- Place the battery into the compartment and close the cover securely.
5. Operating Instructions
5.1. Power On/Off
- Press the ON/OFF button to turn the device on or off.
- The device will automatically power off after 5-6 minutes of inactivity. To reactivate, simply move the scale.
5.2. Zeroing the Display
- To set the current position as zero, press the ZERO button. This is useful for relative measurements.
5.3. Angle Measurement
To measure an angle:
- Ensure the device is powered on.
- Place the base of the protractor firmly against one surface of the angle you wish to measure.
- Adjust the movable ruler until it aligns with the second surface of the angle.
- Read the angle displayed on the LCD screen.
- Use the center knob to lock the ruler in place for transferring angles.

5.4. Hold and Reverse Function (H/R Button)
- Short Press: Press the H/R button briefly to lock the current reading on the display. This is useful for retaining a measurement.
- Long Press: Press and hold the H/R button to reverse the display reading by 180°. This allows for easier reading when the device is inverted.
Figure 5: Illustration detailing the functionality of the H/R button: a short press locks the reading, and a long press flips the reading 180 degrees for convenience.
5.5. Using the Bubble Levels
The integrated horizontal and vertical bubble levels assist in ensuring the device is perfectly level or plumb before taking measurements or marking lines. Observe the bubble within the vial; when it is centered between the two lines, the surface is level or plumb.
6. Care and Maintenance
- Keep the device clean and dry. Wipe with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Avoid exposing the device to extreme temperatures or high humidity.
- Store the device in a protective case when not in use to prevent damage to the display or ruler.
- Remove the battery if the device will not be used for an extended period to prevent leakage.
7. Troubleshooting
- Display Not Working: Check if the battery is correctly installed and has sufficient charge. Replace the battery if necessary.
- Inaccurate Readings: Ensure the surfaces being measured are clean and free of debris. Recalibrate by pressing the ZERO button on a known flat surface.
- Buttons Unresponsive: Ensure the device is not in a locked state (e.g., if the H/R button was pressed to hold a reading). If issues persist, try removing and reinserting the battery.
