How to use the high-precision level meter

The use of high precision level meter mainly includes the following steps:

Preparation: Before using the high-precision level meter, first of all, make sure that the measurement environment is stable and avoid using it in a windy place, because the wind will make the ground produce tiny fluctuations and affect the measurement results. Make sure the base of the level meter is smooth and reliable to ensure the accuracy of the measurement.

Placing the level: Place the level on one end of the object to be measured so that the centerline of the level is aligned with the edge of the object to be measured. If it is a flat surface, you can place the level on the edge; if it is a curved surface, you can place the level on one side of the surface.

Adjusting the level: Adjust the height of the level so that it remains parallel to the object to be measured. For an electronic level, simply adjust the dial to align with the object to be measured; for a traditional level, you need to manually adjust the dial to keep it parallel to the object to be measured and make sure the level bubble is located on the center scale.

Read the measurement result: for electronic level meter, directly observe the value on the LED display; for traditional level meter, you need to rotate the dial to find the scale line aligned with the object to be measured, and then read the value on the scale line. After reading the value, it is necessary to check again whether the level meter is parallel to the object to be measured to ensure the accuracy of the measurement results.

Calibration method of high precision level meter:

Preparation: Before calibration, make sure the surface of the level meter is flat and without obvious damage. It is also important that the environment is dry and ventilated, as water vapor may shift the position of the bubbles.

Setting the reference point: find a stable and firm place as the reference point, overlap the center line of the bubble tube and the reference plane, put it on the stable surface and wait for the bubble to stabilize, and write down the reading as the reference point. Note that when choosing the reference point, make sure that the point is completely horizontal or vertical.

Calibrate the horizontal direction: Adjust the instrument so that the bubble is in the center of the standard line. In the process of adjustment, the movement should be gentle to avoid excessive force causing the instrument to shake, which will affect the position of the bubble judgment.

Calibrate the vertical direction: rotate the level meter 180 degrees and calibrate again, so that the bubble returns to the center of the standard line. Be careful to keep the level meter stable during this process, don't let it tilt or move.
