a. Go To Ground
b. Turn Off the 6300.
c. Then disconnect hoses or adapters.
16. Only after the Static system is reasonably leak-tight (leak less than 100 feet/min) , should you
proceed to the next step.
17. Now that both Pitot and Static systems are reasonably leak-tight, start your checkout procedure for
checking the instruments inside the aircraft. At this point you may want to execute the appropriate
Profile for your test.
Caution: During your tests, do not put either Pitot or Static output in MEASURE mode unless the aircraft
is at “Ground”. Use only the Control and Leak modes.
18. After you finish the last point of your test procedure, press GND to perform the Go-to-Ground
function. The targets will get set to 20 knots and “Ground” altitude.
19. After the targets have been achieved, turn Off the 6300.
20. Disconnect the hoses from the 6300.
During your test procedure, if you lose power, the 6300 will maintain the pressure. When power comes back
on, the 6300 and the aircraft will be at the same pressure as before except for pressure lost due to leaks in the
system.
If the 6300 behaves erratically for whatever reason, turn Off the 6300 using the Power key on the Remote
unit. Turn the unit back On after 30 seconds and attempt to use the 6300 again.
The 6300 is capable of overcoming substantial leaks in the system. It is not capable of overcoming extremely
large leaks. Therefore it is essential that the system be reasonably leak-tight before taking the aircraft to
higher altitude or airspeed.
During a leak-check if the Static leak-rate exceeds the target Static rate, the 6300 will automatically put Static
into Control mode and try to compensate for the leak. Similarly, if the Pitot leak-rate exceeds 50 knots/min,
the 6300 will automatically put Pitot into Control mode. An error message will indicate that a large leak
exists. In such cases, go back to Ground and go through the leak-check process shown above, to find and fix
the leak before proceeding further.
It may be helpful to keep a copy of the procedure, shown in Figure 5.1, with the 6300 to assist the operator
while using the 6300.
