Typical Use - Laversab 6300-M3 User Manual

This section assumes that the user has read Section 3 and understood the functioning of the
6300-M3. Please do not follow the sequence shown below without first reading Section 3.
The following steps show a typical use of the 6300-M3 for checking aircraft instruments.
1. Turn on the 6300-M3 and check the leak-timers by putting both Pitot and Static outputs
simultaneously into Leak mode. This will take you into the Timed-Leak Screen. Adjust
the leak-timers if necessary, then return to the Main screen by pressing CANCEL
2. Perform the Self Test (NEXT SCREEN twice). Hoses should be disconnected and at
least one Pitot and one Static port must be open to ambient. Pitot and Static Vent valves
must be closed.
3. With ports still open to ambient, Set Ground (Function 7)
4. Connect hoses between the 6300-M3 outputs and the aircraft. Plug all unused Pitot and
Static ports on the aircraft and on the 6300-M3.
5. Select Function 8: Go To Ground. This will put both Pitot and Static into Control mode
with targets of 20 knots and 185 feet (assuming your "Ground" was 185 ft.). Wait for
the targets to be achieved.
6. Set the Pitot target to 200 knots and GO.
7. When Pitot achieves 200 knots, put ONLY Pitot into Leak mode, leave Static in Control
mode.
8. If Pitot has a significant leak (more than 5 knots/min.) then first try and find the leak
while the 6300-M3 is in the Leak screen. If you lose all airspeed while searching for the
leak, cancel out of the Leak screen and go back to Step 7 and continue to search for the
leak. If you need to disconnect ANY hoses on the aircraft or between the 6300-M3 and
the aircraft, then
a. Go To Ground
b. Put BOTH Pitot and Static in Measure mode.
c. Then disconnect hoses.
9. Only after the Pitot system is reasonably leak-tight, should you proceed to the next step.
10. Leave the Pitot target at 200 knots and set the Static target to 3000 feet above Ground.
Both Pitot and Static outputs should be in CONTROL mode. Press GO.
11. When both Pitot and Static targets have been achieved, put ONLY Static into LEAK
mode, leaving Pitot in CONTROL mode.
12. If the Static port has a significant leak (more than 100 feet/min.) then first try and find
the leak while the 6300-M3 is in the Leak screen. If you lose significant altitude while
searching for the leak, cancel out of the Leak screen and go back to Step 11 and continue
