How To Calibrate Bosch grl250 Laser Level

Everything You Need To Know About Calibrating Laser Level

It’s beneficial to have a laser level on hand. Particularly if you are installing flooring, mounting cabinets, hanging a lot of photographs, or framing walls, its function is to reflect a level, straight line against a wall so that you can verify that the object you are hanging is straight. Therefore, calibrating your laser level is crucial.

Even though your laser level may be advertised as “self-leveling,” you must periodically check for accuracy and adjust accordingly.

We looked for the most straightforward and effective ways to assist you in your quest to learn how to calibrate the Bosch Grl250 laser level. Discover why you can and what to do by reading on.

What Does It Mean To Calibrate A Laser Level?

A laser level must be calibrated to be accurate and produce a perfectly level line. The laser line’s source, the gadget’s internal pendulum, may be adjusted to do this by opening the device and doing so. With self-calibration buttons, you can alter the laser line on some laser levels by pressing up and down buttons. For most models, like the Bosch Grl250 laser level, the accuracy is about 1/16th of an inch.

Why You Need To Calibrate Laser Level

It would help if you calibrated your laser periodically to ensure that it consistently produces a flawlessly level line. Every laser level has a locking mechanism for storage when not in use. This maintains the internal pendulum’s position. The pendulum will bounce around within the gadget and become thrown off if you don’t lock it up and are careless with the laser level (for instance, if you drive around with it bouncing around in the back of your truck). Therefore, before altering your laser level, make sure to lock it.

Remember that a less costly laser level will likely require more frequent calibration than a more expensive one. Therefore, if you decide to get a cheaper one, you might have to calibrate the level more frequently.

Can You Calibrate A Laser Level By Yourself?

Yes, you can calibrate the laser level independently, even if it is a little complicated. If your level is self-calibrating, all you’ll need is a tape, perhaps some paper, and a pen (depending on your preference). If it is not self-calibrating, you will require a small screwdriver to loosen tiny screws within the laser level.

How To Calibrate A Laser Level

1. Verify the accuracy 

Check to determine whether your laser is incorrect first. There are three methods you may use to do this. Select the one that best meets your criteria for accuracy and is most convenient.

  • First Approach: The laser level should first be set up on a tripod. If you believe the tile has been set evenly in the first place, the first technique involves shining the laser lines onto some wall tile. As you can check the Y and X axes simultaneously, this method is certainly the quickest, but it also introduces more variables that might lead to erroneous results.
  • Second Approach: Another approach is to use the laser line to mark two distinct areas on a wall. Make sure the laser line touches the tape line and that the tape is placed precisely beneath the line. Place the laser level on the tripod, move it to a different room area, and then line the laser line up as precisely as you can on the second piece of tape. Check the first marking to determine whether the line is off.
  • Third Approach: If you are working in a small area and do not have room to adjust the laser level, this can be an excellent technique to check for accuracy. As previously, begin by pointing the laser level toward a wall at least 20 feet away. Mark the line’s location on a piece of paper by taping it to the wall. You might want to use a straightedge or ruler to get it perfectly straight. The light should then be shone on the same area after 180 degrees of rotation of the laser level. You may mark a second line at 90 degrees rotation if your laser has a Y axis. Take note of the variations between the lines. It’s time to calibrate the level of the deviation from the mark exceeding the accuracy range specified in the handbook. If your laser level, for instance, claims to be 1/16th inch precise, that means that the lines must be wider than 1/16th of an inch to make adjusting the laser level necessary. Press the up and down buttons as directed in your laser level’s handbook to calibrate self-calibrating models.

2. If manually calibrating, open the level and check the wires

Remove all the level screws to reveal the device’s body and remove the batteries. To ensure the wires are not obstructing the pendulum, gently tug on them with your screwdriver. Otherwise, this will undoubtedly skew your level line.

  • Adjust Screws Inside The Body For Calibration

A very little screwdriver is required for this procedure. There will be two screws holding the pendulum in place if your laser level has an X and Y axis.

Reinstall the batteries at the laser level and place it back on the tripod; you want the laser to turn on at this point. Check that the pendulum is locked before removing one of the screws holding it in place. Lock it, swing it a couple of times back and forth, and then leave it alone. Using your level measurements on the wall, ensure the line is perfectly straight. Put the screw back in, lock it back up, and then unlock it to test whether it’s level again.

Follow the steps below for the other axis as well:

Step 1: Check And Recheck

While the level’s body is open, you should check for levelness multiple times after you’ve put everything back together. While checking for correctness, use the lines you have already drawn. Restart this procedure from step 1 and draw new lines to indicate your laser level line locations for additional accuracy tests.

Step 2; Consult Professionals

At this point, hopefully, you have calibrated your level correctly, and it is back to its best. But if not, hold onto hope. Some qualified experts can calibrate your level with more exact measurements. These experts may be located online.

How Often Should I Calibrate My Laser Level?

How gently you use your laser level will determine the outcome. You should verify the level of accuracy at least every six months if you are not securing the pendulum, keeping it in a rough environment, or dropping it frequently.

However, if you handle it carefully, you may maintain its accuracy for up to a year. Never forget to lock the pendulum, gently rotating it.

Final Thoughts

Do not allow a misaligned laser level to impede your progress. You can now restart your operation at a super-accurate level that you calibrated yourself. If not, you gave it your best effort and had it polished for you by an expert. In either case, congrats on learning more about keeping your laser level accurate for many future tasks.
