When purchasing a new level, you might want to know if it is accurate because sometimes, by mistake, a faulty level might find its way on the market from the manufacturer. Accidents do happen and you might drop your level when working. In these two situations, you might need to confirm if the level is providing the correct readings. This article is going to take you on the steps on how to check your level for accuracy.
Things You’ll Need for The Test
● A surface that is flat and longer than your beam level.
● You’ll require to mark the position of your level on the surface so that you can place it on the same spot when you rotate the level and that means you need a pencil or chalk.
Checking Level Accuracy on a Horizontal Surface
The first step requires you to check the readings and how the bubble vial is positioned. To do this, place your level on the flat surface you chose earlier and record the reading and note the position of the bubble vial.
There are different types of levels and depending on which level you are using you can tell the difference from one side to the other. An example is some levels have a single mill on one side and doesn’t on the other side. It becomes easier to identify which side you had placed first to avoid confusion.
Since your focus is how to check your level for accuracy, it isn’t important to have a leveled surface because that will not alter the accuracy of your level. What matters is the reading or the position of the bubble vial
When you place the level on the surface mark the position of the level and note the position of the bubble vial. Rotate the level 180° horizontally and place it on the same position you had marked earlier and note the position of the vial again.
After going through all the above steps, this now is how to check your level for accuracy. If the vial position in the first step was the same when you rotated the level, then your scale is accurate, but if the position changed when you rotated the level, your level is faulty.
Plumb Accuracy on a Level
When testing for the vertical accuracy, you need a vertical surface such as a door. Place your level vertically against the door and mark the position of your level at the very end and note the bubble vial position. Flip your level 180° and place it again on the same position as before and note the vial position.
To check your level for plumb accuracy, you need to compare the first and the second bubble position, and if they are the same, your level is accurate. In case your level doesn’t present with the same vial position you need to repeat the process and if it gives the same result your level is faulty, and you need to replace it with a new one.
