[Electronic Weight Scale Calibration] How to adjust the electronic weight scale if the human health scale is inaccurate

1. The working principle of electronic scales

Using a force sensor, after placing a heavy object on the platform, the surface is deformed and the shape of the built-in resistance is triggered Change, the deformation of the resistance will inevitably lead to the change of the resistance value of the resistance, and the change of the resistance value of the resistance will change the internal current to generate the corresponding electrical signal, and the electrical signal will become a visible number after processing.

Second, how to calibrate electronic scales

It is difficult to calibrate electronic scales. Unlike general electronic pricing scales and bench scales, it can be calibrated by placing dozens of kilograms of French yards. A normal weight scale calibration requires a 150kg gauge, and the process of putting on and taking off the gauge should be completed within a few seconds. Therefore, the general place is that there is no ability to calibrate the electronic scale, and it can only be returned to the factory. The manufacturer has a specially calibrated machine.

3. Precautions for electronic weighing scales

1. People are not allowed to turn on the scale body by hand. Wait for one minute to automatically shut down and then restart to use, or remove the battery, and re-install the battery according to the correct method of use.

2. There is a toggle switch at the bottom of the scale. The measurement unit can be selected as kilogram or pound. The kilogram will display “kg”, and the pound will display “lb”.

3. When “O-LD” is displayed, it means overload, that is, the weight has exceeded 150kg. When the person steps off the scale surface when overloaded, the scale can resume normal work, and the “O-LD” will also disappear automatically.

4. When the LCD displays “LO”, it means that the battery voltage is too low, please replace it with a new battery immediately and continue to use it. The measurement accuracy of the instrument is not guaranteed in the low-power state.

5. If it is not used for a long time, please take out the battery in time to prevent the leakage of electrolyte from corroding the scale body and the components in the scale.

6. The electronic scale is a precise electronic weighing instrument. It should be carefully stored and used correctly to avoid moisture, drop collision, heavy pressure and exposure to the sun. Do not rinse directly with water. If the surface is dirty, please use a soft cloth to clean it with clean water. It is strictly forbidden to use benzene, nitro-based solutions or liquid caustic soda to clean.

7. When carrying and transporting, it must be handled with care, and the shell will be easily damaged by external force.

Fourth, in order to ensure the measurement accuracy, please follow the following two points during operation

1. When using, place the scale on a flat and hard ground, and there is no sundries under the scale.

2. When weighing, the person should stand upright in the middle of the scale surface, and the body should not shake.
