SELF TEST SCREEN
As part of the start up procedure, it is recommended that a Self Test be performed on the
6300-M3. Before performing the Self Test you must follow the start up procedure explained in
section 3.1. The Main Operating Screen must be displayed on the Remote unit. There should
be no errors displayed on line 4 of the display. If there are errors on line 4 of the display,
press CANCEL to clear each error as it appears, until line 4 is clear.
Now press NEXT SCREEN twice. The display will show the screen shown below.
SELF TESTS
Please vent Pitot and Static ports
to ambient, then press “GO”
There are seven tests performed on the system. These tests check every subsystem for
acceptable operation. If a malfunction is detected in any part of a subsystem, that subsystem
is flagged as defective. Once a defective subsystem is detected, the self test function is
aborted. Therefore, if more than one subsystem is defective, the first defective subsystem will
cause the tests to abort, thereby preventing the user from detecting the flaws in the other
malfunctioning subsystems.
The tests are performed on the following subsystems:
1.
System ROM.
2.
System RAM.
3.
Ps pressure measurement system
4.
Pt pressure measurement system
5.
Pressure and Vacuum pump assembly
6.
Ps pressure control system
7.
Pt pressure control system.
To start the Self Test, please make sure that the Pitot and Static outputs are open to ambient,
and then press GO. The status of each test will be displayed on the screen as shown below.
ROM OK
RAM OK
Ps measurement system OK
Pt measurement system OK
