Button Functions:

• Power Button (On/Off): Press to turn the device on or off.
• Unit Button (°, %, mm/m): Cycles through measurement units: degrees (°), percentage (%), and millimeters per meter (mm/m).
• Reference Button: Sets the current angle as a reference (0°) for relative measurements.
• Calibrate Button: Initiates the calibration process for accurate readings.
• Hold Button: Freezes the current reading on the display.
• Buzzer/Backlight Button: Toggles the backlight on/off and may control an audible alert.

5. Operation

5.1 Powering On/Off

Press the Power Button once to turn the device on. Press and hold the Power Button for a few seconds to turn it off.

5.2 Changing Measurement Units

After powering on, press the Unit Button repeatedly to cycle through the available measurement units: degrees (°), percentage (%), and millimeters per meter (mm/m). The selected unit will be displayed on the LCD screen.

5.3 Calibration

For optimal accuracy, it is recommended to calibrate the device periodically or if you suspect inaccurate readings.

1. Place the digital level on a flat, stable surface.
2. Press the Calibrate Button. The display may show a calibration indicator.
3. Follow the on-screen prompts, which typically involve rotating the level 180 degrees and pressing the calibrate button again.
4. Once calibration is complete, the device will return to normal measurement mode.

5.4 Setting a Reference Angle

To measure relative angles from a specific surface:

1. Place the digital level on the desired reference surface.
2. Press the Reference Button. The display will show '0.0°' or 'REF', indicating that this angle is now the new zero point.
3. Move the level to the surface you wish to measure. The display will show the angle relative to your set reference.
4. To clear the reference, press the Reference Button again.

5.5 Using the Hold Function

Press the Hold Button to freeze the current measurement on the LCD display. This is useful when taking readings in difficult-to-view positions. Press the Hold Button again to release the reading and return to live measurement.

5.6 Backlight Control

Press the Buzzer/Backlight Button to turn the LCD backlight on or off, improving visibility in low-light conditions.

5.7 Using the Bubble Vials

In addition to the digital display, the inclinometer features traditional bubble vials for quick visual leveling. Ensure the bubble is centered between the lines for a perfectly level or plumb surface.

7. Maintenance and Care

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing.
• Storage: Store the digital level in a dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.
• Handling: Avoid dropping the device or subjecting it to strong impacts, which could affect its accuracy and functionality.

8. Troubleshooting

• Device does not power on: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
• Inaccurate readings: Perform a calibration as described in Section 5.3. Ensure the surface you are measuring is stable and free from vibrations.
• Display is dim or flickering: Replace the batteries. If the issue persists, contact customer support.
• Buttons are unresponsive: Ensure the device is not in 'Hold' mode. If unresponsive, try removing and reinserting the batteries to reset the device.
