ADCS-601-AF is a fully automated reference level Air Data Calibration Standard for the verification and
calibration of air data range instruments, in particular Air Data Test Sets (ADTS). ADCS-601-AF’s intended
function is the static pressure calibration of Pt and Ps range pressure transducers with very low measurement
uncertainty. ADCS-601-AF is not intended to duplicate the functions of an ADTS in calibrating and testing onboard aircraft instruments.
ADCS-601-AF covers the pressure range of 1 to 380 kPa (0.3 to 120 inHg) in absolute and gauge modes
with fully automated operation and state of the art uncertainty.
ADCS-601-AF is an integrated system made up of several instruments that work together under the control of
ADCS Tools software running on a personal computer. Operator interaction with ADCS-601-AF is
accomplished through the keyboard, pointing device and display of the system controller (personal computer).
The heart of the system is a fully automated PG7601 piston gauge or pressure balance that covers the
range of 15 to 380 kPa (4.5 to 120 inHg). The PG7601 range is extended down to 1 kPa (0.3 inHg) by an
FPG8601 force balanced piston gauge with automated pressure control.

ADCS-601-AF is a fully automated reference level Air Data Calibration Standard for the verification and
calibration of air data range instruments, in particular Air Data Test Sets (ADTS). ADCS-601-AF’s
intended function is the static pressure calibration of Pt and Ps range pressure transducers. To this end,
the system automatically sets pressure values with very low measurement uncertainty in the range of 1 to
380 kPa (0.3 to 120 inHg) in absolute and gauge modes. ADCS-601-AF is not intended to duplicate the
functions of an ADTS.
The ADCS-601-AF system is made up of two automated pressure standards with overlapping ranges to
cover the full pressure range. An automated PG7601 piston gauge covers the range of 15 to 380 kPa
(4.5 to 120 inHg) (see Section 2.2.1). The PG7601 range is extended down to 1 kPa (0.3 inHg) by an
FPG8601 force balanced piston gauge with automated pressure control (see Section 2.2.2). The system
also includes vacuum pumps and vacuum measurement instruments to support absolute mode operation.

2.2 PRESSURE STANDARDS
2.2.1 PG7601 PISTON GAUGE
The heart of the ADCS-601-AF Air Data Calibration Standard is a PG7601 gas operated
piston gauge. The PG7601 piston gauge system includes:
- PG7601 piston gauge platform with terminal (on reference bench)
- PC-7600/7100-10, TC 10 kPa/kg piston-cylinder module (mounted in platform)
- MS-AMH-38, 38 kg mass set (installed on platform)
- AMH-38-VAC, automated mass handler (installed on platform)
- CDG-VAC-REF, capacitance diaphragm gauge with display and isolation valve for
measurement of PG7601 reference vacuum in absolute mode (installed on platform)
- PPC3-700K pressure controller to automate PG7601 system pressure control (in
The PG7601 piston gauge, AMH-38 automated mass handler and PPC3-pressure
control cabinet).
controller are stand alone products for which separate Operation and Maintenance
manuals are available with much more complete information than is included in this
manual. Copies of these manuals are provided on the ADCS-601-AF Support CD and are
available at www.dhinstruments.com.
The PG7601 operates on the principle of the piston gauge in which pressure is defined by
balancing it against a known force on a known area (see Figure 11). The known area is
defined by a vertically mounted piston rotating in a cylinder and the known force is applied to
the
the piston by loading it with known mass subjected to acceleration due to gravity.
When
force applied by the pressure and the force applied by the mass accelerated by gravity are in
equilibrium, the piston floats and the pressure under the piston remains constant. The pressur e
can be calculated following the equation in Figure 11. The pressurized fluid under the piston
also
lubricates
the gap between the piston and the cylinder. When floating, the piston must be
rotating to keep it well centered in the cylinder.
The PG7601 is equipped with a 10 kPa/kg piston-cylinder module and 38 kg mass set, giving
it a range of 10 to 380 kPa (3 to 120 inHg). The PG7601 Platform includes a bell jar that can
be evacuated with a vacuum pump so that pressure can be defined against vacuum
(absolute mode) or atmosphere (gauge mode). The AMH-38 mass handler allows the mass
load to be changed automatically. The PPC3 pressure controller adjusts pressure
automatically to float the piston (see Section 2.2.3).
The PG7601 Platform is the instrument base into which the piston-cylinder onto
which the masses are loaded is mounted. The platform also includes the
PG7601’s electronic measurement system.
The PG7601 Platform rear panel provides the connection to the PG Terminal,
remote communication connections and pressure connection ports.

The PG7000 Terminal contains the PG7601 power supplies. It also provides a
local user interface through a 2 x 20 vacuum fluorescent display and 4 x 4
membrane keypad. Local commands to PG7601 are not used in normal
ADCS-601-AF operation. See the PG7000 Operation and Maintenance manual for
details on local operation of PG7000.
The AMH-38 automated mass handler is mounted on the PG7601 Platform (see
Section 2.2.1.1) and serves to automatically change the mass load on the pistoncylinder to set different values of pressure.
The AMH-38 automated mass handler is a stand alone product for which a
separate Operation and Maintenance manual is available with much more
complete information than is included in this manual. A copy of the AMH
manual is provided on the ADCS-601-AF Support CD and is available at
www.dhinstruments.com
The masses of the 38 kg mass set are loaded onto in the piston-cylinder as required
to apply a force corresponding the the set pressure desired. The AMH-38 mass
handler (see Section 2.2.1.4) loads and unloads the masses automatically.

2.2.2 FPG8601 FORCE BALANCED PISTON GAUGE
The ADCS-601-AF Air Data Calibration Standard includes an FPG8601 force balanced
piston gauge to cover the air data pressure range below the range of the PG7601 gas
operated piston gauge. The FPG8601 system includes:
- FPG8601 piston gauge platform with terminal and 10 kPa/kg piston-cylinder (installed
on Reference Bench).
- Capacitance diaphragm gauge with display and isolation valve for measurement of
FPG8601 reference vacuum in absolute mode (mounted on platform).
- PPC3-100K A116Ks/BG15Ks, pressure controller to automate FPG8601 system
pressure control (see Section 2.2.3) (in control cabinet).
- MS-8601-2, 2 kg mass set with
(accessory used separately in metrological maintenance (see Section 7.2.5)).
The FPG8601 force balanced piston gauge and PPC3 pressure controller are stand alone
products for which separate Operation and Maintenance manuals are available with much
more complete information than is included in this manual. A copy of the FPG8601
manual is provided on the ADCS-601-AF Support CD and is available at
www.dhinstruments.com.
The FPG8601 operates on the principle of the piston gauge (see Section 2.2.1); however, the
force resulting from a difference in pressure across the piston is measured by a force
balanced, load cell rather than balanced directly against masses subjected to the
acceleration due to gravity (see Figure 11). The piston-cylinder is suspended from the load
cell. Rather than rotating the piston in the cylinder, the piston-cylinder gap is conical and gas
flow through the gap is used to center the piston. The force across the piston is
to the load cell through a coupling system. There are two independent chambers at either
end
of the piston-cylinder. The lower chamber is held at atmosphere or vacuum while the
pressure to be measured is applied to the upper chamber. The load cell is zeroed with a
pressure difference of zero across the piston (bypass open), taring out the weight of the
piston and coupling and other parasitic forces. Then, with the pressure bypass between the
hanger for validation of FPG8601 load cell linearity.
two chambers closed, the net force resulting from the difference in pressure between the two
chambers is transmitted to the load cell through the coupling. The value of the pressure is
calculated from the effective area of the piston-cylinder and the net force value measured by
the load cell. The 10 kPa/kg piston-cylinder combined with 1.5 kg net measurement span of
the load cell give the FPG8601 a pressure range of 0 to 15 kPa (4.5 inHg).
The FPG8601 Platform is interfaced with the system controller (PC) running FPG Tools
software that calculates pressure and controls the FPG8601 functions.
The PPC3 pressure controller is used to automate pressure control to set the pressure
measured by the FPG8601.

