3. Setup

3.1 Battery Installation

The Preciva Digital Angle Finder requires one CR2032 button cell battery (included). To install or replace the battery:

1. Locate the battery compartment cover on the central pivot of the protractor.
2. Rotate the cover counter-clockwise to unlock and remove it.
3. Insert the CR2032 battery with the positive (+) side facing upwards.
4. Replace the cover and rotate it clockwise to lock it securely.

Note: A new CR2032 battery can provide power for over 2000 hours of operation.

4. Operating Instructions

4.1 Power On/Off

• To Power On: Briefly press the ON/OFF button. The LCD display will illuminate.
• To Turn Off LCD (Sleep Mode): Briefly press the ON/OFF button again. The display will turn off, but the system remains active for quick restart.
• To Power Off Completely: Press and hold the ON/OFF button for approximately 3 seconds. The entire system will shut down.

4.2 Zero Function (Absolute/Relative Measurement)

The ZERO button allows you to set a reference point for relative measurements or reset to absolute zero.

• Absolute Measurement: When the device is powered on, it typically displays the absolute angle relative to its initial position.
• Relative Measurement (Zero Reset): To measure an angle relative to a specific surface or position, place the protractor on that surface and press the ZERO button. The display will show 0.0°, and subsequent movements will measure the angle relative to this new zero point.

4.3 Taking Measurements

1. Power on the device and set the zero point as desired (absolute or relative).
2. Position the two blades of the protractor against the surfaces or lines whose angle you wish to measure.
3. Read the angle directly from the LCD display. The display updates in real-time as the blades are moved.

4.4 Locking Function

To lock the blades at a specific angle:

1. Adjust the blades to the desired angle.
2. Rotate the locking screw (located at the pivot point) clockwise until the blades are securely held in place.
3. To unlock, rotate the screw counter-clockwise.

5. Maintenance

• Cleaning: Wipe the tool with a soft, dry cloth after each use. Avoid using abrasive cleaners or solvents that could damage the display or finish.
• Storage: Store the angle finder in a dry place, away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace the CR2032 battery when the display becomes dim or unresponsive. Dispose of used batteries responsibly.
• Calibration: The device is factory calibrated. If you suspect inaccuracies, ensure the blades are fully closed and press the ZERO button to reset.
