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
After the pump section test has passed successfully, the screen is cleared and the status of the
remaining tests is displayed as shown below.
Pump section OK
Ps control system OK
Pt control system OK. Tests successful.
After the tests have been completed successfully, press the CANCEL key to return to the Main
Operating Screen.
If any of the tests fail, then note the failure, turn OFF the unit and contact the factory.
