2. Setup
2.1 Unpacking the Device
Carefully remove all components from the packaging. Ensure all items listed below are present:
- 1 x Digital Inclinometer
- 1 x USB Type-C Cable
- 4 x Double-sided Tape
- 1 x Storage Bag
- 1 x User Manual (this document)

2.3 Initial Power On
Press and hold the power button (usually the central button) for a few seconds until the LCD screens illuminate. The device will perform a brief self-check before displaying the current angle readings.
3. Operation
3.1 Power On/Off
- Power On: Long press the power button.
- Power Off: Long press the power button again. The device may also have an auto-off feature after a period of inactivity to conserve battery.
3.2 Display Overview
The device features dual LCD screens providing comprehensive information. Refer to the diagram below for an explanation of the display elements.

3.3 Single Axis Measurement
For single-axis measurements, place the device on the surface you wish to measure. The display will show the angle relative to the horizontal plane. The measuring range for single axis is 4*90°.
3.4 Dual Axis Measurement
The inclinometer can simultaneously display angles for both the X-axis and Y-axis. This is useful for checking the levelness and plumb of surfaces in two dimensions. The dual-axis measuring range is ±40°.

3.5 Laser Level Function
The device includes a dual laser level feature. Short press the laser control button (indicated on the display diagram) to activate the horizontal and vertical laser lines. These lasers provide clear, sharp lines for alignment tasks.
3.6 Unit Conversion
The inclinometer supports multiple measurement units. Use the unit switch button (indicated on the display diagram) to cycle through degrees (°), percentage (%), mm/m, and in/ft as needed for your application.
3.7 Calibration
The device supports auto-calibration. For optimal accuracy, it is recommended to perform calibration periodically or if you suspect inaccurate readings. Refer to the on-screen prompts or a dedicated calibration section in the full manual for detailed steps.
3.8 Magnetic Base Usage
The strong magnetic base allows the inclinometer to be securely attached to metal surfaces, freeing your hands for other tasks during measurement. This is particularly useful for working with metal frames, pipes, or machinery.

4. Maintenance
4.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the laser apertures and display screens are kept clean for optimal performance.
4.2 Storage
When not in use, store the inclinometer in its provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid storing it in environments with high humidity or dust.
4.3 Battery Care
To prolong battery life, avoid fully discharging the device frequently. If storing for an extended period, charge the battery to approximately 50% and recharge every few months.
5. Troubleshooting
5.1 Common Issues
- Device does not power on: Ensure the battery is charged. Connect to a Type-C charger and try again.
- Inaccurate readings: Perform a calibration as described in the full user manual. Ensure the measurement surface is stable and free from vibrations.
- Laser not visible: Check if the laser function is activated. Ensure the environment is not too bright, which can diminish laser visibility.
- Display is blank or frozen: Try resetting the device by holding the power button for an extended period (e.g., 10-15 seconds) or allowing the battery to fully discharge and then recharging.
