indicator should drop to zero.

☛ NOTE: Do not use a tool.
4. Ensure that the unit is set to the “PULSE” position.
5. Slowly open the valve on the oxygen cylinder until the needle in the gauge indicator no
longer moves.
6. Close the cylinder valve again.
7. Observe the needle in the gauge indicator for approximately one minute.
• If the needle remains in its position, everything is OK.
