To use the Unit LM320D, power on the device and place the magnetic base firmly against the surface you wish to measure. The display will immediately show the current angle. You can toggle between absolute and relative measurement modes to set a reference point as needed. The Data Hold function allows you to freeze the reading on the screen for easier recording in tight spaces, while the automatic screen rotation ensures the numbers remain upright for the user.

What to consider before purchase

• Verify that the measurement range meets your specific project requirements.
• Ensure the magnetic base is compatible with the materials you typically work with.
• Consider the need for periodic calibration if used in professional settings.
• Check the dimensions to ensure the device fits into your intended workspace.

For optimal performance, keep the sensor surface clean and free of debris. Charge the device fully before extended use to ensure the 14-hour battery life is maintained. Store the inclinometer in a dry, protective case when not in use to prevent damage to the display or internal components.
