Metal ruler is the most basic and important measuring tool used by decoration workers. In addition, metal rulers are also used in other fields, such as designers to draw drawings to use metal rulers, students in the learning process will also use metal rulers, carpenters in the production of furniture will also use metal rulers and so on.
Correct operation method of metal ruler:
Before using the metal ruler, it is necessary to check whether the edge of the metal ruler and the scale line are intact and accurate, and to ensure that the surface of the steel ruler and the object to be measured is clean and smooth, and can not be bent and deformed.
In the metal ruler measurement, the zero scale to be selected coincides with the starting point of the measured object, and the metal ruler is close to the measured object, which can increase the measurement accuracy.
It is also possible to turn the ruler 180 degrees and measure it again, and then take the average of the two measured results, so that the deviation of the metal ruler itself can be eliminated.
Precautions when use te metal rulers:
1. Before the use of metal ruler, we should first check the metal ruler parts for damage, do not allow the appearance of defects affecting the use of performance, such as bending, scratches, scale broken line or can not see the scale line defects.
2. The metal ruler with suspension holes must be wiped clean with clean cotton silk after use, and then suspended to make it naturally droop. If there is no suspension hole, the steel ruler is wiped flat on the flat plate, platform or flat ruler to prevent its compression deformation;
3. If not used for a long time, the metal ruler should be coated with anti-rust oil storage location should choose low temperature, low humidity location.
