5.2 Power On/Off
- To Power On: Press the ON/OFF button. The display will light up.
- To Power Off: Press and hold the ON/OFF button for a few seconds. The device will also automatically power off after 3 minutes of inactivity to conserve battery.
6. Operating Instructions
6.1 Absolute Measurement Mode
By default, the device powers on in absolute measurement mode. In this mode, it measures the angle relative to a true horizontal surface (0°). Place the device on the surface you wish to measure, and the angle will be displayed.
6.2 Relative Measurement Mode (ZERO Function)
To measure the angle relative to a specific surface (e.g., setting a saw blade angle relative to the saw table):
- Place the angle finder on your reference surface (e.g., saw table).
- Press the ZERO button. The display will show 0.00°, indicating this is now your reference point.
- Move the angle finder to the object you want to measure (e.g., saw blade). The display will show the angle relative to your set zero point.
6.3 Data Hold Function
To freeze the current measurement on the display:
- Press the HOLD button once. The displayed value will be locked, and a "HOLD" icon may appear.
- Press the HOLD button again to release the measurement and return to live readings.
6.4 Unit Conversion
The device supports two units of measurement: degrees (°) and percentage (%). To switch between these units, press the U button (Unit button, typically located near the ZERO button).
6.5 Automatic Display Inversion
The display automatically rotates 180° when the device is inverted, ensuring that the readings are always upright and easy to read, regardless of the device's orientation.

7. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the angle finder in its carrying bag in a dry, cool place when not in use.
- Battery Care: Recharge the battery regularly, even if the device is not used frequently, to maintain battery health.
- Protection: Ensure the Type-C charging port is covered by its rubber seal to maintain IP54 rating.
8. Troubleshooting
8.1 "Err" Displayed
If the display shows "Err", it indicates that the tilt angle exceeds 30° (either forward or backward). The device is designed to provide accurate readings within a certain range. For angles beyond this, the "Err" message is displayed to prevent inaccurate measurements.
