Can the height measuring instrument measure the soles?

The ultrasonic probe used by Shanghe Technology is an ultrasonic sensor imported from the United States, which uses ultrasonic as a detection means to generate and receive ultrasonic waves.

The sensor can determine the height of human body through the wavelength of sound wave, the time difference between transmitting sound wave and receiving return sound wave. While sending the pulse, the timer of the receiver starts and counts until the receiving sensor receives the reflected callback, and the time difference is equivalent to the measured distance, so that the distance from the measuring instrument to the top of the head, that is, the height of the human body, can be calculated.

Ultrasonic measurement is the average value around the top of the head, and it will not reduce the height of shoes, so Xiaohe suggests that everyone try to wear flat shoes or no shoes when measuring to ensure more accurate measurement results.

Matters needing attention in using ultrasonic height and weight measuring instrument;

1, ultrasonic height and weight should be placed in a flat and empty place, and the horizontal adjusting feet should be adjusted to make them stable and not shake.

2. Master the measurement posture requirements of "holding your chest up" and "looking straight ahead".

3. The braids and knots on the top of the head should be loosened (too high a comb will affect the height) and accessories should be removed (light accessories will not affect it).

4. Don't shake your body when measuring (shaking won't lock your height).

5. Before the measurement, the subjects are not allowed to engage in physical activities and physical labor.
