Self Test Screen - Laversab 6300-M4 User Manual

When either of these warning messages is displayed, press GO, which will bring up the Main
Operating Screen. At this point it is recommended to go back to GROUND and to Measure
mode on both outputs ad fix the leak before proceeding further.
It is important that each output be put into the Leak mode independently. That is, when
the Pitot system of the aircraft needs to be checked for leaks, only the Pitot output should
be in Leak mode, keeping the Static output in Control mode. When the Static system of the
aircraft needs to be checked for leaks, only the Static output should be in Leak mode,
keeping the Pitot output in Control mode.
Pressing the CANCEL key allows you to exit from the Leak Screen, back to the Main
Operating Screen. If the mode prior to entering the Leak mode was Control then the 6300-M4
will revert back to Control mode on exiting the Leak Screen.