and Maintenance manual is available with much more complete information than is
included in this manual. A copy of the PPC3 manual is provided on the ADCS-601-AF
Support CD and is available at www.dhinstruments.com.
The PPC3 pressure controller uses on/off solenoid valves and internal high precision pressure
transducers to adjust and stabilize pressure precisely in response to remote commands.
The PPC3 front panel provides a local user interface and display for the PPC3 Pressure
Contro ller. Local commands to PPC3s are not used in normal ADCS-601-AF operation. See
the PPC3 Operation and Maintenance manual for details on local operation of PPC3.
The ADCS-601-AF system includes an RPM4 Reference Pressure Monitor that is installed in
the Control Cabinet (see Section 2.1.2). The RPM4 is used as a precise pressure
comparator in the process of compar
validating the FPG8601 (see Section 7.2.3).
The RPM4 is an RPM4 A116Ks.
The RPM4 pressure controller is a stand alone product for which a separate Operation
and Maintenance manual is available with much more complete information than is
included in this manual. A copy of the RPM4 manual is provided on the ADCS-601-AF
Support CD and is available at www.dhinstruments.com.
The RPM4 Reference Pressure Monitor includes a very high precision pressure transducer
(Q-RPT) and the necessary hardware to connect the transducer to the ADCS-601-AF TEST (+)
port when it is needed or isolate and vent it when it is not.
The RPM4 front panel provides a local user interface and display for the RPM4 Reference
Pressure Monitor. Local commands to RPM4 are not used in normal ADCS-601-AF
operation. See the RPM4 Operation and Maintenance manual for details on local operation
of RPM4.
The ADCS-601-AF vacuum pumps are stand alone products for which separate Operation and
Maintenance manuals are available with much more complete information than is included in this
manual. A copy of the manual is provided on the ADCS-601-AF Support CD.
There are two vacuum sources in the ADCS-601-AF system.
- Utility vacuum source: The utility vacuum source provides vacuum to the pressure
controllers so that they can control pressure under atmospheric pressure. The utility vacuum
source is a dry, scroll pump that is normally located under the Reference Bench and has
single connection to the Control Cabinet rear panel.
- Reference vacuum source: The reference vacuum source provides vacuum to the
reference circuit of the PG7601 and FPG8601 pressure standards for operation in absolute
mode. The reference vacuum source consists of a roughing pump and a turbo molecular
pump. The roughing pump is a dry, scroll pump located under the Reference Bench. The
turbo molecular pump is mounted to the bottom surface of the Reference Bench and includes
a Controller mounted in a bracket under the Reference Bench.
See the original manufacturer Operation and Maintenance Manuals for additional information on the turbo
molecular pump and turbo pump controller.

3.2 SITE REQUIREMENTS
The environment required to operate an ADCS-601-AF Air Data Calibration Standard within its estimated
measurement uncertainty limits is generally that of a high level, physical metrology laboratory.
When selecting and preparing a site to set up the ADCS-601-AF system, the following should be considered:
•Ambient conditions: To achieve optimum metrological performance, ambient conditions should be
controlled and maintained within the following limits:
• Temperature: 19 to 23 °C, minimize rate of change of temperature.
• Relative Humidity: 10 to 60 %RH (non-condensing).
• Ambient Pressure: Minimize external influences that will cause barometric instability.
• Air Currents: Do not install the ADCS-601-AF Reference Bench under a source of vertical air currents
such as an overhead air conditioning or heating ducts. These can exaggerate rate of change of ambient
temperature.
•Vibration:Minimize local vibration. Excessive vibration will reduce the stability of the pressures
defined by PG7601 and the FPG8601 (vibration affects the floating piston).
•Overall footprint: The ADCS-601-AF Control Cabinet and Reference Bench must be disposed as
shown in Figure 1. Select a location where adequate space is available, also consider the location of
the system controller (PC) and connection of a
ADCS-601-AF system layout at site of use.
•Access to rear of Control Cabinet and Reference Bench: To perform maintenance functions
troubleshoot the ADCS-601-AF system, it is necessary to have access to the rear of the Control
Cabinet and Reference Bench. Be sure the ADCS-601-AF is installed so that 360 degree access to
areas of the system is available.
•Electrical power supply: Plan the supply of electrical power to the Control Cabinet. See Section
1.1.1 for electrical power requirements. Note that the vacuum pumps draw a
particularly when starting up.
device under test (DUT). See Figure 26 for typical
and
high
amount of power,
•Pressure supplies: Plan the pneumatic pressure supplies to the rear panel of the Control Cabinet.
Two separate supplies are required (see Section 1.1.1). The Test Gas Supply must be very clean
dry. This gas supplies the PG and FPG piston-cylinders. Cleaner gas will reduce maintenance
and
by reducing the necessary piston-cylinder cleaning frequency.
•Bell jar and AMH placement: Plan a location for the PG7601 bell jar and automated mass handler
when they are removed from the platform.
Before setting up the ADCS-601-AF system, see Section 3.2 for information on site requirements.
ADCS-601-AF is a complex system made up of several sub-systems. Setting up and verifying the
complete system is an extensive, step by step, process in which the sequence of operations is
important. Always follow the instructions in Sections 3.3.1 to 3.4.6 in sequential order when setting
up and verifying the system. Allow a minimum of three hours to complete the process.
To set up the ADCS-601-AF system, first unpack it following the instructions in Section 3.1. Then follow
the set up instructions in Sections 3.3.1 to 3.3.13 sequentially. Once the system is set up, power it up,
initialize it and verify it following the instructions in Section 3.4.
Note all fittings, adaptors and parts mentioned in the setup instructions are included with the ADCS-601-AF
lis
unless specifically stated otherwise. See the parts
When assembling, use Teflon® tape or other appropriate thread sealer on all NPT thread fittings.

outside to inside. The largest, long tubes slip down between the main mass
stack and the bell and rest on the ledge at the bottom of the mass bell. The
smaller masses load onto the pyramidal steps of the binary mass carrier.
This phase of mass set installation is complete. The mass lifting shaft assembly
is not yet installed. It will be installed after the AMH autmomated mass handler is
installed over the masses on the platform (see Section 3.3.9.3).
3.3.9.3 INSTALL THE AMH-38 MASS HANDLER
Place the AMH-38 mass handler on top of the Control Cabinet or at another
convenient location near the PG7601 Platform.
Connect the AMH-38 15V power supply to the rear of the AMH-38 and plug it
into the power strip under the Reference Bench.
Connect the 9 pin D-sub cable labeled AMH COM1 to the COM1 port on the
rear of the AMH-38.
Connect the 1/8 in. pneumatic line labeled 8 RED from the Reference Bench
interconnections box to the drive air port on the back of the AMH-38. The
drive air port is the top port of the two quick connectors with a red band.
Press the quick connect stem into the connector firmly until it clicks into
place.
Open the door on the front of a Control Cabinet to access the Control Panel.
Set the AMH DRIVE regulator on the Control Panel as specified in Section 6.13.
Insert the mass lifting shaft into the hole in the center of the AMH mass lifter and
slide it down until the trim mass tray sits on the top of the lifter. This arrangement
trips the AMH’s internal proximity sensor allowing the AMH system to be
operated off of the PG7000 Platform without an actual mass load.
Set the COM1 and COM2 ports of the PPC3-700K pressure controller and
the COM3 port of the PG7601 (see Section 3.4.2).
Power up the PG7601 Platform using the power switch on the rear of the
PG7000 Terminal. If the PG7601 is already powered up, use [SPECIAL], <8AMH>, <2control>, <3loadall> from the PG7000 Terminal front panel.
The AMH-38 trim mass tray should rise approximately 2.5 cm (1 in.) above
the top of the lifter; followed by the sound of the main mass selection
columns rotating. Then the trim mass tray should be lowered back down.
The steps of this procedure are commented on the PG Terminal display as
they execute. See Section 6.5 for additional information on installing and
removing AMH-38 from the PG7601 Platform.
Visually inspect the condition of the AMH-38 mass handler by carefully
tipping it to look inside. The main mass selection columns should have all
their flat surfaces (no ledges) oriented towards the center and all binary
mass selection pins should be retracted. If these conditions are present the
AMH-38 is ready to install on the PG7601 Platform.
Install the AMH-38 mass handler onto the PG7601 Platform (see Section
6.5.1, Figure 50). Verify that the O-ring is installed on the bottom
circumference of the AMH-38 vacuum chamber. Using the handles on the
the AMH-38 vacuum chamber, lift the AMH-38 above the PG7601
of
side
platform and masses. Center it over the mass load and gently lower it down
until the bottom circumference of the AMH-38 vacuum chamber reaches the
PG7601 vacuum plate. Check that the vacuum chamber is well aligned on
the vacuum plate.
Connect the 1/8 in. PFA tube labeled 5 (with blue band on quick connect
stem) from the Reference Bench interconnections box to the vacuum port on
the back of the AMH-38. The vacuum port is the bottom port of the two quick
connectors with a blue band. Press the quick connect stem into the
connector firmly until it clicks into place.
It is imperative that the mass loading shaft be fully threaded into the binary
mass tray. Be sure to use the T handled 3 mm allen wrench to tighten the
shaft to the end of the threads applying sufficient torque to cause the
mass load to rotate. Failure to fully screw in the shaft will cause
misalignment between the mass handler and the mass load that may cause
damage to the AMH-38 mass handler when operated.
Install the AMH-38 mass lifting shaft. Slip the threaded end of the shaft
down through hole in the center of the mass lifter (see Section 6.5.1, Figure
Thread the shaft into the binary mass carrier by holding and rotating the

