6.2.22 -000
This key performs two functions during numeric entry.
1. If it is the first numeric key pressed, it produces a minus sign for the entry of negative
numbers.
2. If it is a subsequent key pressed during numeric entry it produces three zeros for fast entry
of thousands
Example
To enter -1000:
a. Press -000: (Display shows -)
b. Press 1: (Display shows -1)
c. Press -000: (Display shows -1000)
Note: When -000 is pressed during entry of an aircraft name for limits or in the
Print facility, it always produces “-”.
6.2.23 CLEAR/QUIT
1. During numeric entry, CLEAR/QUIT removes the new number and restores the previously
entered number. Once the ENTER key has been pressed, the old number cannot be restored.
2. When menus are displayed, CLEAR/QUIT exits the menu, generally to the previous display.
3. For those displays containing a [SAVE] option, changes made before pressing CLEAR/QUIT
are ignored. For all other displays, changes are saved when CLEAR/QUIT is pressed.
4. When warning messages are displayed, pressing CLEAR/QUIT removes the message.
6.2.24 ENTER
The ENTER key completes numeric entry.
6.2.25 CLEAR + ENTER (ABORT)
Pressing CLEAR/QUIT and ENTER together, restarts the ADTS 405 from the power-up sequence.
Output valves close immediately and open during the restart sequence. The restart sequence starts
with the display showing:
CAUTION The (ABORT) function should only be used as a last resort:
1. When a restart is required after the system has shutdown displaying an error message.
2. As an emergency measure with a serious problem concerning the aircraft or component
under test.
3. After this restart sequence, the system vents, at a safe rate, both channels (pitot and
static) to atmosphere during the power-up sequence.
