5. Setup

5.1 Initial Charging

Before first use, fully charge the inclinometer using the provided Type-C USB cable.

1. Locate the Type-C charging port on the side of the device.
2. Connect the Type-C cable to the device and the other end to a USB power source (e.g., computer, wall adapter).
3. The battery indicator on the LCD will show charging status. A red light indicates charging, and the light turns off when fully charged.

6. Operating Instructions

6.1 Power On/Off

• To Power On: Long press the red Power button.
• To Power Off: Long press the red Power button again. The device also features an automatic shutdown after 12 minutes of inactivity.

6.2 Switching Display Units (Angle/Slope)

• Short press the H/% button to toggle between angle (°) and slope ratio (%).

6.3 Data Hold

• To hold the current measurement on the screen, long press the H/% button.
• Long press the H/% button again to release the hold and resume live measurement.

6.4 Absolute and Relative Measurement

• Absolute Measurement: The device defaults to absolute measurement mode, displaying the angle relative to the true horizontal plane.
• Relative Measurement: To set a custom zero point for relative measurement, place the device on your desired reference surface and short press the ZERO button. The display will show '0.00°' and 'REL' (Relative) indicator. Subsequent measurements will be relative to this new zero point.
• To return to absolute measurement, short press the ZERO button again.

6.5 Auto-Rotate Screen

The display automatically rotates 180° when the device is inverted, ensuring readability from any orientation.

6.6 Laser Function (Optional)

For models equipped with a laser:

• Short press the Power button to turn the laser on or off.
• Always aim the laser away from your eyes and other people.

7. Calibration Procedure

Recalibrate the device after impact or significant temperature changes to maintain accuracy. The calibration process involves several steps:

1. Step 1: Place the inclinometer on a flat, horizontal surface. Long press both the Power button and the H/% key simultaneously until the screen displays "CR.d1" and you hear a beep. This indicates entry into calibration mode.
2. Step 2: With "CR.d1" displayed, rotate the instrument 180° (keeping it on the same flat surface). Press the H/% key to confirm. The screen will display "CR.d2" and you will hear a beep.
3. Step 3: With "CR.d2" displayed, rotate the instrument 90° to a vertical position (e.g., against a wall). Press the H/% key to confirm. The screen will display "CR.d3" and you will hear a beep.
4. Step 4: With "CR.d3" displayed, rotate the instrument 180° (keeping it in the vertical position). Press the H/% key to confirm. The screen will display "CR.d4" and you will hear a beep.
5. Step 5: With "CR.d4" displayed, lay the back of the meter flat on the surface (screen facing up). Ensure the buttons are suspended to keep it level. Press the H/% key to confirm. The screen will display "CR.d5" and you will hear a beep.
6. Step 6: With "CR.d5" displayed, flip the instrument 180° (screen facing downward) and place it flat. Press the H/% key to confirm. The screen will display "CR.d6" and you will hear a beep.
7. Step 7: After "CR.d6" flashes and beeps, press the H/% key to confirm. The display will show "CR.d" and calibration will be automatically completed after 3 seconds.

8. Maintenance

• Keep the device clean and dry. Wipe with a soft, damp cloth; do not use abrasive cleaners or solvents.
• Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid dropping or subjecting the device to strong impacts, as this can affect its accuracy.
• Charge the battery regularly, even if not in frequent use, to maintain battery health.

9. Troubleshooting

• Device does not turn on: Ensure the battery is charged. If the battery is low, connect the Type-C charging cable.
• Inaccurate readings: Perform a calibration as described in Section 7. Ensure the measurement surface is stable and free from vibrations.
• "Err" displayed on screen: This typically indicates a calibration error or an internal issue. Try recalibrating the device. If the error persists, contact customer support.
• Screen not rotating: Check if the device is being held steadily. The auto-rotate function requires movement to detect orientation changes.

10. Specifications

Note: Parameters are for reference only; the actual measurements of the specific equipment shall prevail.

11. User Tips

• For best accuracy, always ensure the surface you are measuring from is clean and stable.
• When using the magnetic base, ensure it is firmly attached to prevent slippage, especially on vertical surfaces.
• Regularly check the battery level to avoid interruptions during critical measurements.
• If working in dimly lit areas, the backlit display can be a significant advantage for clear readings.