MUST BE ROTATED COUNTER-CLOCKWISE TO TIGHTEN IT. Use the T
handled, 3 mm allen wrench supplied in the AMH-38 accessories to tighten
the assembly. Tighten until you feel the mass start to rotate.
Level the PG7601 Platform using its two leveling feet and the level mounted
on the top of the AMH-38 mass handling system.
3.3.9.4 INSTALL THE REFERENCE VACUUM CDG ASSEMBLY
The PG7601 and FPG8601 reference vacuum CDGs are delivered with an
isolation valve connected to them. This valve is normally closed and serves
to maintain vacuum on the CDG at all times as exposing the CDG to
atmospheric pressure will cause zero shifts. New CDGs are shipped with
vacuum behind the isolation valve. Do not break the valve fittings or operate
the valve without establishing vacuum first.
Connect the PG7601 reference vacuum CDG assembly (CDG, valve, KF16 x
KF40 adaptor) to the KF40 port on the left (viewed from front) of the AMH-38
vacuum chamber. Use a KF40 centering ring and clamp. Install so that the
CDG body is in the vertical position.

3.4.3.2INITIALIZATION
VERIFY THE PISTON-CYLINDER MODULE, MASS SET AND MASS
LOADING BELL
PG7601 uses stored piston-cylinder and mass set metrological information to
calculate the reference pressures it defines (see the PG7000 Operation and
Maintenance Manual for more detail). For the pressure values to be correct, the
stored metrological information on the piston-cylinder and mass set must be
correct. Before using PG7601 for accurate pressure definition, the validity of the
stored information should be verified. This consists of comparing the pistoncylinder and mass set information stored in PG7601 to the information in the
current piston-cylinder and mass set calibration reports.
With a new ADCS-601-AF system, the piston-cylinder module and mass set
information have already been loaded into the PG7601.
To verify the PG7601 piston-cylinder and mass set information, use the viewing
capabilities accessed by pressing [SPECIAL], <1PC/MS> on the PG7000 Terminal.
Compare the information contained in the PG7601 piston-cylinder and mass set files
to the information on the piston-cylinder and mass set calibration reports.
PG7601 uses many variables in calculating defined pressures. The sources of
the variables are determined by the current SETUP file. SETUP files are viewed,
created, edited and selected using the SETUP function accessed by pressing
[SETUP] on the PG7000 Terminal. ADCS-601-AF systems use SETUP file #2.
VERIFY/SELECT AUTOGEN ON

steps may be used to verify operation:
Check gauge mode operation of the PG7601 and FPG8601 systems:
Plug the ADCS-601-AF TEST(+) port with the plug quick connector stem provided.
- Set operation to gauge mode in FPG Tools (see Section 4.2.3).
Set a target pressure of 380 kPa (112 inHg) (see Section 4.2.4). The PG7601 should
-
automatically load mass, use the PG7601 PPC3 pressure controller to increase
pressure and float the PG7601 piston, rotate its piston and
indicate Ready. Onc
Ready is indicated and about 30 seconds have been allowed for pressure stabilization,
the drop rate of the PG7601 should not exceed –0.2 mm/min. A faster drop rate value
than –0.2 mm/min indicates a possible leak.
- Set a target pressure of 20 kPa (6 inHg). The PG7601 should change the mass load,
use the PG7601 PPC3 pressure controller to decrease pressure and float its piston,
rotate its piston and indicate Ready.
e
- Set a target pressure of 10 kPa (3 inHg). The ADCS-601-AF will transition from the
PG7601 to the FPG8601 standard. The FPG8601 pressure controller should descend
pressure and set a stable pressure near the target pressure value and indicate Ready.
- Set a target pressure of 1 kPa (0.2 inHg). The FPG8601 pressure controller should
descend pressure and set a stable pressure near the target pressure and indicate Ready.
Check absolute mode operation.
- Set ADCS-601-AF operation to absolute mode (see Section 4.2.3). Wait for the mode
transition to complete. The reference
Pa (11 mTorr) within 20 to 30 minutes.
- Set a target pressure of 80 kPa (24 inHg) (see Section 4.2.4). The PG7601 should
automatically load mass, use the PG7601 PPC3 pressure controller to decrease
pressure and float its piston, rotate its piston and indicate Ready. Onc
indicated and about 30 seconds have been allowed for pressure stabilization, the drop
rate of the PG7601 should not be positive. A positive value indicates a possible leak.
- Set a target pressure of 30 kPa (9 inHg). The PG7601 should automatically load mass,
use the PG7601 PPC3 pressure controller to decrease pressure and float its piston,
rotate its piston and indicate Ready.
- Set a target pressure of 10 kPa (3 inHg). The ADCS-601-AF will transition from the
PG7601 to the FPG8601 standard. The FPG8601 pressure controller should descend
pressure and set a stable pressure near the target pressure value and indicate Ready.
- Set a target pressure of 1 kPa (0.2 inHg). The FPG8601 pressure controller should
descend pressure and set a stable pressure near the target pressure and indicate
Ready. Note: It may take up to 3.5 to 4 minutes to obtain a ready condition for
descending increments at very low absolute pressure.
Run an FPG validation in absolute mode (see Section 7.2.3).
3.5 ENTER VALUE OF LOCAL GRAVITY
To correctly calculate the pressure defined by its PG7601 and FPG8601 pressure standards,
local value of acceleration due to gravity must be known and entered into ADCS Tools.
To enter the local value of acceleration due to gravity into ADCS Tools, press
[Maintenance] on the main menu and select [Calibration]. Edit the value of local gravity to
enter gravity at the site of use of the ADCS-601-AF System (see Figure 28).
See the PG7000 and FPG8601 Operation and Maintenance Manuals for additional
information on how acceleration due to gravity is used in the calculation of defined pressure.
Figure 28. Local gravity and pressure medium fields in ADCS Tools
The ADCS-601-AF system, and especially the FPG8601 pressure standard, are dependent
upon the species of the test gas used.
The test gas used must be correctly specified in ADCS Tools.
To enter the test gas species into ADCS Tools, press [Maintenance] on the main menu and
select [Calibration]. Select the test gas that is supplied to the ADCS-601-AF Control
Cabinet TEST GAS SUPPLY port (see Figure 28). The gas choices are limited to Nitrogen
and Air.
3.7 ADDITIONAL PRECAUTIONS TO TAKE BEFORE MAKING
PRESSURE MEASUREMENTS
Before using ADCS-601-AF, consider the following:
• Enter the correct value of local gravity at the site of use in ADCS Tools (see Section 3.4.5).
• Consider head corrections (see Section 4.2.6).
• Level the PG7601 and FPG8601 Platforms properly using their bubble levels.
•
Verify that the PG7601 piston-cylinder module is correctly cleaned and operating properly
(see Section 6.6).
•Verify that there are NO leaks in the system connected to the test port.
Assure that adequate metrological maintenance has been performed (see Section 7).
•
3.8 SHUT DOWN AND RESTART
3.8.1 RESTART
To restart an assembled ADCS-601-AF, follow the steps below. If the ADCS-601-AF has
been shut down for an extended period, consider performing the maintenance functions (see
Section 6).
If they have been disconnected, connect and apply required pressure supplies to the
Control Cabinet rear panel (see Section 1.1.1).
Connect AC1, AC2, AC3 power cords from Control Cabinet to power supplies. Turn ON
main power switches (INSTRUMENTS, REFERENCE PUMPS and UTILITY PUMP) on
front of Control Cabinet. The utility vacuum pump should start up, if not check its local
power switch.
Run the FPG Tools program on the system controller by selecting the FPG Tools icon
on the desktop. Once the program has opened, select [Run], [Run Monitor] to initialize
the FPG8601. Wait for initialization to complete.
Run the ADCS Tools program on the system controller by selecting the ADCS Tools
icon on the desktop. Once the program has opened, press the [ON] button. Follow the
prompts to complete the ADCS-601-AF initialization process. Select the desired
measurement mode when the prompt appears.
ADCS-601-AF should ready for regular operation (see Section 4).
Pressure must always be supplied to the TEST GAS SUPPLY port on the rear of the
Control Cabinet unless the FPG8601 has been shut down following the long term shut
down instructions in Section 3.8.2.2. Failure to supply pressure to the FPG8601
lubrication gas circuit will cause damage to the instrument.
There are two different standard ADCS-601-AF shut down conditions.
1) Short term shut down: Short term shut down is intended to limit power consumption
and preserve vacuum pump life when the system is not used for limited periods of
time such as overnight or over a weekend (see Section 3.8.2.1). Short term shut
down may
down if support facilities allow it.
2) Long term shut down: Long term shut down is intended to completely shut down
the ADCS-601-AF system when it will not be used for extended periods of time or
before it will be disassembled. Long term shut down should be avoided to the extent
possible as restarting from long term shut down is more likely to require maintenance
procedures before normal operation is restored.
also be used for extended periods and is preferable to long term shut
3.8.2.1 SHORT TERM SHUT DOWN
To reduce consumption of power and preserve vacuum pump life, the following
conditions may be implemented when the ADCS-601-AF is not in use, for
example over the weekend. In this state, ADCS-601-AF is in gauge
measurement mode with the utility vacuum pump turned off.
Put system into gauge measurement mode by pressing the [Measurement
Mode] button on the ADCS Run Screen Toolbar (see Section 4.3.5.3). If
necessary, wait for the mode transition to complete.
Turn OFF the UTILITY PUMP power switch on the front of the Control Cabinet.
DO NOT disconnect pressure supplies. Pressure supplies must be maintained.
Utility vacuum must be supplied to the ADCS-601-AF for it to operate
normally, even in gauge mode. Be sure to reestablish utility vacuum after a
short term shut down. Failure to do so will prevent ADCS-601-AF from
functioning properly.
3.8.2.2 LONG TERM SHUT DOWN
If the ADCS-601-AF will not be used for an extended period, or to shut it down
completely for disassembly, proceed as follows.
Complete the short term shut down (see Section 3.8.2.1).
Use the ADCS Tools [FPG] button to display the FPG run screen. In the
ADCS Tools FPG Run Screen, press the [Shutdown] (OFF) button.
Wait for the FPG8601 to indicate Ready and the measured pressure to indicate
< -- SHUTDOWN -- > indicating the FPG is shut down.
Disconnect pressure supplies and turn OFF power using main switches on
The ADCS-601-AF system is completely configured from a hardware and software standpoint
when it is delivered. All necessary operating values are entered into individual components and
all interfaces are set for internal consistency and to communicate with ADCS Tools software.
The system hardware configuration can be viewed and edited using panels [Setup], [Configuration] form. Changes to the configuration should only be made when necessary
by personnel with advanced knowledge of the system. Uninformed changes to the
configuration are likely to cause ADCS-601-AF to no longer operate properly.
4.1.2 READY/NOT READY INDICATIONS
4.1.2.1 OVERVIEW
Typcial ADCS-601-AF operation consists of using the system to set values of
pressure with very low measurement uncertainty. A variety of operations by the
ADCS-601-AF system may be required to achieve the requested pressure and
the time required to complete these may vary. In order to make it clear to the
operator when a pressure setting request has been completed and conditions
are appropriate for the ADCS-601-AF pressure definition to be within the
estimated measurement uncertainty budget, ADCS-601-AF provides a “go/no go”
Ready/Not Ready indication.
The Ready/Not Ready indication is provided by the ADCS Tools software that
manages the overall system (see Section 4.3). The indication is by a circle to the
of
left
Ready and Green when the pressure is Ready.
The conditions that must be met to reach a Ready condition vary depending upon
whether the active pressure standard is the PG7601 piston gauge or the FPG8601
force balanced piston gauge. See Sections 4.1.2.2 and 4.1.2.3 for additional
information on the Ready/Not Ready criteria for the two pressure standards.
4.1.2.2 READY/NOT READY WHEN USING THE PG7601 PISTON
the current pressure reading which is RED when the pressure is Not
GAUGE
ADCS-601-AF uses the Ready/Not Ready directly from the PG7601 to
determine the Ready/Not Ready condition. See the PG7000 Operation and
Maintenance manual for a more detailed description of PG7000 Ready/Not Ready operation.
When the PG7601 is the active pressure standard ADCS-601-AF pressure
Ready/Not Ready depends directly upon the PG7601 Ready/Not Ready condition.
The PG7601 Ready/Not Ready condition is dependent upon three criteria. For
the PG7601 pressure to be considered Ready, all three crteria must be met.
1. Piston position: For a Ready condition to exist, the PG7601’s piston must be
floating within the position limits defined in the PG7601’s active SETUP file
AND the PPC3 pressure controller is not controlling. The default PG7601
SETUP file is #2. The default piston position Ready limits are - 2.5 mm and
+ 2.5 mm of midstroke. The full stroke of the piston from top stop to bottom
stop is + 4.5 to - 4.5 mm.
2. Piston rotation rate: For a Ready condition to exist, the PG7601’s piston
must be rotating at a rate within the rotation rate limits defined in the pistoncylinder’s characteristics file. The default is 10 to 40 rpm. When the mass
load on the PG7601 is < 3 kg (corresponds to pressure of < 30 kPa (9 inHg))
the maximum rate limit is removed.
3. Reference vacuum level in absolute mode: In absolute measurement mode,
for a Ready condition to exist, the reference vacuum as measured by the
reference vacuum capacitance diaphragm gauge must be lower than the
vacuum limit specified in the PG7601’s active SETUP file. The SETUP file is
#2. The default minimum reference vacuum value is < 5 Pa (38 mTorr).

