6300 Rev H User's Manual
Caution:
This valve should not be tightened at all past its stop. It seals before it hits the stop. Even
finger-tight beyond the stop may damage the seat of the valve, causing it to leak constantly.

Emergency Vent-Valve, "Static Vent":
In the event that the 6300 is in-operable due to a malfunction or due to loss of power, it is possible to vent the
Static system manually. This is done using the metering valve labeled "Static Vent". This valve is a positive
shut-off valve. Opening this valve slowly will vent the Static output of the 6300 to ambient pressure.
While venting, care must be taken not to exceed the maximum value of the Climb indicator in the aircraft.
Also, before venting the Static system to ambient, the Cross-bleed valve must be opened to ensure that
airspeed is zero.
Caution:
This valve is for emergency use only and should not be used during normal operation. When
emergency venting is completed, this valve should be closed immediately.
Caution:
This valve should not be tightened at all past its stop. It seals before it hits the stop. Even
finger-tight beyond the stop may damage the seat of the valve, causing it to leak constantly.

Static port :
The Static port of the tester is provided with a #4-AN fitting. This port must be connected through a hose to
the Static port of the aircraft. The hose must be connected after performing the Self Test on the 6300. The
hose, once connected, must not be disconnected while the aircraft Static system is not at "Ground" level.
Caution:
Do not connect the Static hose to the Static port before performing the Self Test.
Caution:
Do not disconnect the Static hose from the Static port unless the aircraft Static system is at
"Ground" level and the tester has been turned Off.

Pitot port :
The Pitot port of the tester is provided with a #4-AN fitting. This port must be connected through a hose to
the Pitot port of the aircraft. The hose must be connected after performing the Self Test on the 6300. The
hose, once connected, must not be disconnected while the aircraft Pitot system is not at "Ground" level.
Caution:
Do not connect the Pitot hose to the Pitot port before performing the Self Test.
Caution:
Do not disconnect the Pitot hose from the Pitot port unless the aircraft Pitot system is at
"Ground" level and the the tester has been turned Off.
