5. Operating Instructions
Power On/Off
- To Power On: Press the Power ON/Measure Button (1).
- To Power Off: Press the Power OFF/Data Delete Button (4).
Laser Measurement
- Press the Power ON/Measure Button (1) to activate the laser.
- Aim the laser dot at the target surface.
- Press the Power ON/Measure Button (1) again to display the distance on the LCD screen (10).
Tape Measurement
- Pull out the steel tape (6) to the desired length. The tape features a self-locking design to hold its position.
- To retract the tape, press the Tape Retract Button (9).
Unit Conversion
- Press the Measurement Unit Switch Button (3) to cycle through available units: meters (m), inches (in), and feet (ft) for laser measurements.
- The steel tape measure displays units in centimeters (cm) and inches (in).
Measurement Modes
The device supports various measurement modes for different applications:
- Single Measurement Distance: Standard point-to-point distance measurement.
- Continuous Measurement Distance: Measures distance continuously as the device is moved.
- Area Measurement: Measures length and width to calculate area.
- Volume Measurement: Measures length, width, and height to calculate volume.
- Pythagorean Measurement: Uses the Pythagorean theorem to calculate indirect distances (e.g., height of an object).
To switch between these modes, press the Measure Mode Switch Button (2).
Reference Point Selection
The device allows you to select the measurement reference point:
- Front Measuring-Tool Edge: Measurement starts from the front edge of the device.
- Rear Measuring-Tool Edge: Measurement starts from the rear edge of the device.
This is useful when there is an obstruction at the rear, or when the length of the body needs to be automatically added to the measurement. Press the Measure Reference Point Switch Button (part of 2) to toggle between these options.
Data Storage
The device can store up to 20 sets of measurement data. Use the Stored Data View Button (part of 3) to review previously recorded measurements.
Self-Calibration Function
The device features a ±9mm self-calibration function for enhanced accuracy.
6. Charging (for rechargeable versions)
If your model is equipped with a rechargeable battery:
- Recharge the device via the USB Type-C cable (battery included with rechargeable models).

- Clean the laser lens and tape blade regularly for accuracy.
- Store the device in a dry place.
- Always retract the tape fully after use to prevent damage.
8. User Tips
- The device's digital display can show measurements in both metric (m, cm) and imperial (ft, in) units, offering flexibility for different project requirements.
- The combination of laser and tape measurement makes this tool ideal for various tasks, including measuring windows for roller blinds, carpentry, clothing material measurement, mechanical work, and general survey and drawing.
- The magnetic hook on the tape measure allows for easy and secure attachment to metal surfaces, making one-person measurements much simpler.
9. Troubleshooting
- Q: Why is the laser measurement inaccurate?
- A: Ensure the target surface is non-reflective and the laser lens is clean. Avoid direct sunlight interference, which can affect accuracy.
