How to distinguish whether there is a problem with the electronic scale circuit

Electronic scales are an electronic scale that we use more and more widely. Everyone can't avoid problems when using electronic scales. Today we take a look at this article on how to distinguish whether there is a problem with the electronic scale circuit. Hope to be helpful to everyone.

How to tell if there is a problem with the electronic scale circuit circuit:

1. Intuitive method. There are many circuit components on the main board of electronic scales. Many problems are caused by short circuit, open circuit, bad contact at the connector, and component welding. Therefore, the first thing to do is to use an intuitive feeling to check, through visual, listening, questioning, touching, etc. Circuit board inspection.

2. Comparison and replacement method. Comparing a good electronic bench scale with a problematic scale can quickly detect problems. And you need to prepare sensors, power supplies and other components, replace the parts that are suspected of being damaged, and then observe whether the results have changed. Comparison and replacement method can accurately determine the problem.

3. Voltage measurement method. By measuring the operating voltage of the circuit element and the chip and comparing it with the normal value, the place where the voltage change is large can be judged as a problem point.

4. Short circuit open circuit method. We are not unfamiliar with short-circuit disconnection. A short-circuit is the short circuit of a certain part of the circuit. Then we use the instrument test to determine the problem. The disconnection is the disconnection of a part of the circuit, and then measured through a multimeter to determine the problem points.

It is still relatively simple to check the problem of electronic scales. I believe that by reading this article on how to distinguish whether there is a problem with the circuit of the electronic scales, in the future there will be such problems as the electronic scales, and we will know how to deal with them.
