4. Setup
4.1 Battery Installation
- Locate the battery compartment cover on the back of the device.
- Open the cover.
- Insert 2 AA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
4.2 Initial Power On
Press the ON/OFF button to power on the device. The backlit LCD display will illuminate, showing the current angle reading.
5. Operating Instructions
5.1 Power On/Off
- To Power On: Short press the ON/OFF button.
- To Power Off: Press and hold the ON/OFF button for approximately 3 seconds.
5.2 Measurement Modes (Absolute vs. Relative)
The inclinometer supports both absolute and relative measurement modes.
- Absolute Measurement Mode: Measures the angle relative to a true horizontal surface.
- Relative Measurement Mode: Allows you to set any surface as a temporary zero reference point for measuring subsequent angles.
To switch between modes, press the ZERO button. In relative mode, the display will show '0.00°' after pressing ZERO, indicating the new reference point.

Figure 2: Illustration of Absolute and Relative Measurement Modes.
5.3 Unit Switching
The device can display measurements in four different units: Degrees (°), Percentage (%), mm/m, and in/ft.
- To cycle through the measurement units, short press the MODE button.

5.4 Hold Function
The HOLD function allows you to freeze the current reading on the display for easier viewing, especially in hard-to-reach areas.
- To activate the HOLD function, short press the HOLD button. The reading will freeze, and a 'HOLD' indicator may appear on the screen.
- To release the HOLD function and resume live readings, short press the HOLD button again.
5.5 Automatic Screen Flip
The display automatically rotates 180° when the device is inverted, ensuring the numbers are always upright and easy to read from any orientation.
