If the number is not displayed, the machine can't be turned on, and there may be no power. First, check whether the battery of the scale has electricity. If there is no electricity, first charge it with a rechargeable battery electronic scale. Or the kind that uses batteries, go to a store in button cell and buy the same type of batteries. Or consult the merchants who buy home appliances and send electronic scales.
2. Check the voltage
It can be opened, but the weight will not be displayed after opening. Also check the battery voltage of the electronic scale, and be careful to be higher than 6V. If it is lower than 5.7V, please charge it; If it is lower than 4.8V, it will be dead soon after charging. Please replace the battery.
3. Sensors or display instruments
The sensor wire is broken or the sensor is broken. Open the electronic scale to see if the wires inside are connected properly and the wires at the sensor connector are broken. If the wires are good, correct them and try. In addition, if the sensor wire is reconnected, the sensor wire is not connected correctly.
The failure rate of weighing display instrument is very low, which rarely occurs in use, and its circuit is complex and it is difficult to check. For the power supply part, it can be diagnosed by measuring the output voltage. For the main circuit board, the fastest, simplest and easiest method is "replacement method".
That is, the original circuit board is directly replaced with the intact main circuit board, which can quickly judge whether the main circuit board is faulty. As for the maintenance of the main circuit board, like the maintenance of other electronic instruments, its content is more complicated and needs professionals.
Extended data:
use
1, in order to ensure the accuracy of the electronic scale, it is best to test whether the power is sufficient before use;
2. The feet must be balanced to ensure the accuracy of the values;
3. The biggest headache of mechanical health scale is that the pointer will have deviation, which needs to be adjusted frequently to ensure the accuracy of the pointer. It is best to pay attention to the adjustment before use;
4. Shake it a few times before using it.
maintain
1, the electronic scale must be kept well, especially when the battery power is insufficient, it should be replaced in time to avoid oxidation;
2. If it is not used for a long time, take out the battery;
3. Don't bump, it will make the data inaccurate;
Don't set the pointer too fast.