BALANCED PISTON GAUGE
When the FPG8601 is the active pressure standard, ADCS-601-AF pressure
Ready/Not Ready depends upon the value and stability of the pressure
measured by the FPG8601 and the internal limits within FPG Tools. FPG8601
internal limits will force a Not Ready condition in the FPG8601 when ambient
conditions have significantly changed since the last FPG8601 zero. A feature in
the [Maintenance],[FPG Cal Options] menu is provided to decouple the
FPG8601 internal limits and the Ready/Not Ready status of the ADCS-601-AF
when the FPG8601 is the active reference (see Section 7.2).
When Regulation (see Section 4.1.4) is OFF, the
Ready condition when using the FPG8601 is dependent on:
1.
FPG8601 pressure stability: For a Ready condition to exist, the FPG8601’s
pressure rate of change must be less than the FPG8601 stability criterion.
The default FPG8601 stability criterion is ± 0.5 Pa/s (0.00015 inHg/s).
When Regulation (see Section 4.1.4) is ON, the ADCS-601-AF Ready/Not Ready condition when using the FPG8601 depends upon:
1. FPG8601 pressure hold limit: For a Ready condition to exist, the pressure
measured
limit. The default hold limit is ± 1.0 Pa (0.0003 inHg).
2. FPG8601 pressure stability: The FPG8601 pressure stability criterion is not
used to determine Ready when the ADCS-601-AF is actively controlling a
pressure. When pressure control is aborted, a Ready condition will occur
when the FPG8601’s pressure rate of change is less than the FPG8601
stability criterion.

4.1.3 TRANSITION BETWEEN STANDARDS, ACTIVE AND
INACTIVE STANDARD
The ADCS-601-AF system is made up of two automated pressure standards with overlapping
ranges to cover the full pressure range. An automated PG7601 piston gauge covers the
range of 15 to 380 kPa (4.5 to 120 inHg) (see Section 2.2.1). The PG7601 range is extended
by
down to 1 kPa (0.3 inHg)
pressure control (see Section 2.2.2).
an FPG8601 force balanced piston gauge with automated
In normal operation, the ADCS Tools software that manages the ADCS-601-AF system,
determines which pressure standard system to use based on the pressure value to be set.
ADCS Tools also handles the transition from one standard to the other when the requested
pressure point requires changing the active pressure standard.
There is always an active pressure standard (see Table 11). Active is defined as connected
to the ADCS-601-AF TEST(+)
port. Changing the active pressure standard requires
changing the states of the PG and FPG ISOLATION valves (valves 1 and 2) (see Figure 29)
to
without causing excessive perturbation to the pressure applied
the TEST(+) port and the
device under test. This is accomplished by using the two PPC3 pressure controllers to set
the same pressure on either side of the isolation valve. Once this transition pressure has
been set and stabilized, the valves are operated. The default transition pressure is 15 kPa in
absolute mode and 14 kPa in gauge mode. The value can be changed in ADCS Tools,
[Setup], [Configuration], [Limits] but this is not recommended.
The transition between standards is initiated automatically when a pressure request is made
that requires the standard that is not currently active. A transition can also be initiated using
the [Standard Transition] button on the ADCS Run Screen Toolbar (see Section 4.3.5.3).

