1. Turn the adjustment screw slightly to "-"
-direction. Orifice pressure must drop immediately.
If this does not happen, you must readjust the

a decrease or increase in the nozzle pressure is
noticeable on the measuring instrument when the
adjustment screw is turned slightly to "+" or "-"
direction.
2. Close test nipple after the measurement!
3. Remove the measuring instrument and check if the
test nipple is gastight.
