3. Product Overview
Familiarize yourself with the components and controls of your PREXISO Laser Measure.
This diagram details how to switch between measurement units (M/In/Ft) and select different measurement reference points (front, back, or extension) on the PREXISO Laser Measure's display.
The image shows the PREXISO Laser Measure's screen displaying multiple stored measurements, along with instructions on how to navigate, read, and delete data from its 100-group memory.
This image highlights the compact size of the PREXISO Laser Measure (4.5 x 1.9 x 1.0 inches) and points out features such as the built-in bubble level, high accuracy, sound mode, 180s auto power-off, and 215 ft measuring distance.
The device features a large LCD screen for clear readings, an intuitive button layout for easy operation, a laser aperture for emitting the measurement beam, and a built-in bubble level for horizontal alignment. It also includes an extension piece for precise diagonal measurements.
4. Setup
4.1 Battery Installation
- Locate the battery compartment on the back of the device.
- Open the battery cover.
- Insert the two AAA alkaline batteries, ensuring correct polarity (+/-).
- Close the battery cover securely.
4.2 Powering On/Off
- To power on: Press the ON button.
- To power off: Press and hold the OFF/CLEAR button (red 'C' button) for a few seconds, or the device will automatically shut down after 180 seconds of inactivity to conserve battery life.
4.3 Initial Settings (Units)
After powering on, you can change the measurement units:
- Press the UNITS button repeatedly to cycle through the available units: Meters (M), Inches (In), Feet (Ft), and Feet+Inches (Ft+In).
5. Operating Instructions
5.1 Changing Measurement Reference Point
The device can measure from the front, back, or extension piece. This is crucial for accurate measurements.
- Short press the reference point button (icon with a ruler and arrows) to switch between the different reference points. The active reference point will be indicated on the display.

5.2 Measurement Modes
The PREXISO Laser Measure offers six distinct measurement modes:
This graphic visually explains the six versatile measurement modes available on the PREXISO Laser Measure, including basic distance, continuous tracking, area, volume, and two types of Pythagorean calculations.
To select a mode, press the MODE button (icon with multiple squares) repeatedly until the desired mode icon appears on the display.
5.2.1 Single Distance Measurement
- Ensure the device is in single measurement mode.
- Aim the laser at the target point.
- Press the ON button once. The measurement will be displayed instantly.
5.2.2 Continuous Measurement (Min/Max)
- Select continuous measurement mode.
- Press the ON button. The device will continuously measure as you move it.
- The display will show the current measurement, along with the minimum and maximum distances recorded during the continuous measurement.
- Press the ON button again to stop continuous measurement.
5.2.3 Area Measurement
- Select area measurement mode.
- Measure the first side (e.g., length) by pressing ON.
- Measure the second side (e.g., width) by pressing ON again.
- The device will automatically calculate and display the area.
5.2.4 Volume Measurement
- Select volume measurement mode.
- Measure the length, then the width, then the height, pressing ON after each measurement.
- The device will automatically calculate and display the volume.
5.2.5 Pythagorean Measurement (2-point & 3-point)
These modes allow indirect measurement of heights or distances using the Pythagorean theorem.
- 2-Point Pythagoras: Used to measure height when you can measure the hypotenuse and one leg of a right triangle. Follow the on-screen prompts to take the two required measurements.
- 3-Point Pythagoras: Used for more complex indirect height measurements, often when the base cannot be directly measured. Follow the on-screen prompts to take the three required measurements.
5.3 Mute Function
To turn the beep sound on or off, press the MUTE button (speaker icon) once. This is useful for quiet environments.
5.4 Data Storage and Retrieval
The device can store up to 100 groups of measurements.
- Saving Data: Measurements are automatically saved after each completed measurement.
- Retrieving Data: Press the RECORD button (book icon) to view stored data. Use the ADD/SUBTRACT buttons (+/-) to navigate through records. Long press to skip ten storage data entries.
- Deleting Data: To delete the currently displayed record, short press the OFF/CLEAR button (red 'C' button). To delete all stored data, long press the OFF/CLEAR button.
6. Maintenance and Care
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Clean the laser lens gently with a soft cloth, similar to cleaning camera lenses.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. Always use new AAA alkaline batteries.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Durability: The device has an IP54 rating, meaning it is protected against dust ingress and splashing water from any direction. However, it is not fully waterproof and should not be submerged.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Dead or incorrectly installed batteries. | Check battery polarity. Replace with new AAA batteries. |
| Inaccurate measurements | Incorrect reference point selected; Obstruction in laser path; Target surface too reflective or absorbent. | Verify the correct measurement reference point. Ensure a clear line of sight. Use a target plate for difficult surfaces. |
| Laser beam not visible outdoors or in bright light | High ambient light conditions. | This is normal for laser measures. The device is not recommended for outdoor use in bright sunlight. Use a target plate or measure in shaded areas. |
| Display shows 'Error' | Measurement out of range; Internal error. | Ensure target is within 215ft range. Turn off and restart the device. If error persists, contact support. |
| No sound/Beep not working | Mute function is active. | Press the MUTE button to toggle the sound on. |