4.1.4 DIFFERENCE BETWEEN REQUESTED AND ACTUAL SET
PRESSURE
ADCS-601-AF is not designed to set exactly the pressure that has been requested. Rather, it
sets a value of pressure very close to the requested pressure and returns the exact pressure
value it has set.
The majority of the ADCS-601-AF pressure range (15 kPa (4.5 inHg) and up) is covered by
an automated PG7601 piston gauge (see Section 2.2.1). The automated mass handling
system of the PG7601 can load mass in steps
cylinder, 0.1 kg corresponds to increments of 1 kPa (0.3 inHg). When a pressure is
requested of the PG7601, it calculates the mass to load to reach the pressure. It then loads
the mass as closely as possible using its 0.1 kg resolution, calculates the actual pressure
achieved and displays that value. Therefore, when using the PG7601, the actual pressure
set may be up to 0.5 kPa (0.15 inHg) different from the pressure requested.
The FPG8601 pressure standard used to handle pressure requests under 15 kPa (4.5 inHg) (see
Section 2.2.2) is normally used in a similar manner.
commanded to set and stabilize the requested pressure. Due to the possible difference between
the PPC3’s pressure transducer and the FPG8601, the final pressure set by the PPC3 will not be
exactly the requested pressure as read by the FPG8601. Since the FPG8601 is the pressure
standard and has much lower measurement uncertainty than the PPC3’s transducer, the
FPG8601’s reading is displayed as the ADCS-601-AF pressure value.
When using the FPG8601 (pressure points under 15 kPa (4.5 inHg), it is possible to set exactly
the requested pressure by using Regulation mode. In Regulation mode, the PPC3 pressure
target is iteratively adjusted by the difference between the PPC3 pressure transducer reading
and the FPG8601 reading to cause the FPG8601 to read the requested value of pressure within
the FPG8601 pressure hold limit. See Section 4.1.2.3 for information on pressure Ready/Not Ready criteria when using FPG8601 with Regulation mode

Tools Run Screen Control Panel when the FPG8601
is the active pressure standard (see Section 4.3.5.1).
4.1.5 ASOLUTE AND GAUGE MEASUREMENT MODES
The
FPG8601’s PPC3 pressure controller is
ON and OFF. Regulation mode
ADCS-601-AF can operate in two measurement modes.
In absolute mode pressure is defined relative to a vacuum. Vacuum is provided by the
system reference vacuum pumps and is applied to the reference circuit of the pressure
standards (see Figu re 29) . The residual vacuum level is ready by thePG7601 and FPG8601
reference vacuum CDGs.
In gauge mode pressure is defined relative to atmosphere. The reference vacuum pumps
are turned O
FF or isolated and the reference circuit of the pressure standards is opened to
atmosphere. The DUT may be connected to the reference circuit on the TEST(-) port to
assure that the DUT and pressure standards are at a common reference pressure.
See Section 4.2.3 for additional information on changing measurement modes.
There is a well defined order of operation for transitioning the ADCS-601-AF system
between measurement modes. The order is controlled by the ADCS Tools software. Mode
transitions should only be performed under ADCS Tools control. Vacuum pumps must
always be left ON in absolute mode. Before turning OFF vacuum pumps or disconnecting
vacuum supplies, transition to gauge mode. Once a measurement mode change is
initiated, it should be allowed to complete uninterrupted.
4.2 FREQUENTLY USED FUNCTIONS
Regular ADCS-601-AF operations relating to connecting and disconnecting devices under test and
setting pressures are performed from the ADCS ToolsADCS Run Screen (see Section 4.3.5).
How to perform common ADCS-601-AF functions is summarized in Sections 4.2.1 to 4.2.8).
The ADCS-TEST(+) port should never be pneumatically accessed (make or break connection)
unless the ADCS is “vented” following the instructions below. Damage to the system and/or
the DUT may result from opening the TEST(+) port in other than “vented” condition.
The device or devices under test (DUT) are connected to the TEST port(s) at the front of the
ADCS-601-AF Reference Bench.
Absolute measurement mode devices are connected to the TEST(+) port only. For gauge or
“differential” mode devices the high side is connected to the TEST(+) and the low side is
connected to the TEST(-) port. The TEST(-) port is at atmospheric pressure when the
ADCS-601-AF is in gauge mode.
The TEST port connections are self sealing quick connectors (with no quick connector stem
installed, they are closed). To connect, use one of the quick connector stems supplied with
the ADCS-601-AF accessories. For proper ADCS-601-AF operation it is important that the
system connected to the TEST port(s) be leak free and the volume connected to the TEST (+) port not exceed 1 liter (61 in.

To access the test port, it must be vented to atmosphere.
In gauge measurement mode: the TEST(-) port is always vented. To vent the TEST(+)
port, press the [VENT] button on the ADCS Run Screen Toolbar (see Section 4.3.5.3) and
wait for the vent process to complete (indicated <Pressure> is <0.000> and Ready). The
port can then be accessed safely without damage to the DUT or the system.

4.2.2CHANGING PRESSURE UNIT OF MEASURE
ADCS-601-AF supports a variety of pressure units of measure. To change the pressure unit
for the ADCS pressure, press the [Unit of Measure] button on the ADCS Run Screen Toolbar (see Section 4.3.5.3) and select the desired unit. When the ADCS pressure unit of
measure is changed, the unit of measure of the ADCS-601-AF components (RPM pressure

