For tests where accurate absolute pressure measurement is required, i.e. for Static tests
measured in feet, the Operator must enter the Pressure Of The Day (POTD). The PSLT will
automatically recalibrate itself to carry out precision measurement to the point selected.
4. SETUP
CAUTION:
ENSURE THAT THE HOSE FROM THE PSLT IS CONNECTED TO THE
CORRECT AIRCRAFT SYSTEM. FAILURE TO DO SO MAY RESULT IN
DAMAGING PRESSURES BEING APPLIED TO THE SYSTEM UNDER
TEST.
A. Connect the PSLT port to the pitot or static system under test and ensure the connection is
leak tight.
B. Apply power to the PSLT by pressing the PWR key. The system performs an internal self-
diagnostic test routine and the screen displays the version of software installed (
Figure 4
). For
a short time during power up, an initial battery status indicator will be displayed (
Figure 5
),
providing the Operator with an estimate of percentage battery life available (20% to 100% in
20% steps).

Following successful completion of the self-test routine, the screen displays the
first main menu, Menu 1, Leak Test (
Figure 6
). The menu option required is
selected by pressing the SEL key. Pressing once when Menu
1
is displayed calls
up Menu

Pressure Control. Pressing a second time calls up Menu
3,
Setup.
Pressing a third time calls up Menu

again, and so on.
