2.4 Connecting the Calibration Fixture to the FTK100
This section describes how to connect the calibration fixture to the FTK100 control
module.
The FTK100 supports calibration fixtures designed to test pressures on standard
pitot-static probes and five-hole probes. A calibration fixture designed to test the
five-hole probe integrated into the ARIM320 is shown in Figure 4. For testing the
more common pitot-static probes, tubing is only required to be connected between
the pitot tubing connector on the forward face of the calibration fixture, and the static
tubing connector furthest aft on the side of the calibration fixture. If a five-hole probe
is being tested, as shown in Figure 4, tubing must also be connected to the angle-
of-attack (alpha) connectors in the vertical plane and sideslip connectors in the
horizontal plane. Please note that the calibration five-hole probe calibration fixtures
are typically designed so that the static connector is on the same side as the Alpha+
connector. This allows the user to orient the calibration fixture correctly when
installing it on the probe.
Both the FTK100 control module and Aventech Research Inc. calibration fixtures
utilize 1/8” OD quick connect / disconnect fittings to interface to the interconnecting
pressure tubing. To install the tubing simply insert it as far as possible into the fitting
and it will lock in place. To disconnect, push down on the orange collar on the fitting
and pull the tubing out.
Six lengths of 1/8” OD tubing will have been provided with your field test kit which
should be installed between the pressure connections show on the calibration
fixture in Figure 4 and the labeled input ports on the FTK100 shown in Figure 2.
2.5 Installing the Calibration Fixture
For pitot-static probes, orientation of the calibration fixture is not important however,
for five-hole probes it is critical. As described in Section 2.5, the static pressure
fitting is typically located on the same side as the alpha+ pressure fitting.
Install the calibration fitting onto the measurement boom by sliding it over the boom
while insuring the static pressure fitting is pointing straight up. This will insure that
the remaining pressure fittings are oriented correctly relative to the pressure ports
on the measurement boom. Slide the fixture as far as it will go onto the boom and
then apply a small amount of longitudinal force to the fixture to compress the O-
rings against the nose of the boom and seal off the pressure ports to the calibration
fixture. While applying this force, rotate the collar located at the rear of the
calibration fixture clockwise, when looking at the front of the fixture, gently to lock
the fixture onto the probe boom.

Some calibration fixtures will be manufactured with a clear acrylic front to allow the
user to observe that the pressure inputs in the calibration fixture are correctly
oriented with the pressure ports on the probe.
2.6 Installing the Interface Cable
Install the CAN Interface cable between the FTK100 and Device Under Test (DUT).
2.7 Turning the Unit On
To begin a test both the DUT and the FTK100 have to be turned on in that order. To
power the FTK100 depress and release the power switch shown in Figure 1.
As the unit boots up and runs its internal self-tests the splash screen shown in
Figure 5 below will appear showing the unit`s current firmware version and build
number, manufacturing date and calibration date.

3.1.1 IBIT
The FTK100 will send an IBIT request to the DUT and the 32-bit status word sent
in reply from the DUT will be displayed in hexadecimal format. To assist
interpretation, the output includes text descriptions of each non-zero bit occurring
in the status word, each representing a particular error condition.
Figure 9: Ibit Test
3.1.2 CBIT
CBIT data is continuously generated by the DUT under normal operation. The
FTK100 sends a request at 1Hz to continuously receive and monitor the latest
CBIT values being generated by the system. Two different CBIT values will be
output along with text-based descriptions of all non-zero bits denoting various
error conditions.

3.1.3 Pressure Test
This feature will perform a pressure test of all five pressure ports on the tip of the
air-data probe and the ring of static-pressure ports around its circumference.
This test can be performed only if the appropriate probe adapter is firmly secured
to the DUT and is connected to the FTK using the supplied tubing.
Immediately after the Pressure Test is selected, the internal pump will begin to
pressurize the system to approximately 3000Pa. If any leaks are present, as
would occur if the probe adapter is not properly in place, the pump will continue
to run until a timeout error is generated if the target pressure is not reached
within 6 seconds. If the no leaks occur, the pump will bring the system up to test
pressure in approximately 1 second. The following window will then be displayed:
Figure 11: Pressure Test Layout
After a 5 second settling period, valves will be activated to introduce the test
pressure to the AOA+ (ALPHA+) pressure port. The FTK100 will read the
pressure data sensed by the DUT across the CAN AERO connection and record
data from its own internal reference pressure sensor for a period of five seconds.
After this sampling period, the valves are switched to disconnect the AOA+ port
and return it to ambient atmospheric pressure, and simultaneously connect the
internal pressure plenum to the AOA- (ALPHA-) port. During the following 5
second settling period, the pump is given ability to re-engage and recharge the
plenum if necessary. If this occurs, a further 5s settling period is introduced
before data is collected from both the DUT and reference pressure sensor. This
process continues through all pressure ports in the following order: AOA+, AOA-,
AOS+ (BETA+), AOS- (BETA-), Pitot-Static. After data has been collected for the
pitot-static test, the valves switch to change the direction of air-flo w between the
pump and internal plenum so as to generate a vacuum. The pump runs and
takes the plenum pressure down to approximately 90kPa. The static pressure

port is then activated and now the internal reference barometric sensor is
sampled concurrently with data from the DUT access across the CAN AERO
network connection.
The status bar will display status information as the test progresses through all
stages.
Once the test is complete, mean values are computed from the approximately
150 data points sampled during each stage of the test. Mean values from the
reference sensors, the DUT and the differences between them are displayed in a
tabular format:
