6300 Rev H User's Manual
This function is typically used in two situations. First, just after connecting to the aircraft when the user
wants to put the 6300 into Control mode and control at "Ground" before proceeding further. Second,
when all tests on the aircraft are completed and the user wants to ensure that the outputs are close to
"Ground" before disconnecting the tester from the aircraft.
Note: This function does NOT alter the Pitot-Rate or Static Rate target values. Also, it does NOT alter
the Pitot or Static units.
The 6300 has an internal sensor which is always measuring the ambient pressure. This measurement of
the ambient-pressure is used to establish the "Ground" target value.
When
GND
is pressed, the Lower section of the screen appears as below.
Pressing
GO
will activate the 6300 to perform the operations described above.

HOLD FUNCTION
This function needs to be used only if the user wants to "Pause" while the 6300 is ramping from one
target to another. This function is valid only when one or both outputs are in Control mode. When the
HOLD
key is pressed, the 6300 will stop ramping both outputs and try to maintain a zero Pitot-Rate and
Static-Rate.
The Lower section will display the following message:
Output(s) are on "Hold". Press
In the Upper section, all four target values will be blinking. The Actual values will stop ramping towards
the targets.
Note: The target values are not altered during "HOLD".
To release "HOLD", press GO. The target values will stop blinking and the outputs will start ramping
once more towards their targets.
It is meaningless to use Hold when the outputs are already at their targets and not ramping.
