Indoor Laser Level Calibration
Calibration of Indoor Laser Level is essential to ensure that objects remain level, whether you are leveling indoors or outdoors. If a laser level fails to maintain calibration, the objects you level may be inaccurate. Even if you send your laser in for calibration every six months, it does not guarantee that it will always be accurate when you use it.
Generally speaking, laser levels will not lose calibration on their own, but a severe drop or impact may affect their accuracy. Additionally, long-term exposure to vibrations may also cause loss of calibration. Therefore, it is essential to regularly check the calibration status of your laser before any important work, especially when more than one person is using the tool.
So How Can You Check The Calibration Of Your Indoor Laser Level?
There are a number of ways to check the calibration of Indoor Laser Level, although different types of laser levels (such as rotary lasers, line lasers, and point lasers) are similar in basic principles.
A common way to check is to compare the laser level to another laser or optical level. However, this method is not ideal because it relies on the reference device you are using being in a fully calibrated state. A more effective way is to check the accuracy of the laser by self-comparison.
The specific steps are as follows: First, place the laser level on a flat surface and observe the position of the bubble. Then, rotate the level 180 degrees, place it back on the same surface, and check the position of the bubble. If the bubble remains consistent between the two positions, the level is still accurate; if the bubble position changes, it means that the level may have lost calibration. In this way, you can effectively determine the calibration status of the laser level.
There are several ways to check the accuracy of Indoor Laser Level:
When performing these tests, make sure that the environmental conditions (such as wind, vibration, etc.) are as stable as possible to obtain accurate measurement results.
Place Indoor Laser Level on a surface with a known level, start the laser, and compare it with the reference line to see if the laser line is consistent with the reference line.
90-degree cross method:
Set up two Indoor Laser Level on a flat surface and emit two laser lines to form a 90-degree cross. Measure the distance between the straight line and the two laser lines at the intersection to check whether the right angle is maintained.
Vertical test:
Place the laser level vertically, illuminate the laser to a calibrated height (such as a wall or a measured surface), and then measure the deviation of the laser position from the predetermined position at different heights.
Distance test:
Use a measuring tool (such as a tape measure) to measure the deviation of the landing point of the laser line from the target point at a fixed distance (such as 10 meters, 20 meters, etc.) to evaluate the accuracy.
Using a level:
Place a traditional level under the laser line of the laser level to check whether the laser line is at the same level as the bubble of the level.
Compare With Other Equipment
Use another calibrated Indoor Laser Level for comparison and check the difference between the two.
On-site check of laser level calibration The second method I will cover is more of an on-site check and is particularly useful for 360 line or rotary lasers. This should be done before a large job such as pouring a slab and only takes a few minutes and can make your job much more efficient and quicker. First level your site as normal and stake it, string it or whatever you would normally do. Take your laser level/tripod and move it to the other side of the site, preferably with the other side of the laser towards the center of the site. Power it on and check your levels, they should be within the laser range of the laser. It is best to move the machine to a third position and check again. This should be standard for any large scale levelling but is often overlooked because people think that the last time they used the laser level it was good so it should be good now too.
Cross-Line Indoor Laser Level Alignment Check
The third method I will describe is for cross-line lasers, for those that do not have 360-degree coverage. The purpose of this method is to see if the level is indeed level. Turn on the laser in the room and shine it at a wall, and tap a piece of paper to the wall at the height that the level is shining. Rotate the laser body so that the left edge of the line is just visible on the paper and mark the height. Carefully rotate the laser body so that the rightmost edge of the laser line is now on the paper and make another mark. After marking, straighten the tape measure and observe whether they are straight. If the height of the two marks is the same or very close, the level is good.
In most cases, if the horizontal line is good, any vertical line is likely to be good as well. If your laser has multiple vertical lines, you can check them against each other to ensure consistency. This method of detection is not demanding and can be done by yourself at home.
Checking Plumb
To check plumbness from floor to ceiling, you can use a laser with plumb function. Place the laser on the ground and mark a dot or cross on the floor. Then, mark the plumb dot or cross upwards on the ceiling. Next, rotate the laser body 90 degrees three times and observe the floor and ceiling marks to check whether the laser can provide a plumb dot or cross that is consistent with the initial mark.
The above method will cover about 90% of lasers. Give you the opportunity to quickly check the calibration of the Indoor Laser Level on site without the need for specialist equipment. If you find that the laser does need to be recalibrated, you can contact us, and we also have repair stations abroad to get you back to use the machine faster.
