What is the procedure of DP switch calibration
Answer Posted / rahul
For DP switch calibration first apply zero pressure to low side and gradually increase high side pressure upto dp range. (0 to high) then increase low side pressure upto pressure previously applied on high side ( high to 0). then again increase high side pressure upto dp range (0 to high). then increse low side pressure upto equilizing with high side pressure ( high to 0) . this process will go more than 5 scale to have more accuracy upto maximum operating line pressure.
