How to calibrate the horizontal ruler? Do you need to calibrate the ruler every time
1, What is a ruler
A measuring tool, mainly used to measure the verticality of walls, wall flatness, ground flatness, levelness or slope, has four types: student ruler, vertical detection ruler, diameter measuring ruler, and engineering quality detector. It is a type of horizontal ruler and is widely used in construction and decoration projects.
2, How to calibrate a horizontal ruler
The range of use of a ruler is wide, and it is often used. However, if the ruler is not accurate, it will affect the measurement effect and construction. Therefore, if the ruler is found to be inaccurate and needs to be corrected, how can the ruler be corrected?
When testing, if a deviation is found in the pointer value of the guiding ruler, the guiding ruler to be corrected should be placed on the standard for calibration and adjustment. The standard can be self-made. A horizontal straight wooden or aluminum profile with a length of about 2.2 meters should be installed on the wall, and adjusted vertically by a plumb line. The guiding ruler should be placed on the standard horizontal object, and the "S" screw of the leveling tube should be adjusted with a cross screwdriver to center the bubble.
3, Do we need to calibrate the ruler every time
In actual measurement, the accuracy of the guiding ruler is very important. If an inaccurate guiding ruler is used, it will cause great trouble and loss to the construction. Therefore, it is necessary to calibrate the guiding ruler regularly. So, should the guiding ruler be calibrated every time it is used?
According to the calibration specifications for guiding rulers, they need to be calibrated after a period of use. The specific usage time varies depending on the frequency of use. Frequently used guiding rulers usually need to be calibrated every two to three days. Strictly speaking, calibration is required every time they are used, but in reality, calibration can be troublesome every time they are used, so this is usually not done.
Additionally, it should be noted that when choosing a guiding ruler, it is advisable to choose one with higher accuracy. New guiding rulers have higher accuracy and do not require frequent calibration. If used for a long time, regular calibration is necessary; Also, if a guiding ruler has not been used for a long time, before using it again, it should be measured for accuracy. If it is not accurate, it must be calibrated before use.
