How do you take blood pressure with a blood pressure monitor? - pressure monitor

I am now with my grandmother, and they need your blood pressure. It has a target blood pressure model, manual inflation. I intend it, and I think I do it all, but someone could tell me how? You can not tell me because she is very sleepy. It has read more than one screen, but I pump and he deflates. Thanks in advance!
