Distance issues that need to be paid attention to when using a handheld radar speedometer

When using a handheld radar speedometer, you need to pay attention to the measurement distance. For measuring the speed of motor vehicles such as cars and motorcycles, handheld radar speedometers can usually accurately measure within a distance of about 400 meters. However, when measuring railway vehicles, a longer distance is required. This is because railway vehicles have higher speeds and greater kinetic energy when traveling, and safety issues are more prominent.

The distance required when measuring railway vehicles

When measuring railway vehicles, factors such as different types of vehicles and the speed of the vehicles need to be taken into account. According to the regulations of China Railway Corporation, the following distances need to be maintained when measuring railway vehicles:

1. For passenger cars and freight cars with a speed of less than 40 kilometers per hour, it is necessary to measure at least 500 meters away from the railway track.

2. For passenger cars and freight cars with a speed of more than 40 kilometers per hour but not more than 120 kilometers per hour, it is necessary to measure at least 1,000 meters away from the railway track.

3. For passenger cars and trucks with a speed of more than 120 kilometers per hour, it is necessary to measure at least 1,500 meters away from the railway track.

It should be noted that these distance limits are based on factors such as personal safety and equipment damage. All personnel using handheld radar speedometers must abide by relevant laws and regulations to ensure their own safety and the integrity of the equipment.

Precautions for the use of handheld radar speedometers

When using handheld radar speedometers, you need to pay attention to the following matters:

1. Handheld radar speedometers must comply with national mandatory standards and must pass relevant tests and inspections.

2. Handheld radar speedometers must be calibrated before use.

3. When measuring, you must maintain a stable and stable state.

4. When measuring railway vehicles, you must comply with relevant laws and regulations and maintain a sufficient measurement distance.

5. During use, you need to pay attention to avoid electromagnetic interference and avoid sharing power with other electronic devices.

Conclusion

When using a handheld radar speedometer, you need to pay attention to the measurement distance and precautions for use. When measuring railway vehicles, a sufficient distance must be maintained and relevant laws and regulations must be observed to ensure personal safety and the integrity of equipment.