Pressing the [MEASUREMENT MODE] button itself, rather than the down arrow next to it, is
used to reset the current measurement mode.
4.2.4 SETTING PRESSURES
Before setting a pressure, be sure that the TEST(+) port is not open to atmosphere or
connected to a system with a very large leak. Execution of certain pressure requests could
damage the ADCS-601-AF system if the TEST(+) port is open. If nothing is connected to the
TEST(+) port, it must be plugged with the plug quick connect stem provided.
To set a pressure with ADCS-601-AF, first verify that ADCS-601-AF is in the desired
measurement mode (gauge or absolute) (see Section 4.2.3) and that the TEST(+)
open to atmosphere. If nothing is connected to the TEST(+) port, it should be plugged with
the plug quick connector stem provided.
port is not
Enter the desired target pressure in the ADCS Control Panel<Target Pressure> field and
press [ENTER] on the system controller (PC). Observe the ADCS Status Bar and System Display for information on progress in setting the requested pressure (see Section4.3.1). When
the requested pressure has been set and stabilized, a Ready indication is given (see Section
4.1.1) and the actual value of the set pressure is displayed in
the <Pressure> field. In most
cases, the final set pressure is not exactly equal to the target pressure (see Section 4.1.4).
4.2.4.1SETTING ZERO PRESSURE
Setting zero in absolute measurement mode
In absolute measurement mode, entering a target pressure of zero transitions the
active pressure standard to the FPG8601 if it is not already active, controls down
using the FPG’s PPC3 pressure controller to the pressure defined in [Setup], [Configuration], [Limits] and then opens the FPG bypass valve (see Figure 29).
This causes the pressure on the FPG8601 and at the ADCS-601-AF TEST(+
to be pulled down as low as possible directly by the reference vacuum pump
system. The pressure achieved is indicated in the ADCS Control Panel <Pressure> field. Ready is indicated when the FPG8601 stability criterion is
reached.
) port,
Setting zero in gauge measurement mode
The result of entering zero as the target pressure in gauge measurement mode
depends upon a [Maintenance], [FPG Cal Options] selection (see Section 4.3.2).
If the <Vent using
the FPG in gauge measurement mode> option IS NOT
selected, the active pressure standard is transitioned to PG7601 if it is not already
active and the PG7601’s PPC3 controller vents to atmosphere setting zero gauge
pressure. The ADCS Control Panel <Pressure> field is fixed to <0.000>. This is the
default setting.
If the <Vent using the FPG in gauge measurement mode> option IS selected, the
active pressure standard is transitioned to FPG8601 if it is not already active and the
FPG8601’s PPC3 controller vents to atmosphere setting zero gauge pressure.
The ADCS Control Panel <Pressure> field indicates the reading of the FPG8601.
4.2.4.2 SETTING IDLE STATUS
This section describes the ADCS-601-AF idle condition. The system can be
left in this condition indefinitely but the system must remain powered ON
and supplied with pressure and vacuum. See Section 3.7 for information on
ADCS-601-AF system short and long term shut down procedures.
In the normal idle (resting) condition of the ADCS-601-AF system, the pressure
applied to the TEST(+) port is vented. This can be accomplished by pressing the
ADCS Run Screen Toolbar [VENT] button (see Section 4.3.5.3) or setting a
target pressure of zero in gauge measurement mode (see Section 4.2.4.1).
When vented in absolute mode,
indicates < --- VENT --- > and the pressure is Ready. When vented in gauge
mode, the <Pressure> field indicates <0.000> and the pressure is Ready.
4.2.5 PRESSURE EXERCISING THE DEVICE UNDER TEST
Many devices require pressure exercising prior to validation or calibration. Generally, their
exercising can be performed quickly and without precise knowledge of the endpoint pressures.
ADCS-601-AF supports a function to allow simple, rapid exercising of the DUT. The exercise
function uses the PG7601’s pressure controller alone rather than the pressure standards.
To run an exercise routine, press the [Exercise Pressure] button on the ADCS Run Screen Toolbar (see Section 4.3.5.3). Then fill in the form to define the desired exercise routine
(see Figure 30).
The <Dwell> is a wait time at the maximum pressure for each cycle. The <Control
Timeout> is the amount of time ADCS Tools will attempt to set a required pressure before
giving up and continuing if it is unsuccessful.
After defining the exercise routine, press [OK] to proceed with the exercise routine. To
interrupt the routine, use the [Abort] button on the Main Toolbar (see Section 4.3.3) or the
[Abort Control] button on the ADCS Run Screen Toolbar (see Section 4.3.5.3).
Figure 30. ADCS Tools pressure exercise definition form
4.2.6SETTING A HEAD CORRECTION
ADCS-601-AF can automatically correct for the difference in height between the ADCS-601AF reference level and the reference level of a device under test (DUT). The head
correction, adds or subtracts the pressure corresponding to a difference in height by
calculating the pressure head using the density of the test gas at the measured pressure.
The reference level of the ADCS-601-AF system is the reference level of the PG7601 piston
gauge which is marked on the front of the AMH automated mass handler vacuum chamber.
The difference in height between the ADCS-601-AF reference level and the DUT reference
level, is entered in the ADCS Control Panel <Head Correction> field. The value is positive
if the DUT reference level is higher than the ADCS reference level and negative if the DUT is
lower than the ADCS. The value is always entered in centimeters (cm).
4.2.7 STOPPING PRESSURE CONTROL, ABORTING FUNCTION
EXECUTION
To abort current pressure control, press the [Abort Control] button on the ADCS Run Screen
Toolbar (see Section 4.3.5.3). This causes the PPC3 pressure controller to stop actively
controlling and shut off from the system. To resume, a new target pressure must be entered.
To abort execution of a function (e.g. pressure standard change, measurement mode change,
FPG8601 validation, press the [Abort] on the ADCS Main Toolbar. This causes execution of the
function to stop. Nothing further occurs until a new instruction is given. The ADCS Main Toolbar
[Abort]
button is only available when a function that can be aborted is running.
Aborting execution of a measurement mode change may leave the system in an <Unknown
Measurement Mode> state. If this occurs, set a measurement mode (see Section 4.2.3)
before attempting any other operation.
The ADCS Main Toolbar has a [Pause] button. This button is to pause system operation.
To resume operation after pressing [Pause], press [Pause] again.
The ADCS Tools program that runs the ADCS-601-AF system includes provisions to protect
against undesired editing and changes to program parameters. The protection system is
based on user rights.
ADCS Tools always has an active user. User access can be password protected. User
rights can be managed to prevent a user from being able to make changes in specific areas
of ADCS Tools.
See Table 12 for a description of the User Access areas that can be limited by management
of user rights.
The typical set up of ADCS Tools to
manager user rights is for the “Admin” user to be
password controlled and only used by the system manager. The system manager can then
set up and delete specific users with user passwords as desired.

4.2.9 PRESSURE LEAK TEST
It is good practice to run a leak test on the ADCS-601-AF after performing a setup or
maintenance operation that requires pressure fittings to be disconnected. The leak test can
quickly determine if the ADCS-601-AF is performing properly. A report detailing the status of the
individual portions of the leak test is provided upon test completion. The information in this report
is used to isolate leaks in the ADCS-601-AF system (see Figure 31).
To run a pressure leak test, first put in the
ADCS-601-AF
in absolute measurement mode
(see Section 4.2.3). After at least one hour in absolute mode, press the [Leak Test] button
on the ADCS Run Screen Toolbar (see Section 4.3.5.3). User confirmation is required to
ensure that there are no DUTs connected to t
he ADCS-601-AF that cannot support the leak
test pressure. During the leak test, pressures of 375 kPa (110.7 inHg) and 15 kPa (4.4 inHg)
are set.
Do not attempt to run a leak test until the ADCS-601-AF has been in absolute
measurement mode for at least 1 hour. The residual vacuum reference can change
significantly during the first hour of absolute measurement mode operation after
transitioning from gauge measurement mode. This change in pressure can cause the leak
test to fail.
There are three parts to the leak test: PG7601 drop rate test, residual vacuum test and FPG
lubrication flow test. If any part of the leak test fails, the overall leak test fails.
The PG7601 drop rate portion of the leak test sets a high and low pressure with the PG7601.
After stability is achieved the change in piston position over a 30s interval is used to
determine the drop rate of the piston-cylinder. The recorded drop rates are compared to
factory defined drop rate limits to determine a PASS/FAIL status. A high piston drop rate
indicates a leak in the pressure circuit that interconnects the TEST(+) port, the PG7601 and
the PG7601 pressure controller.
The residual vacuum portion of the leak test records the FPG8601 and PG7601 vacuum
reference sensor outputs when the FPG8601 bypass valve is closed. The residual vacuum
test is executed during the high pressure portion of the PG7601 drop rate test. The recorded
residual vacuum pressures and the difference between them must fall below factory
determined limits to pass the residual vacuum portion of the leak test. The residual vacuum
test fails when a leak into the vacuum reference circuit is present.
The FPG8601 lubrication flow portion of the leak test is executed while the PG7601 drop rate
test is setting the high pressure. In this test, the FPG8601 bypass valve is closed to monitor
the rate of increase in the FPG8601 pressure due to the lubrication flow. Without pressure
control, the FPG8601 pressure increases as a result of the FPG8601 lubrication flow when
the FPG8601 bypass valve is closed. The change in the indicated FPG8601 pressure is
recorded over a 30s interval to determine the pressure rate of change caused by the
lubrication flow. The recorded value must fall below factory defined limits to pass the
FPG8601 lubrication flow portion of the test. A failure indicates a leak in the pressure circuit
which interconnects the upper FPG8601 mounting post, the FPG8601 pressure controller
(PPC3), and the FPG8601 isolation valve (valve 2).

4.3 LOCAL OPERATION, ADCS TOOLS
4.3.1 OVERVIEW
ADCS Tools, running on a personal computer, is the software program that controls the
overall ADCS-601-AF system (see Figure 32). ADCS Tools communicates with other
software programs and system instruments, providing instructions and reading their
responses to execute ADCS-601-AF system functions.
ADCS Tools also provides the local
user interface through the system controller’s display,
keyboard and pointing device. Direct operator interaction with ADCS-601-AF system
subprograms and individual system instruments is not required in normal operation.
Operator interaction with the ADCS Tools program is through four main program features
that follow conventional Microsoft® Windows
TM
protocol for file management, menu and
message formatting, graphics and editing. The ADCS Tools features are:
1. Main Menu (see Section 4.3.2): The Main Menu is a bar across the top of the ADCS
Tools program window. Each main menu selection leads to a drop down menu.
2. ADCS Main Toolbar(see Section 4.3.3): The Main Toolbar is across the top of the
screen just under the Main Menu.
The toolbar is made up of buttons that are shortcuts
to ADCS menu items and functions.
3. ADCS Status Bar (see Section 4.3.4): The Status Bar is across the bottom of the
ADCS Tools
program window. It continually displays current ADCS system activity at
multiple levels. The ADCS Status Bar is the best source of information on what the
ADCS-601-AF system is doing at any particular moment.
4. ADCS Run Screen (see Section 4.3.5): The Run Screen is the main operator interface
for actually running the
instrument
and includes real time ADCS-601-AF displays and controls. The ADCS Run
ADCS-601-AF system. It is equivalent to the front panel of an
Screen includes the ADCS Control Panel, ADCS System Display and ADCS Run
Screen Toolbar.
5. Other Run Screens (see Section 4.3.6):
system components with which ADCS Tools
screens are also available to view data while tests are running.
The ADCS Main Menu is a bar across the top of the ADCS Tools program window. Each
main menu selection leads to a drop down menu.

