2. Setup
2.1 Unpacking and Initial Inspection
Carefully remove the digital angle finder from its packaging. Inspect the device for any signs of damage. Ensure all components, including the USB-C charging cable and belt bag, are present.
2.2 Charging the Battery
The device is powered by an internal 400mAh Li-Polymer rechargeable battery. Before first use, it is recommended to fully charge the device.
- Connect the provided USB-C charging cable to the charging port on the device.
- Connect the other end of the USB-C cable to a standard USB power adapter (not included) or a computer USB port.
- The battery indicator on the display will show charging status. A full charge typically takes approximately 2-3 hours.
- Once fully charged, disconnect the charging cable.

3. Operating Instructions
3.1 Power On/Off
- Press the ON/OFF button to turn the device on. The display will light up.
- Press and hold the ON/OFF button for a few seconds to turn the device off.
3.2 Measurement Modes
The device supports two primary measurement modes:
- Absolute Angle Measurement (ABS): Measures the angle relative to a true horizontal plane (0°).
- Relative Angle Measurement (REL): Allows you to set any surface as a temporary 0° reference point to measure subsequent angles relative to that reference.

3.3 Zeroing Function
To set a relative zero point:
- Place the angle finder on the desired reference surface.
- Press the ZERO button. The display will show 0.00°.
- All subsequent measurements will be relative to this new zero point.
3.4 Hold Function
To hold the current reading on the display:
- Press the HOLD button. The current angle will be frozen on the screen.
- Press the HOLD button again to release and resume live measurement.
3.5 Unit Conversion (Degrees / Slope Percentage)
To switch between degrees (°) and slope percentage (%):
- Press the TILT% button to toggle between the two units.
3.6 Laser Operation
The dual lasers assist in precise alignment and marking.
- Press the laser button (often integrated with ON/OFF or a dedicated button, refer to device markings) to activate the lasers.
- The lasers project lines to indicate the measured angle, useful for tasks like hanging decorations or aligning cuts.
- Caution: Do not stare directly into the laser beam. Avoid pointing the laser at people or animals.
3.7 Magnetic Base Usage
The strong magnets on all four sides allow the device to securely attach to metal surfaces, providing hands-free operation.

4. Maintenance
4.1 Cleaning
The device has an IP67 dust-proof and waterproof rating, allowing for use in various environments. To clean:
- Wipe the device with a soft, damp cloth.
- Do not use abrasive cleaners or solvents, as these may damage the display or casing.
- Ensure the charging port cover is securely closed to maintain water resistance.
4.2 Battery Care and Storage
- To prolong battery life, avoid fully discharging the battery frequently. Recharge when the battery indicator is low.
- Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
- If storing for an extended period, charge the battery to approximately 50% every few months.
- Use the provided belt bag for protection during storage and transport.
5. Troubleshooting
If you encounter issues with your COROLLATA Digital Angle Finder, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low or depleted battery | Charge the device using the USB-C cable. |
| Inaccurate readings | Device not zeroed correctly; external interference | Ensure the device is placed on a stable, level surface before zeroing. Re-zero the device. Avoid strong magnetic fields during use. |
| Display is dim or unreadable | Low battery; extreme lighting conditions | Charge the battery. The bright backlight should assist in most conditions, but direct harsh sunlight can still affect visibility. |
| Lasers not visible | Lasers not activated; low battery; bright ambient light | Press the laser activation button. Charge the device. Use in conditions where the laser line is more visible. |
If the problem persists after attempting these solutions, please contact COROLLATA customer support for further assistance.
