Open the Main Menu (
SHIFT
+ 3) and select “Functions” and “EPR”. The EPR Menu will
show, allowing the operator to enter the desired values of the Static Pressure (inlet) and the
target EPR value. Press the yellow button Go when ready. The Status Screen will show the
EPR instead of the airspeed / Qc rate (FIG 18). The EPR and altitude / Ps can be changed
at any time.
To close the EPR visualization, press the square yellow button End.

10.9 MULTIPLE ISOLATOR FUNCTION (OPTION)
The optional Multiple Isolator allows the Operator to close individual pneumatic ports; this
function allows easier leak checking when testing multiple connections, and also permits
the Operator to generate different pressure values behind each port.
10.9.1 BASIC USAGE: LEAK CHECKING ON INDIVIDUAL PORTS
The basic use case of the multiple isolator consists of isolating single ports to identify the
source of a leak, when more than one pneumatic output is connected. In fact, the standard
leak test function (chapter 7.2) permits to detect the presence of a leak, but does not
enable to detect which part of the whole pneumatic circuit is leaking.
By closing each individual port, the Operator can detect which one is leaking, because the
leak rate will immediately decrease after the leaking port is closed.
The lower-right corner summarizes the state of all ports.
Press
SHIFT
+
000
to display the Multiple Isolator Screen (FIG 19). The upper part of the
display shows the state of the output ports for the selected channel. If the altitude/Ps is
selected, the Static ports are displayed; if the airspeed, Pt or Qc are selected, the Pitot
ports are displayed; if the AoA is selected, the AoA ports are displayed.