devices according to the active averaging method. This is identical to
averaging data during a test. Both automatic and manual averages can be
used to average the data. The drop down arrow displays a menu that lists
the automatic and manual averaging options. The option with an “*”
preceding it is the active averaging mode.
To change the automatic averaging time select it in the menu and enter the
desired averaging time in the input box that follows. Data can be

When running a Test Definition autoamted test, causes the current test point
to be interrupted and the test point sequence to step forward to the next step
in the point sequence. This feature only moves forward up to the take data
step of the highest point executed. The limitation is to ensure that data is
logged at each point and points are not skipped entirely. Most often this

ADCS Tools uses the engine of COMPASS for Pressure® calibration software to manage
automated testing using ADCS-601-AF. Frequent reference is made to the COMPASS
for Pressure User’s manual for detail on setting up and running automated tests that is
beyond the scope of this manual. The COMPASS for Pressure manual is an on-line
manual available by pressing the [?] button, when available, in COMPASS features. It can
also be accessed on the ADCS-601-AF system controller in the COMPASS for Pressure
program group reached using the Windows START button , Programs.
ADCS-601-AF has the capability to run automated tests. Automated tests are tests in which
a device under test (DUT) is defined and test data is logged to a data file. If the DUT is able
to be interfaced with ADCS-601-AF by an RS232, IEEE-488 or USB interface, readings can
be acquired from it automatically during the test.
Two test run modes are available. [Run Manual Test] runs a point by point test controlled
by the operator. [Run Test Definition] runs a multi-point test script on a device under test
(DUT). Running a test definition with a DUT whose output can be interfaced with
ADCS-601-AF allows a complete test sequence to be run unattended by an operator.
See Section 4.4.1 for information on setting up to run automated tests.
ADCS Tools is preconfigured to support automated validation (calibration) and
standardization of the King Nutronics 3682 Air Data Calibrator (see Section 4.4.6).
See Section 4.4.2 for information on running automated tests.
4.4.1 SETTING UP TO RUN AUTOMATED TESTS
To run an automated test, a DUT Definition must be setup to identify the device under test
(see Section 4.4.1.1). To run a multipoint test following a scripted test scenario,
Definition must also be set up (see Section 4.4.1.2). If support devices that are not part of
the ADCS-601-AF such as a multimeter
or a temperature chamber are needed to run a test,
Support Device Definitions must be set up to define them (see Section 4.4.1.3).
4.4.1.1 SETTING UP DEVICE UNDER TEST (DUT)
ADCS Tools uses the engine of COMPASS for Pressure® calibration software
to manage automated testing using ADCS-601-AF. The DUT Editor is a
COMPASS for Pressure Device Editor. See the COMPASS for Pressure
User’s Manual for complete information on Device Editors and DUT
Definitions. The COMPASS for Pressure manual is an on-line manual
available by pressing the [?] button, when available, in COMPASS features. It
can also be accessed on the ADCS-601-AF system controller in the
COMPASS for Pressure program group reached using the Windows START
button , Programs.
a Test
ADCS Tools automated testing is organized around the support, testing and
maintenance of Devices Under Test (DUTs). DUT Definitions not only specify
the relationship between raw device outputs and pressure; they determine how
the output data will be acquired and maintain calibration and tracking information
for the device. A DUT can be setup to provide DUT pressure only or to include
measurement of other variables.
The DUT Editor provides features to create, edit, view and remove DUT
Definitions from the ADCS Tools database. Access the DUT Editor by pressing
[Setup], [DUT] from the ADCS Tools main menu or pressing the [DUT Editor]
button on the main toolbar. When selected, the last accessed DUT Definition
displays. To edit an existing DUT, use the Editor Toolbar features to select the
desired DUT. Then simply edit the desired fields. Press the Editor Toolbar,
[Save] button to save the changes.
Sample DUTs are already included in the DUT Definition database as examples.
Use the following steps to create a DUT Definition.
Select [Setup], [DUT]
Press the Editor Toolbar, [New] button. Enter a <Record Label> that allows users to quickly identify the defined DUT. Begin completing the DUT Definition starting with the [Header] tab. Select a
<DUT Type> and a <Record Type>.
DUTs can be defined as <Individual>, <Profile> and <Profile w/Range>. These
selections allow an explicit DUT to be created including specific range and
serial number information; or, a profile DUT that is identified during the test
initialization process. Profile DUTs allow one DUT Definition to represent any
number of like <Model> devices from the same <Manufacturer>.
Select the <Manufacturer> and <Model> on the [Header] tab. If the
desired selections are in the drop down list, press the [Find Previous
Setup] button to search for previous setups or examples of the DUT.If the
<Manufacturer> and <Model> are not in the list, enter them.
Enter relevant information on the [Calibration] tab.
Select the appropriate <Data Acquisition Type> and corresponding settings
using the [Communications] tab.
If applicable, select the [Output] tab. Simple DUTs allow direct entry of all
relevant final output information. To create a final output for advanced
DUTs, press the [Add] button and edit the information on the Output
Relationship Editor. If the final output requires remote commands to read the
<Raw Output>, press the [Edit Commands] button to launch the Remote
Command Editor. Simple DUT remote commands are accessed on the
[Communications] tab. Specify the commands required to interface with
the device. Press the [Add] button to add as many final outputs as are
supported by the DUT.
The [Set] tab is used when the DUT will be used as a controller. However,
the DUT cannot be used as a controller in ADCS Tools.
Press the Editor Toolbar, [Save] button to save all changes. Any errors in
the setup must be remedied before the DUT Definition can be saved.
ADCS Tools uses the engine of COMPASS for Pressure® calibration software
to manage automated testing using ADCS-601-AF. The Test Editor is a
COMPASS for Pressure feature. See the COMPASS for Pressure User’s
Manual for complete information on Test Editor. The COMPASS for
Pressure manual is an on-line manual available by pressing the [?] button,
when available, in COMPASS features. It can also be accessed on the
ADCS-601-AF system controller in the COMPASS for Pressure program
group reached using the Windows START button , Programs.
Test Definitions are used to define a specific test procedure including the
sequence of test points and a large number of operational details. DUT(s) to be
tested and a Test Definition are selected during the initialization of ADCS Tools, [Run Test Definition] mode. A pointer to a default Test Definition for a DUT is
included in the DUT Definition, [Calibration] tab.
Create, edit and remove Test Definitions using the Test Editor. Access this
feature using the ADCS Tools[Setup], [Test] or the Main Toolbar, [Edit Test]
button. When the Test Editor is opened, the last accessed Test Definition is
displayed. While in the Editor, use the Editor Toolbar options to create, edit,
view and delete tests.
Sample tests are already included in the Test Definition database as examples.
The Test Editor uses the same editing concepts as the DUT Editor. Only one
Test Definition can be edited at a time. The test scroll bar and the Test Selector
are available to make new test selections. A flashing indicator displays when a
Test Definition is modified or a new definition is created.
Familiarity with test execution sequence is necessary for proper setup of a
Test Definition. Review Section 4.4.2.1 before setting up a Test Definition.
Tests can be edited whenever ADCS Tools is not in an active run mode. Select
[Setup], [Test] to display the Test Editor. Simply changing information in the
Test Editor places the Editor in the edit mode. No specific option needs be
selected to begin editing a Test Definition. Use the [Save] button to store the
edits or press the [Restore] button to return the test to its original state.
Different types of Test Definitions are supported. The choices are:
•Simple Test – Basic test that defines a list of pressure points only.No
macro or changes in reference device during the test are permitted.
•Advanced Test – Can include temperature points. In addition Test Macros
can be used to test a device.
When setting up Test Definitions in ADCS Tools the pressure <Read> and
<Set> device is always <ADCS-601> and cannot be changed.
ADCS Tools uses the engine of COMPASS for Pressure® calibration software to
manage automated testing using ADCS-601-AF. The Support Device Editor is a

