The function is getting stronger and stronger, so the scope of use is more and more extensive. We are specialized in the production and sales of Jiangsu Hengfeng Weighing Apparatus Co., Ltd.

For many years, we have also accumulated many years of production technology. Today, Hengfeng Xiaobian will tell you about some related knowledge about electronic crane scales. For example, it is very important to check the “faults” of electronic crane scales. Let's learn together with Xiaobian:

First of all, you must have certain knowledge of electronic technology and digital circuits. Before you start maintenance, you should first understand the fault phenomenon and usage of the user. For example, to understand the use of the electronic crane scale, the environmental conditions, the presence or absence of overweight phenomenon, the scale body, the instrument with or without collision phenomenon, first in accordance with the normal use of the method, the scale is in a live working state (the scale body can not be hung on the crane).

1. Check whether the instrument part of the scale body has abnormal noise, whether there is alarm sound, whether the alarm sound interval is regular or not.

2, the scale body or instrument with or without abnormal smell, such as transformers, plastic wires, printed boards, etc. due to circuit heating, burnout, etc. may cause a large abnormal smell.

3. Look at the display status of the weighing display, whether the appearance is damaged, whether the components are broken or not.

4. Touch the integrated chip and electronic components, and feel that the temperature is too high. The suspicious components can be replaced once by the good device. This method is especially effective for the fault phenomenon of the whole machine.

5. Whether the function of operating the electronic crane scale is normal, whether the button is flexible, can be combined with listening and watching, and at the same time, can quickly narrow down the scope of the fault search and lay the foundation for the next step.
