Answer / ashraf

You need one water manometer,one T fitting and one flexible
rubber hose. Connect the hose,the manometer and the pressure
gauge to the T fitting without any leakage.
Blow air (by mouth)through hose till span (cross check at
water manometer) and fold the rubber hose. Adjust span setting.
Then drop the pressure by unfolding the hose and adjust for
zero.
Repeat process two or three times.
Now check for mid-range, if it is ok, then calibration is over.
