How to repair and disassemble the electronic scale, how to repair the broken electronic scale of the

Many people have bought smart scales as instruments for measuring health at home, proving that smart hardware is getting better and better to use and is suitable for most people's life needs.

But when it comes to maintenance, it's not as simple as removing the screws and patting the scale.

Turn on step-by-step reading mode.

Tool Material: Smart Scale.

Cotton swab. White vinegar.

Sandpaper. Screwdriver. How it works:

Dismantle! Turn on the scale.

In order to better understand the smart scale, violent disassembly is essential! Looking at the overall layout, the workmanship of the whole interior is quite solid. The cables are fixed through some cable holes, and the inside looks neat.

If there is a weight deviation on the scale:

Look for this G Sensor. With Sensor On, the sensor allows the smart scale to adjust the gravity range without deviation due to long use. Once you find that the sensor does not work, you can plug in the cable tightly, if it doesn't work, then take out the sensor, place it separately, and then reinstall it.

If the wifi connection is wrong:

Please aim for the green PCB board. The PCB board doesn't feel too advanced, but the circuit connection and overall design are still relatively passable, and there will be no line crossing or swinging factors.

Turn the screws that fix the motherboard, there is a wifi module on the back of the motherboard, if you can't connect to the network due to poor contact, you can stain the cotton swab with white vinegar and wipe the rust, and the bright new cable interface will give you a chance to return to the network.

If the display is broken:

In a bumpy life, it is possible to accidentally break the display. The LED display with red letters on a black background is unexpectedly bright enough, and at the same time, it is unexpectedly easy to be injured. In case the screen explodes inadvertently, and you want to change to other displays, you can cut the connecting wire above, and replace it with other LED data interfaces, and you will have a self-made LED screen.

Combine! Put things back in.

Many people ask the ingenuity of the installation of the smart scale, for the fully sealed scale, the force is not enough, and it is also necessary to use the "slot" screwdriver to help press the edge position, otherwise it is difficult to install it.

Smart electronic scales like Xiaomi and Lexin.

One of the biggest features is the built-in display screen, which can reflect the weight data at the top of the screen. In addition, it can also feedback some faults to the screen, according to the feedback information, the scale can be repaired in minutes, and the service life is extended again. Let's share it with you.

Turn on step-by-step reading mode.

Tool material: smart weight scale, cotton swab, white vinegar, sandpaper, screwdriver. How it works:

First disassemble the scale to understand its structure and the direction of the line, the wire will be fixed through some cable holes, the inside looks relatively tidy, for fear of confusion, you can mark the line.

The scale should be placed horizontally on the floor, but if the scale is high on one side and low on the other, or if there is an elevation angle to the horizontal plane.

It can also lead to inaccurate weighing. Before the electronic scale leaves the factory, it passes through the calibration machine on the water platform, and when the customer uses it on the uneven or uneven table, the weighing will be inaccurate. It is best to use it on a relatively flat or level table, and recalibrate the machine in this position, so as to avoid the problem of inaccurate weighing due to uneven table.

In addition, the scale should be placed on a flat and hard ground when used, and there should be no debris under the scale.

If there is a problem with the WiFi connection, you can put the PCB board on the back of the motherboard.

Take a cotton swab stained with white vinegar and wipe the rust so that you can reconnect to the wifi.

If the display shows "--The scale will have a certain limit, and if it is exceeded, it cannot be measured." But generally speaking, this value is impossible for normal people to reach, probably to about 300 catties. What if it's not that heavy, but the scale shows that feedback as well?

You can try to remove the scale battery and place it upside down for a period of time to solve the problem.

Finally, reinstall the scale, and use a flathead screwdriver to press the edge position, and the scale can be installed.

The electronic scale is an intelligent weight measuring instrument, which has the advantages of high measurement accuracy, lockable display, and convenient reading compared with the traditional pointer scale. For non-zero, inaccurate weighing, inability to turn on, poor display, poor buttons, inability to scale to full load, battery inability to store electricity, etc. are all simple faults of electronic scales, how to repair them? Let's take a look at the electronic scale fault repair and health scale repair guide!

c. If it cannot be compensated, please check whether the sensor is defective. (Please follow item 8 for testing).

dPlease follow the instructions in the manual to make weight correction.

