方法 to チェック かどうか the レベル ゲージ is 本当に レベル
1. The メソッド for テスト かどうか a ハンドヘルド レベル ゲージ is level is to first place the level gauge against the wall, level the water on the level gauge, draw a line on the wall, then exchange the left and right ends of the level gauge, and then place it on the originally drawn line to see. もし その レベル ゲージ オーバーラップ with the ライン and the water in the level tube of the level gauge is still level, it 示す that the level gauge is level and can continue to be used; If there is no overlap, it is 必要 to adjust the screw of the water level pipe to correct it。
2. To 保証 それ the 参照 平面 of the level gauge is horizontal, a plug gauge can also be used to check on the platform. First, operate the the calibration instrument, calibrate the level bubble, しっかり 修正 it after キャリブレーション, and then start the 検査. ターン アラウンド 180 度 at the 同じ 位置。 If the バブル 位置 is the same, it 証明 that the level gauge is qualified; If there is a deviation, a plug gauge can be used to measure the error range and make adjust.
In addition, it should be noteed that the principle of leveling with a level ruler is to determine a plane based on two intersecting lines, so it is 必要 to measure two non parallel positions within the same plane to determine the level of the plane.
方法 調整 レベル?
The horizontal ruler is equipped with horizontal bubbles. Generally, the horizontal ruler has three glass tubes, each with a bubble. The horizontal glass tube is used to measure the horizontal plane, the horizontal glass tube is used to measure the vertical plane, and the other is generally used to measure a 45 degree angle. The three bubbles are used to measure whether the measurement surface is horizontal. If the bubble is centered, it is horizontal. If the bubble deviates, the plane is not horizontal; When adjusting, place the level ruler on the object being measured. If the bubble of the level ruler leans towards which side, it indicates which side is higher. That is, it is necessary to lower the height of that side or increase the height of the opposite side. Adjusting the bubble to a horizontal state indicates that the object being measured is horizontal in that direction.
