Tips: How to use laser ultrasonic distance meter correctly?

1. Laser ultrasonic distance meter tests the distance between the obstacle and the bottom of the machine, not the distance from the top. If you take the top as the benchmark, you will find that the displayed distance and the actual distance will have an error of about ten centimeters.
2. When measuring, keep the body and the wall as vertical as possible, especially when the measured distance is farther, the more vertical, the higher the accuracy of the measurement data, otherwise the greater the slope, the greater the error. When measuring long distances, it is recommended to turn on the laser positioning to keep it as vertical as possible.
3. Some curtains can absorb sound waves, causing inaccurate measurement by the ultrasonic distance measuring tool. If you are measuring in a room with curtains, please put the curtain on the other side of the window first, and then close the window.
4. If there is an obstacle in the measured distance, the data measured by ultrasonic is incorrect. For example, tables, chairs or other obstacles. If you are not sure whether your measurement is correct, then you take multiple measurements from different angles.
5. If you need to measure uneven ground or very narrow corners, the data will be wrong. If the distance to be measured is greater than 60 feet (18.288 meters), stand in the center of the house, that is, measure from the midpoint to each side, and then summarize the data.
