Setup
Charging the Device
Before initial use, fully charge the device. The BANRIA Digital Angle Finder Gauge features a built-in 400mAh rechargeable battery. A full charge typically takes 1.5 to 2 hours and provides approximately one week of daily usage.
- Locate the USB Type-C charging port on the side of the device.
- Connect the provided USB Type-C charging cable to the device.
- Plug the other end of the USB cable into a compatible power source (e.g., USB wall adapter, portable power bank, car charger, or computer USB port).
- The battery indicator on the LCD screen will show charging status. Once fully charged, disconnect the cable.

Operating Instructions
Basic Operation
- Power On/Off: Press the ON/OFF button to turn the device on or off.
- Display Reading: The high-visibility LCD screen will display the angle data. The data will automatically invert when the tool is inverted, ensuring easy readability from any orientation.

Measurement Modes: Absolute and Relative
The device supports two measurement modes:
- Absolute Angle Measurement (ABS): Measures the angle relative to a true horizontal surface. This is the default mode when the device is powered on.
- Relative Angle Measurement (REL): Allows you to set any surface as a 'zero' reference point and measure subsequent angles relative to that point.
To switch between modes:
- Place the device on the desired reference surface.
- Short press the ZERO button. The display will show "0.00°" and indicate the relative mode.
- Move the device to measure the new angle relative to your set zero.
- Short press the ZERO button again to return to Absolute Angle Measurement.

Hold and Slope Function
The HOLD/Tilt% button has two functions:
- Hold Angle Data: A short press of the HOLD/Tilt% button will freeze the current angle reading on the display. Press again to release.
- Switch Angle/Slope: A long press (2-3 seconds) of the HOLD/Tilt% button will switch the display between angle (resolution: 0.05°) and slope (resolution: 0.01).

Magnetic Base Usage
The BANRIA Digital Angle Finder Gauge is equipped with four strong magnets on its sides, allowing it to securely attach to various metal surfaces. This feature is particularly useful for hands-free operation on tools like miter saws, band saws, and table saw blades, ensuring stable and accurate measurements.

Laser Function
The device includes a line laser feature to assist with alignment. The laser can be activated or deactivated by pressing the ON/OFF button, which also functions as the laser switch. This laser helps in visually extending the measurement line for improved accuracy in certain applications.

Maintenance
To ensure the longevity and accuracy of your BANRIA Digital Angle Finder Gauge, follow these maintenance guidelines:
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in its portable pouch when not in use to protect it from scratches and impacts. Keep it in a dry environment.
- Water and Dust Resistance: The device is IP54 rated, meaning it is protected against dust ingress and splashing water from any direction. While it offers protection, avoid submerging the device in water or exposing it to heavy rain.
Troubleshooting
Here are solutions to common issues you might encounter:
- Device does not turn on: Ensure the battery is charged. Connect the device to a power source using the USB Type-C cable and allow it to charge for at least 15 minutes before attempting to power it on again.
- Device turns off automatically: This is a normal feature designed to conserve battery. The angle finder will automatically turn off after 3 minutes of no operation. Press the ON/OFF button to reactivate it.
- Inaccurate readings or 'Zero' button not working as expected: Ensure you are following the correct procedure for switching between Absolute and Relative Angle Measurement. A short press of the ZERO button toggles between these modes. If the issue persists, try recalibrating the device by placing it on a known level surface and pressing the ZERO button to set a new reference.
- Display is difficult to read: The LCD screen automatically inverts. Ensure the device is positioned so the display is facing you directly.
