HOW TO CALIBRATE A LASER LEVEL
Set up the laser on a tripod at about 100 feet from a wall, and rotate it with the front pointing to a wall. Turn on the detector and the laser level. When the detector indicates level, mark the wall accordingly. Rotate the laser 180 degrees, and make a mark by using the detector again. Calculate the difference between these two marks to make sure it’s within the device’s specified accuracy. Rotate the laser 90 degrees, and make another mark by using the detector. Calculate the difference between this mark and the previous one. If it’s within the device’s specified accuracy, it’s ready to be used. Otherwise, it will have to be professionally calibrated.
HOW TO USE A LASER LEVEL
Set up the laser level on a tripod or flat surface. If it’s a manual level, you will have to make sure the bubble vials show level. Turn on the laser level. If it’s a self-leveling model, give it a moment to level itself. Once the device has been set up, it will emit a laser that shows level either on a wall or across an outdoor workspace. And depending on the type of laser, it could be dot, multiple line, or rotary (which shows 360 degrees of level either horizontally or vertically). You can use a detector to intercept the laser if there’s no wall to “catch” it, which is typically needed outdoors. Attach the detector to a measuring rod and move it up or down until you hear beeping. This indicates that the detector has found the laser. Secure the detector to the rod and make your measurements as necessary.
