Why does it have to be calibrated

I have put a new rock shaft in it as the old one was shot and came as a kit as the new shaft is different so had to put the new draft sensor on and it now lifts far too high and will not drop so I'm guessing its because the new sensor doesn't know where it is I can get it to work fine in calibration mode but soon as you take the dia fuse out it won't work. just need to know how to set the high point and the low point
