Ningbo, looking for professional maintenance of injection molding machine.

The working principle of electronic ruler is to change the resistance value of electronic ruler through displacement, so as to output different voltages. From the analysis of your problem description, there are three possibilities: 1 electronic is broken, 2 electronic ruler has no voltage output for other reasons, and 3 controller is broken.

Since both colleagues of the electronic ruler have failed, we can rule out the failure of the electronic ruler, because it is very unlikely that both electronic rulers will fail at the same time. The second possibility is also not available.

The problem must be the common part of two electronic rulers. So it can basically be judged that it is a controller problem. You need to find a professional. Please visit my website when you have time. There are some materials suitable for you to study. www.immp.cn
