2. Power On/Off
Press the ON/OFF button to turn the device on. To turn it off, press and hold the ON/OFF button for a few seconds.
3. Initial Calibration
For optimal accuracy, it is recommended to perform an initial calibration. Place the device on a flat, level surface. Press and hold the ZERO button until "CAL" appears on the display. Follow the on-screen prompts to complete the calibration process. The device will display "PASS" upon successful calibration.
Operating Instructions
1. Basic Angle Measurement
Place the device on the surface you wish to measure. The digital display will show the angle in degrees. The display automatically inverts for easy reading when the device is upside down.

2. Zeroing Function
To set a relative zero point, place the device on your desired reference surface and press the ZERO button. The display will show 0.00°, and subsequent measurements will be relative to this new zero point.
3. Hold Function
To hold the current measurement on the display, press the HOLD button. The reading will freeze, allowing you to move the device and record the value. Press HOLD again to release.
4. Laser Function
The device features dual-sided lasers for precise alignment. With the unit powered on, press the ON/OFF button repeatedly to cycle through laser modes:
- 1st Press: Right laser activates.
- 2nd Press: Left laser activates (right laser turns off).
- 3rd Press: Both right and left lasers activate.
- 4th Press: Both lasers turn off.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the device in its provided carry bag in a dry, stable environment.
- Environmental Factors: Avoid exposing the device to extreme temperatures, high humidity, or strong magnetic fields, as these can affect accuracy.
- Recalibration: If you suspect inaccuracies, perform the calibration procedure described in the "Setup" section.
Troubleshooting
- "Err" Display: This usually indicates the device is not stable or is being moved during measurement. Ensure the device is placed on a stable surface.
- Inaccurate Measurements:
- Check for calibration errors. Recalibrate the device if necessary.
- Ensure the device is not exposed to extreme temperatures, high humidity, or nearby strong magnetic fields.
- Verify battery power. Low battery can affect measurement accuracy.
- Ensure proper positioning and alignment during measurement.
- Protractor Not Working: Check the battery condition. If the battery is low, recharge the device. If the issue persists, try resetting the device by turning it off and on again.
- Laser Issues: If the laser beam appears weak, misaligned, or fluctuates, ensure the device is fully charged and not exposed to environmental interference. Consult manufacturer guidelines for further assistance if problems persist.
