INTRODUCTION
1. PUBLICATION BREAKDOWN
This user instruction manual establishes the standards of operation for the DPS1000 Pitot-
Static Test Set.
Its purpose is to provide sufficient information for the personnel unfamiliar with this unit to
understand it, identify its parts, and operate it in accordance with proper procedures,
operating techniques, precautions and limitations.
Note: The manufacturer has designed this equipment to be safe when operated using the
procedures and instructions detailed in this manual. Do not use this equipment for any
other purpose than that stated, as the protection provided by the equipment may be
impaired.
2. INFORMATION PROVIDED WITH THE TEST SET
In addition to this User Instruction Manual, the Test Set is delivered with the four information
items described below.
A. The identification label, example (Figure 1), located on the front bulkhead of the Test
Set, provides the following information:
Manufacturer Name
Designation of Equipment
Equipment Part Number
Equipment Model Number Equipment Serial Number
Equipment Modification (if applicable) Equipment Options (if applicable)
Figure 1 Identification Label

56-101-01175 Revision I Page | 14
B. The Owner's Warranty Registration card (Figure 2), is to be completed by the owner and
returned to Barfield, Inc. within ten (10) days of purchase to ensure automatic update of
printed matter and validation of warranty.
Figure 2 Owner Warranty Registration Card
C. Each new or re-certified unit is delivered with a Certificate that shows the date when the
unit was tested by the manufacturer, its serial number and when the next certification is
due. This certificate confirms that the unit performed according to its design
specifications.
D. The DPS1000 Limited Two Year Warranty can be seen in Figure 3.
3. RECERTIFICATION
A. The Test Set has a one-year recertification requirement. Maintenance required by this
unit must be performed by qualified technicians in a shop equipped with the necessary
tooling and resources. Contact Barfield for Maintenance and Calibration requirements.
B. At the conclusion of the power up initialization the DPS1000 will display the date when it
was “Last Calibrated” in the format of Day–Month-Year and will provide the user with
the number of days remaining before its calibration due date with a statement of “Cal
due” in ### days format.
CAUTION: Recertification by a calibration/repair shop not possessing the necessary
technical knowledge, documentation, special test equipment, tooling and
standards will adversely affect the accuracy/capability of the DPS1000 for
testing the aircraft, including the demanding Reduced Vertical Separation
Minimum (RVSM) accuracy requirement.
4. SOFTWARE UPDATE
A pop up window will appear every six (6) months on the screen reminding the user to
update the software. Press “continue” to proceed with the update. Please, check
Barfield’s website regularly for the latest software updates and releases. Also, sign up
for automatic updates of Barfield ADTS app.

when connected to a leak tight system.
Specifications are subject to change without notice.

E. Pressure Media
Two internal high reliability electric pumps generate the required pressure and vacuum.
The 4-head vacuum pump is configured to provide each channel (Ps & Pt) with its own
dedicated 2-headed vacuum source. The pressure pump is a single head unit and
supplies both channels (Ps & Pt) with a common pressure supply.
F. Transducers
The Ps channel uses an absolute pressure transducer while the Pt channel uses a
differential pressure transducer.
G. Input Power
Electronic switcher power supply module with auto input voltage detection circuitry for an
A/C input voltage of 100-120/200-240VAC @ 50-60Hz.
H. Fuse Protection
Fuse overload protection is provided by a Miniature Fuse, 5 x 20 mm, Time-Lag T, L, 250
VAC, 4A is installed on the fuse compartment of the power entry module.
Note: For 200-240 VAC Operation, 5x20 mm, Time-Lag T, L, 250 VAC @ 2A is
recommended.

3. INSTRUCTIONS FOR USE
A. With the Barfield DPS1000 Pitot and Static ports connected via the hoses (included) and
mating aircraft adapters (not included) to their respective ports on the aircraft, the user is
able to enter pressures or equivalent aeronautical values using the Test Set’s touch
screen input display to drive the aircraft system to the required points of test.
B. Optionally the DPS1000 Test Set can be controlled using a Wi-Fi enabled tablet (not
supplied) as a wireless remote control device. The tester can be used with either an
Android or iOS tablet. Barfield provides a custom App which is available as a free
download from the Google Play Store and the Apple App Store. The tablet display will
exactly mirror that of the tester so that the transition to remote control is seamless. Please
refer to Appendix E for the Tablet App Wi-Fi Connect Procedure.
C. Please refer to Chapter 4 OPERATIONS for complete operating instructions.
D. Please refer to Appendix D for the Menu Navigation.
