YT-1000L electric-pneumatic valve positioner! Help: What do zero adjustment and span adjustment mean? What role does it play! What do DA actions and RA actions mean? When adjusting the zero point, the signal should be set to 4 mA at the start. What does 4 mA represent? I’m a novice operator in a chemical plant control room; I don’t have a mentor. I earnestly ask those who know how to do this to explain it to me. If writing out detailed instructions is too troublesome, you can leave your WeChat address and I’ll contact you. I really hope to get help from those who know the subject!
I want to become a disciple! Where are those who are expert in locators! ! !
Are there any experienced teachers who work with PS polystyrene? I want to learn a skill! ! !
As I understand it, it’s a zero point and a range; that is, the valve opening corresponding to 4 MA and 20 MA

DA represents a positive action, while RA represents a negative action. The 1000L model is of the actuator type; the 1000R model, on the other hand, has an angular travel mechanism. It’s best to read the instructions carefully. For these positioners with a nozzle and baffle structure, you can take the time to disassemble them completely – that way you’ll gradually understand how they work. The electrical positioners made by South Korea’s Yongtai are of high quality when they are original; counterfeit versions, however, often have problems
Supportable; the original brand ones are still okay, but domestic ones are of very poor quality nowadays
Sometimes we learn about positioners, and other times we learn about manufacturing processes. What exactly do you want to learn?
