How do i calibrate my pls5 - Pacific Laser Systems PLS5 Automatic Laser Plumb Level And Square

The handhelds are not meant to be calibrated, recycle properly and invest in a PLS3 or PLS5, they have a 3 year exchange warranty: https://www.plslaser.com/pls-best-class-warranty/

CALIBRATION COMPLETE
Refer to Electronic Compass Calibration do you have an owners manual ?
Compass Calibration
The compass direction will show CAL if it needs to be calibrated. Before calibrating the compass, drive the vehicle to an area that is magnetically clean (free of large metallic objects).

1. Turn ON the ignition.
2. Before calibrating the compass, make sure the compass is set to the variance zone in which the vehicle is travelling. See Compass Magnetic Variation Adjustment below.
3. Press the vehicle information button until the PRESS TO CALIBRATE COMPASS screen is displayed.
4. Press the set/reset button to start the compass calibration.
5. The DIC will display CALIBRATING: DRIVE IN CIRCLES. Drive the vehicle in circles at less than 8 km/h (5 mph) to complete the calibration. The DIC will display CALIBRATION COMPLETE when the calibration is complete.

Simple answer, you cant. The PLS hand held lasers are not designed to be opened, or repaired. You will have to remove a decal to get the screws to open it, and doing so will mean the laser wont be sealed anymore. They are very susceptible to dust and debris. You can get it replaced with a PLS etn, from a PLS retailer. For free if you're under warranty, and for a reduced cost, if your not.

In my experience, on PLS found several times the power button defective after few weeks/months (especially if You work in construction sites ).
The ultimate fix is new power button (not replace the old one!) in a convenient position. I have fix several PLS3:


Notice: if You open your PLS5, You have to break the lateral sticker and the warranty will be void!! Keep this in mind!!

Bye!

It could be a broken wire. If it's a new PLS model, then you can remove the back cover and genitally remove the core, and look to see if any of the thin wires are broken. if not the laser diode is burnt out. If you have an old model with the power button on the top of the unit, then don't open it, it wont close again.

PLS tools are not designed to be repaired. There was a time when PLS made replacement parts, however they changed from that business model and now when things break or go out of spec. they are replaced with an ETN (Equivalent to New) units. Either for free, if they are under warranty, or at a lower cost, if not. Bring your laser to a PLS retailer, and they should be able to take care of you.

Calibrating a digital pocket scale like the Mega Weigh MGP-1014 ensures that it provides accurate measurements. Here are the general steps for calibrating such a scale:
Note: It's important to refer to your scale's user manual for specific instructions, as calibration methods can vary between different models.
What You'll Need:

• Calibration weights (these are weights with known, precise values)
• The Mega Weigh MGP-1014 scale
• A clean, stable surface for calibration

Steps:

1. Read the Manual: Familiarize yourself with the user manual that came with the scale. It should provide specific instructions on how to calibrate the scale.
2. Clean the Scale: Ensure that the scale's weighing platform is clean and free from any debris. This helps to prevent interference with the calibration process.
3. Power On: Turn on the scale and wait for it to stabilize, displaying "0.0" or the default reading.
4. Tare (Optional): If your scale has a tare function, you can use it to zero out the weight of any container you plan to use to hold the calibration weights. Place the empty container on the scale and press the tare button.
5. Select Calibration Mode: Many scales have a calibration mode that you need to access. Refer to your user manual to determine how to enter the calibration mode on the Mega Weigh MGP-1014.
6. Add Calibration Weight: Place a calibration weight of a known value onto the scale's platform. The weight should match the unit of measurement you plan to use (grams, ounces, etc.).
7. Calibration Procedure: Follow the specific instructions provided in the user manual to initiate the calibration procedure. This usually involves pressing buttons or following on-screen prompts. The scale will often ask you to confirm the weight value of the calibration weight you added.
8. Confirm or Adjust: The scale should display the weight you added as the calibration weight. Confirm that the displayed weight matches the known value of the calibration weight. If there's a discrepancy, follow the manual's instructions to adjust the calibration setting accordingly.
9. Repeat if Necessary: Some scales require calibration with multiple weights to ensure accuracy across the scale's entire range. If this is the case, follow the manual's instructions for using additional calibration weights.
10. Exit Calibration Mode: Once you've completed the calibration procedure, exit the calibration mode according to the instructions provided in the user manual.
11. Test with Known Items: After calibration, test the scale's accuracy by weighing objects of known weight to ensure that it's providing accurate readings.

Remember that the exact calibration process can vary depending on the scale model, so always refer to the user manual for the most accurate instructions. If you're unsure about any step, it's recommended to contact the manufacturer's customer support for assistance.

one of the problems with this type of equipment is the fact that the down beam has to be set to a true plumb position. If it is possible to swing the head without disturbing the mounting you can check for circling - motion of the down beam in a circular pattern - which indicates off plumb placement.

The green LED on top is the power indicator. The PLS5 has 5 optic windows that should produce beams. Do Not look into the windows to see if there is a beam. Place your hand in front of each window. If there is no beam from any of the windows the unit is malfunctioning and requires service by an authorized service center. PLS states that there is NO service or repair that can be performed by the consumer beyond replacing the batteries and cleaning the optic windows This unit has a 1 year warranty from PLS.

They did a perfect job on my laser transit

I will double check but pretty certain it was just out of adjustment in some way.