2. The weighing is not accurate.

A Observe whether the internal code value is stable, whether there is friction in each part of the sensor, whether the regulated power supply is stable, whether the op amp circuit is normal, whether there is foreign matter in the line version of the A D circuit, and whether the feedback resistance, capacitance, and filter capacitor are bad or leakage.

bCheck whether the output signal value of the sensor is within the standard.

c is not included in the standard, please refer to item 10 for compensation.

d. Use weights to test whether the weighing pan and four-legged weighing are average. (If it is uneven, please refer to item 9 for grinding).

Please follow the instructions in the manual to make weight corrections.

1. The electronic scale display will not be displayed if there is no response after it is turned on.

Maintenance method: first inspection.

Check whether the power link is normal, check whether other keys can be used, if it is normal, then the eight achievements are that the display is damaged, then you can contact the first business technician, let it be replaced;

2. The weighing is not accurate.

Maintenance method: a. Check whether the position is correct, whether the limiting device is in the correct position, and whether there are debris under the weighing platform against the weighing platform;

b. If everything is normal in the previous step, you need to check whether the junction box is well wired, check whether the angle difference is consistent and whether the instrument setting is correct, and finally replace the sensor.

3. The electronic scale will also alarm if it is not overweight.

Maintenance method: When this situation occurs again, the operator should first check whether there is a problem with the product setting, what is the maximum range setting, and whether it is consistent with the range of the electronic scale itself. If everything is normal, you need to seek the help of the technical staff of the first business.

Precautions for the use of Xiangshan electronic scales:

1. It is strictly forbidden to wash in the rain or with water, if it is accidentally wet, wipe it with a dry cloth, and send it for repair as soon as possible when the machine function is not normal.

Solution: 1) Bad keys.

2) Bad key socket.

3) For the above reasons, it is recommended to send it back for after-sales processing.

Prior to this, there was no standard and precision that could measure body weight. In Egypt, scales date back to about 1878 BC, but their use may have extended much earlier.

The weight scale in the real modern sense was improved and invented by Leonardo da Vinci, with the development of the electronic scale industry, slowly many brands entered the Chinese market, electronic scales are used by more people, and more and more electronic scale brands are familiar to humans.

If it's "lo", it must be a low battery. Replace the battery with the same specification as soon as possible.

If it's "OL", there may be a problem with the weighing circuit. For example, the sensor is damaged!

Unscrew the screws and replace the battery.

See if there are any screws, and if there are, you can repair and disassemble them.

The battery back cover of your electronic scale can be opened and the battery shrapnel can be scrubbed with alcohol.

If it doesn't show up after changing the battery first, you can open the battery back cover of your electronic scale and scrub the battery shrapnel with alcohol. If it still doesn't work, you can open the back cover with a screwdriver yourself to see if the cord of the battery is broken, and if the rust is broken, just pick it up. The best words,See if the screws at the bottom of the display screen are loose,If the screws are loose, they won't be displayed.,After tightening the screws, the general display problem will be ruled out.。

Introduction of electronic scales

Electronic balance is a type of scale. The scale is a tool that uses Hooke's law or the lever balance principle of force to determine the mass of an object, which can be divided into three categories: mechanical scales, electronic scales, and electromechanical scales according to the structural principle.

The electronic scale is mainly composed of three parts: load-bearing system (such as weighing pan, weighing body), force transmission system (such as lever force transmission system, sensor) and value indication system (such as dial and electronic display instrument).

When an object is placed on the weighing pan, pressure is applied to the sensor, which undergoes an elastic deformation, which changes the impedance, and at the same time outputs a varying analog signal using a change in the excitation voltage. The signal is amplified by an amplification circuit and output to an analog-to-digital converter. Convert into a digital signal for easy processing and output to CPU operation control.

The CPU outputs this result to the display based on key commands as well as programs. until this result is displayed.

Hello, I'm glad to answer for you: The maintenance methods of the human body electronic scale are as follows: 1. The electronic scale display does not respond after turning on and does not display the maintenance method:

First of all, check whether the power link is normal, check whether other keys can be used, if it is normal, then the eight achievements are that the display is damaged, then you can contact the first business technician, let it be replaced; 2. Maintenance method for inaccurate weighing: a. Check whether the position is correct, whether the limiting device is in the correct position, and whether there are debris under the weighing platform against the weighing platform; b. If the previous step is normal, you need to check whether the junction box is well wired, check whether the angle difference is - and whether the instrument setting is correct, and finally replace the sensor. 3. The electronic scale is not overweight and will also alarm the maintenance method:

When this situation occurs again, the operator should first check whether there is a problem with the product setting, what is the maximum range setting, and whether it is consistent with the range of the scale itself. If it is normal, you need to seek the help of the technical staff of the first business. Hope it helps.
