1. There are many components on the main circuit board of electronic scale, and many faults may be caused by components from Precision Balance Supplier pin disconnection/collision and component burnout. Therefore, in the electronic balance failure, can first intuitively through seeing, hearing, smell, touch and other senses on the circuit board inspection. In addition, this method is also effective for some mechanical faults.
2. Through the electronic balance circuit component pin working voltage measurement and normal value comparison, the voltage value is too large, it is caused by the abnormal components.
3. Through a part of the circuit short circuit, and then use oscilloscope or multimeter test results to determine the fault point.
4. The fault point can be determined by disconnecting a part of the circuit and then measuring the resistance, voltage and current with a multimeter.
5.With the help of instruments, will be a good electronic balance and bad electronic balance with the same conditions and parts of the test comparison, the difference is often the fault point.
6. General maintenance of electronic balance, need to prepare some sensors, power supply, circuit board, keyboard and other parts, if some parts are suspected of damage, then use the prepared parts to replace, and then observe whether the results are normal, if normal is the replacement of the right.
7. There is a failure of the electronic scale system, some electronic scales from Precision Balance Manufacturer have self-test function, so the use of the system's own self-test function is also a method.
8. According to the characteristics of the fault of the electronic scale fault range subsection inspection, until the fault is found.