Support devices are setup in Support Device Definitions using the Support
Device Definition Editor. Device Definitions define support devices that measure
and produce outputs as well as devices that control in response to target sets. A
Support Device Definition can also allow the device to act as a DUT to allow it to
be tested and calibrated without having to set it up separately as a DUT. A
single support device can provide multiple final outputs and final sets.
The Support Device Editor provides features to create, edit, view and remove
Support Device Definitions from the ADCS Tools database. Access the Support
Device Editor by pressing [Setup], [Support Device] or the Main Toolbar[Device Definition Editor] button. When selected, the last accessed Support
Device Definition displays. To edit an existing Support Device Definition, use the
Editor Toolbar buttons to select the desired definition. Then simply edit the
desired fields. Press the Editor Toolbar, [Save] button to save the changes.
Sample Support Devices are already included in the Support Device database as
examples.
4.4.1.4 TEST OPTIONS (DATA OPTIONS)
ADCS Tools uses the engine of COMPASS for Pressure® calibration software
to manage automated testing using ADCS-601-AF. The Test Options
supported by ADCS Tools are COMPASS for Pressure features. See the
COMPASS for Pressure User’s Manual section on [Tools], [Options] for
complete information on ADCS Tools Test Options tabs. The COMPASS for
Pressure manual is an on-line manual available by pressing the [?] button,
when available, in COMPASS features. It can also be accessed on the
ADCS-601-AF system controller in the COMPASS for Pressure program
group reached using the Windows START button , Programs.
ADCS Tools allows preferences to be set concerning how data is collected and
displayed when running automated tests and operations that occur to conclude a
test. These preferences are set using [Tools], [Test Options].
The [Test Options] form includes five tabs whose functions are describe below.
[Data Grid] Tab
The [Data Grid] tab is used to customize the Data Grid Run Screen that is
available while running tests. The grid can be customized to display only the
desired data field columns while suppressing other columns. The order of the
columns can also be changed. Any test data item logged in the Data File can be
included in any column of the Data Grid Run Screen by using the correct
combination of features. Press the [Default Settings] button to automatically
display the ADCS Tools default data fields.
[Data File] Tab
The [Data File] tab is used to customize the selection of data fields that are
actually logged in the test Data File. The selections do not affect the data
displayed in the Data Grid Run Screen. Although a specific piece of data is not
logged in a test Data File, it can still display in the Data Grid Run Screen.. Only
data actually logged to the Data File can be imported into the Test Data
Database. Press the [Default Settings] button to automatically log the ADCS
Tools default data fields.
[Data Header] Tab
The [Data Header] tab is used to customize the data logged in the header
portion of a test Data File. Header data includes detailed information on the
specific devices used to measure test data. Although header data is the basis of
report information, not all header data is desired. Few ADCS Tools setups will
require all header data. Check the header options relevant to your typical
setups.
[End Test] Tab
The [End Test] tab is used to user preferences affecting operations that occur to
conclude a test sequence.
<Finish point of each cycle> allows the operator to use the ADCS Tools features
to step back in a test to repeat points. Check <Enable repeat for fixed time delay>
and enter a time to allow stepping back for a fixed time after the test ends. Check
<Prompt to repeat> to have ADCS Tools query the operator at the end of a test.
check <No repeat option> to have the test complete without pausing.
Check <Auto generate reports after complete test> to have ADCS Tools
automatically generate a test report using the last report template used when the
test is completed. The <Test Complete> options still display at the end of the test.
Check <Prompt for test notes at the end of complete tests> to have ADCS Tools
prompt the operator to enter notes specific to the test once the test has completed.
4.4.2 RUNNING AUTOMATED TESTS
ADCS Tools uses the engine of COMPASS for Pressure® calibration software to manage
automated testing using ADCS-601-AF. The Run Test functions supported by ADCS
Tools are COMPASS for Pressure features. See the COMPASS for Pressure User’s
Manual Run Modes Section for complete information on running automated tests. The
COMPASS for Pressure manual is an on-line manual available by pressing the [?] button,
when available, in COMPASS features. It can also be accessed on the ADCS-601-AF
system controller in the COMPASS for Pressure program group reached using the
Windows START button , Programs.
ADCS Tools has two automated test run modes. In both run modes, a data file is created to
collect data from the test.
Run Test Definition Activated by selecting [Run], [Run Test Definition] from the ADCS
Tools main run menu. This run mode is to run a Test Definition that
specifies a pre-defined test sequence and test parameters.
Run Manual Test Activated by selecting [Run], [Run Manual Test] from the ADCS Tools
main run menu. This run mode allows any combination of test hardware
and DUTs to be specified. There is no pre-defined test sequence.
Pressures can be set as desired and data can be taken at any time by
pressing the appropriate data acquisition option on the Main Toolbar.
Before activating a run mode, make sure that all instruments that will be used to run are
properly configured and remotely connected to the system controller (host PC). This will
prevent interface time-outs that will interrupt the test initialization process.
4.4.2.1 RUNNING A MANUAL TEST
ADCS Tools uses the engine of COMPASS for Pressure® calibration
software to manage automated testing using ADCS-601-AF. The Run
Manual Test function supported by ADCS Tools is a COMPASS for Pressure
feature. See the COMPASS for Pressure User’s Manual Run Modes Section
for complete information on running automated tests. The COMPASS for
Pressure manual is an on-line manual available by pressing the [?] button,
when available, in COMPASS features. It can also be accessed on the
ADCS-601-AF system controller in the COMPASS for Pressure program
group reached using the Windows START button , Programs.
Use this feature to manually select a DUT and support devices to include in a
test and execute the test without predefined parameters in a Test Definition.
This run mode is useful for running devices when there is no fixed sequence to
be executed. Although, data acquisition is supported, it is not a required part of a
Manual Test. During the test initialization process, the last Manual Test
selections display. These selections can be changed if desired. There are no
requirements to use any specific combination of devices. For example, a Manual
Test can be executed using a temperature controller only. Manual Tests should
be used for trouble shooting device final output setups and running specialized
tests. Run a Manual Test, for example, to verify that a device is working properly
with ADCS Tools or to log “drift” data of a device over time at one point.
To run a Manual Test select [Run], [Run Manual Test]. Test Initialization occurs
in the same manner as when running a Test Definition but no Test Definition
selection is required (see Section 4.4.2.2). After initialization, all remote devices
are automatically polled and output information is displayed on their
run screens. Use the features
on the Data Acquisition section of the Main
respective
Toolbar to create a Data File and log test points. Use features on the Test Conditions Run Screen as well as the individual run screens of the devices to
change the state of the devices.
4.4.2.2 RUNNING A TEST DEFINITION
ADCS Tools uses the engine of COMPASS for Pressure® calibration
software to manage automated testing using ADCS-601-AF. The Run Test
Definition function supported by ADCS Tools is a COMPASS for Pressure
feature. See the COMPASS for Pressure User’s Manual Run Modes Section
for complete information on running automated tests. The COMPASS for
Pressure manual is an on-line manual available by pressing the [?] button,
when available, in COMPASS features. It can also be accessed on the
ADCS-601-AF system controller in the COMPASS for Pressure program
group reached using the Windows START button , Programs.
A Test Definition test has the test parameters and pressure sequence predefined (see Section 4.4.1). To run a Test Definition test, a DUT Definition and
Test Definition must have been created (see Section 4.4.1.1, 4.4.1.2).
To run a Test
Definition
select [Run], [Run Test Definition]. The run process
has three main steps:
Test Initialization: Steps through screens to:
- Select unit of measure. When running a Test Definition, the unit specified
by the Test Definition is always used to log data.
- Specify user.
- Select DUT(s) to be tested. Double click DUTs in the grid to add them to
the list of DUTs to be tested.
- Configure DUT(s). Specifies details specific to the DUT being tested.
- Select Test Definition to be run. By default, the Test Definition specified
in the DUT Definition is selected. Double click the desired Test Definition.
- After the Test Definition has been selected, most ADCS-601-AF users
can press [Finish] to skip remaining initialization steps and go directly to running the test.
Run Test Sequence: Runs leak test (if included) and pressure exercise (if
included) followed by the test points taking data at each point based on the
test data selections. The test parameters are defined by the Test Definition
(see Section 4.4.1.2).
End Test: Presents the Test Notes screen to record test specific notes and
the Test Complete screen with various test conclusion options. Certain
aspects of the test conclusion can be customized using the [Tools], [Test Options], [End Test] tab (see Section 4.4.1.4).
4.4.3 TEST RUN SCREENS
Special run screens are available when running an automated test.
The Data Plot and Data Grid Run Screens are available when running any automated test
for which there is a data file. These run screens visualize test results while the test is
running.
The DUT/Reference Comparison Run Screen is available when running any automated
test, regardless of whether there is a data file. This screen provides real time DUT and
ADCS-601-AF readings and information on the agreement between them.
See Section 4.4.3.1 for information on the Data Plot Run Screen, Section 4.4.3.2 for
information on the Data Grid Run Screen and Section 4.4.3.3 for information on the DUT/Reference Comparison Run Screen.
