How to use

To begin using the Uni-T LM320E, ensure the device is fully charged via the provided USB-C cable. Power on the unit and place it on the surface you wish to measure. The magnetic base will hold the device firmly against ferrous materials. Use the mode button to toggle between absolute and relative measurement settings as required for your specific task. The dual lasers can be activated to project reference lines for alignment. The screen will automatically rotate based on the device's orientation, and you can use the data hold function to freeze the measurement on the display for easier recording.

What to consider before purchase

• Check if the magnetic base is compatible with the materials you typically work with.
• Verify that the measurement units provided meet your specific project requirements.
• Consider the operating time if you plan to use the device for extended periods without access to a charger.

Usage recommendations

For the most accurate results, calibrate the device on a flat, level surface before starting your project. Always ensure the magnetic base is clean and free of debris to maintain a secure grip on metal surfaces. Store the device in a dry place when not in use to protect the laser optics and internal electronics.
