Clean the scale, removing all sediment and dirt from the edges.
- Mark a line on the wall along the bottom edge.
- Turn the scale over so that the top edge is where the bottom edge is. Place the new top edge along the marked line. If the scale is straight, your surface is accurate. If not, it is defective.
- Place the level on the surface of the object for which you want to adjust the correct horizon. Make sure that the level is parallel to the object.
- Align your eyes with the level of the scale. To read accurately, close one eye.
- Note where the vial is inside the scale. If it is centered between the pipe lines, your object is level. If the vial is to the right of the lines, your object is tilted down from right to left. If the tip is to the left of the lines, your object is tilted down from left to right.
