1. The telescopic rod is made of aviation aluminum. It can be extended and retracted smoothly and is convenient for storage. 
2. It is equipped with a voice announcement function featuring high-definition simulation. The function can be controlled by a switch.
3. With just one measurement, it is capable of recording a comprehensive set of 12 physical data items.
4. It is equipped with an LED high-definition night vision large screen display, enabling clear readings even in the evening.
5. An ultrasonic probe is employed for height measurement. It has a sensitive response, higher precision, and the error is ≤ 1MM.

Precautions
1.Stable Placement of the Device: The height and weight scale should be placed on a firm and level surface.It is essential to avoid placing it on carpets,soft cushions,or other uneven surfaces, as this will result in inaccurate measurements.
2.Pre-measurement Preparations
• Measured on an Empty Stomach: For the most accurate results,it is recommended to conduct the measurement in the morning,immediately after waking up,while maintaining an empty stomach and having emptied the bladder.
• Removal of Footwear and Heavy Clothing: During the measurement process,individuals should remove shoes,socks,and heavy outer garments,wearing only lightweight clothing.
• Device Inspection: Before measurement,ensure that the display screen of the device reads zero and that all sensors and mechanical components are operating correctly.
3.Correct Measurement Postures
• Height Measurement
• Stand barefoot with both feet together,keeping the back firmly against the measuring rod.
• Maintain a straight head position,with the eyes looking directly ahead,and the top of the head in contact with the sliding scale.
• Avoid any excessive forward or backward tilting of the head.
• Weight Measurement
• Stand evenly centered on the scale surface with both feet,ensuring the body is in a balanced state.
• Refrain from any body swaying or leaning on external objects.
4.Regular Device Calibration
Over time,the sensors of electronic height and weight scales may experience deviations due to extended use or environmental fluctuations.Regular calibration of the device is necessary to uphold the accuracy of measurements.
5.Overload Prevention
Exceeding the maximum weight capacity specified for the device not only risks damaging the equipment but can also lead to inaccurate measurement outcomes.
6.Avoidance of Extreme Environments
Operating the device in extreme conditions,such as high temperatures,high humidity,or low temperatures,may have an adverse impact on the accuracy and operational lifespan of the equipment.
7.Slipping Prevention
During the measurement process,ensure that the area underfoot is free from water stains or slippery objects to prevent accidental slips and falls.
• Use by Children and Elderly: When children or the elderly use the device,adult supervision is advisable to prevent falls caused by poor balance.
8.Cleaning and Maintenance
Clean the surface of the device using a soft cloth.Refrain from using corrosive cleaning agents.Regular cleaning helps prevent dust and dirt accumulation,which could potentially affect the measurement accuracy.
9.Avoidance of Vigorous Movements
During measurement,maintain a stationary stance.Avoid any vigorous movements or jumping on the scale,as such actions may cause damage to the device and compromise the accuracy of the measurement results.
