iHandy Level Free User Manual
Model: Free
1. Introduction
The iHandy Level Free application transforms your mobile device into a precise digital spirit level. Utilizing your device's built-in sensors, it provides accurate measurements for horizontal and vertical surfaces, making it a convenient tool for various tasks such as hanging pictures, leveling furniture, or checking surface inclinations.
2. Setup and Installation
- Download: Locate "iHandy Level Free" in your device's app store (e.g., Amazon Appstore, Google Play Store).
- Install: Tap the 'Install' or 'Get' button. The app will download and install automatically.
- Launch: Once installed, tap the app icon on your device's home screen or app drawer to open it.
3. Operating Instructions
The iHandy Level Free app typically displays a virtual bubble level on your screen. The operation is intuitive:
- Horizontal Leveling: Place your device flat on the surface you wish to level. The bubble will move horizontally. Adjust the surface until the bubble is centered between the two vertical lines, indicating a level horizontal plane.
- Vertical Leveling: Place the edge of your device against the vertical surface you wish to check. The bubble will move vertically. Adjust the surface until the bubble is centered between the two horizontal lines, indicating a plumb vertical plane.
- Angle Measurement: Some versions of the app may display a digital angle readout. This number indicates the tilt in degrees relative to a perfectly level surface.
4. Calibration
For optimal accuracy, it is recommended to calibrate the iHandy Level Free app. While the app's interface may vary, a common calibration method involves:
- Find a Known Level Surface: Place your device on a surface that is known to be perfectly level (e.g., using a traditional spirit level as a reference).
- Initiate Calibration: Look for a 'Calibrate' or 'Zero' button within the app's settings or on the main screen. Tap this button.
- Confirm Calibration: The app will adjust its internal reference based on the current position. Ensure your device remains still during this process.
Note: The accuracy of the app is dependent on the quality of your device's internal sensors. Regular calibration on a known level surface is advised.
5. Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Bubble is not centered when device is level. | The app may require calibration. Refer to Section 4: Calibration. Ensure your device is on a truly level surface during calibration. |
| App crashes or freezes. | Close and restart the app. Ensure your device's operating system is up to date. Clear the app's cache (via device settings). If issues persist, reinstall the app. |
| Inaccurate readings on different sides of the device. | This can be due to inconsistencies in the device's internal sensors or unevenness of the device's casing. Calibrate the app carefully. For critical tasks, consider using a physical level. |
| App requires permissions (e.g., contacts). | Some apps may request broad permissions. Review the requested permissions before granting them. If you are uncomfortable, you may choose not to use the app. |
