Common electronic platform scale malfunction problems and solutions:

1. No display or sound when turned on: From the circuit analysis, "no display" is a fault in the display circuit, and no sound is a fault in the buzzer circuit. The probability of these two faults occurring simultaneously is very low. So generally, faults occur in the power supply circuit.

2. Inaccurate weighing: Observe whether there is friction in various parts of the sensor, whether the voltage regulator is stable, and whether the operational amplifier circuit is normal. Is there any foreign object on the circuit board of the A/D circuit.

3. Display malfunction: Observe whether there is any malfunction on the normal LCD when turned on. If not, it can be concluded that the LCD is malfunctioning; Check for oxidation, cold soldering, or short circuits on the CPU pins; Check for a short circuit in the circuit between the CPU and LCD.

4. The battery cannot store electricity: first determine the problem caused by the fuse, power switch, and power cord; Check if the transformer has AC110/220 input and AC18V output; Check if the two poles of the PIN accessory inserted into the input terminal of the machine version and transformer are normal; Replace the battery.

5. The electronic scale cannot be charged or the charging indicator light does not measure or respond: Please first confirm whether the 110V/220V voltage switch of the electronic scale is set to the same voltage as the power supply, and make sure that the charging cable is firmly plugged into the charging dock on the scale; Check if there is any external force causing the charging cable to break; Check if the fuse is faulty; Poor battery.

6. The button will automatically trigger if there is no action or the action is abnormal: the button is faulty; Poor button socket.

7. The electronic scale cannot reach full load: the protective screw of the electronic scale has not been removed; Is there any foreign object infiltrating the electronic scale causing interference, impact, or injury from falling; Is the internal program setting of the electronic scale correct.
