INTRODUCTION Summary of Functions

General

The versions of the DPI 610 and DPI 615 instruments are: pneumatic indicator, pneumatic
calibrator, hydraulic calibrator and low pressure pneumatic calibrator. All instruments
measure and display pneumatic and hydraulic pressure applied to the test port or to an
externally connected pressure sensor. Pressure measurement can be absolute, gauge
and sealed gauge and in ranges from 2.5 mbar to 700 bar (1.0 inH

The calibrator versions of this instrument contain pneumatic or hydraulic pressure
generation components to produce pneumatic pressure ranges between -1 to 20 bar
(-14.5 psi to 300 psi) and hydraulic pressure ranges up to 400 bar (6000 psi).
The electrical connections, on the front of the instrument, enable the instrument to
measure ±50 volts d.c. and ±55 mA and produce 10 volts d.c. or 24 volts d.c. and a
maximum of 24 mA. An integral sensor provides measurement of ambient temperature.
Additional sensors (option B1) connect to an external connector and extend the pressure
measurement range and include differential pressure measurement. The instrument has
an RS232 connector to enable uploading of test data to a compatible documenting
system. The DPI 615 has the ability to download, from a PC, pre-defined calibration and
test routines. Six alkaline C size batteries or (option A) rechargeable batteries with a
charger/adaptor, power the instrument.

Important Notice

Zinc-carbon and zinc-chloride cells should NOT be used in this instrument.

Use only the battery types as shown in the table on page 7.

Downloading Procedure Files (DPI 615 instruments only)

Complete test procedures may be downloaded from a PC to the DPI 615 instrument via
the RS232 port. A procedure consists of a number of Druck Universal Command
Interface (DUCI) commands that are usually assembled by a linking management
software application (e.g.) Druck Intecal.

Before downloading a procedure, the instrument must be in the REMOTE mode. To place
the instrument into REMOTE mode, proceed as follows:

• Connect the instrument’s RS232 port to a free COM port on a PC.

• Ensure that the COMMS parameters of the PC match those of the instrument (refer to
page 39).

• Ensure that the instrument is not already running a procedure. If it is, quit the
procedure.

• Download the procedure. Procedures are stored in the Data Log directory.

The following sequence shows a typical download sequence that starts with the
instrument in LOCAL mode.

After the procedure file has been downloaded, the instrument is usually returned to the
LOCAL mode by the last command in the procedure file. If the instrument remains in
REMOTE mode, switch it OFF and ON to reset it.

K415 Issue No. 1 42

Calibration

General

The instrument is supplied by the manufacturer, complete with calibration certificate(s). A
calibration period of 12 months is recommended. The actual calibration interval
depends on instrument usage and the total measurement uncertainty acceptable for the
specified application.

The DPI 610 and DPI 615 are very precise measuring instruments and the test equipment
and conditions of test must be suitable for the type of work. A Class A compensated
deadweight tester must be used. The calibration check and calibration adjustment
should be carried out in a controlled environment by a calibration technician*.

The manufacturer offers a comprehensive and, if required, UKAS or NIST accredited
calibration service.

* A calibration technician must have the necessary technical knowledge,

documentation, special test equipment and tools to carry out the calibration work
on this equipment.

Calibration Check

At the chosen calibration interval, the instrument readings should be compared with a
known pressure standard.
The recommended method starts at 0, increasing in 20% steps to 100% full-scale and
then decreasing in 20% steps to 0.
Note any deviations between the instrument and the pressure standard and consider
traceability (accuracy to a National Standard).
If, after a calibration check, the results exceed the tolerance in the specification (or other
suitable performance standard), carry out a calibration adjustment.

Calibration Adjustment

If the instrument is operating correctly, only zero and full-scale calibration will vary. Any
excessive non-linearity or temperature effects indicate a fault. The instrument should be
returned to a qualified service agent.

Guide to Calibration Procedures

• Use high quality Repeatable and Linear pressure sources and allow adequate

thermal stabilization time before calibration (minimum 1 hour).

• Conduct the calibration in a temperature controlled and preferably, humidity
controlled environment. Recommended temperature is 21°C, ±2°C (70°F, ±4°F).

• Use deadweight testers carefully and away from draughts.

• Review and become familiar with the whole calibration procedure before
commencing the calibration process.

• The calibration routines cannot be accessed when the instrument is in BASIC mode.
Use the TASK key to select another mode (e.g.) ADVANCED before accessing the
CALIBRATION mode.

Bleeding the System (Figure A2)

Before any measurements can be made, the hydraulic system needs to be primed and
bled free of air. During the following operations, prepare for fluid spillage and provide a
suitable receptacle for collecting the spillage.

1. Prepare for use as detailed on page 62.

2. Fill a suitable container with clean hydraulic fluid and place the bleed hose assembly

(1) connected to the priming port into the fluid.

3. Open the UUT bleed valve (5) and, if possible, fit a hose to the bleed point and locate

the hose end in a container of the same hydraulic fluid.

4. Use the priming pump (2), to pump hydraulic fluid into the instrument and the

connected system. Monitor the hydraulic fluid level, ensuring that the bleed hose
assembly (1) stays below the fluid level and is not allowed to suck in air. Top-up
hydraulic fluid level as necessary.

63 K415 Issue No. 1

Hydraulic Calibrator Versions Operation

5. Continue use of the priming pump (2) until only hydraulic fluid and no air is expelled

from the bleed point.

6. Close the UUT bleed valve (5) when the priming pump (2) is at the bottom of its stroke

(fully pushed in) and slowly wind out the screw-press (3) to its fullest extent to draw

).

Note: When hydraulic fluid is compressed and flows through a restriction, there is an

increase in temperature that affects the pressure. Allow sufficient time for this
pressure reading to stabilize before recording or logging a reading.

3. After testing, reduce the pressure in the system to zero by turning the screw-press

counter clockwise. Before disconnecting the UUT, open the isolation valve.

4. Remove the connection to the UUT and fit a blanking plug into the instrument’s

pressure port. Clean any spilt fluid off the instrument case.

Draining the Hydraulic Fluid (Figure A3)

To drain the hydraulic fluid from the instrument, proceed as follows:

1. Turn the isolation valve (4) fully counter clockwise. Turn the instrument onto the left

hand side (pressure port nearest to the work bench). Place receptacle below the
pressure port to collect hydraulic fluid.

2. Drain the system by slowly winding in the screw-press (3) and then depressing the

priming pump (2) plunger to expel any fluid remaining in the instrument.

3. If necessary, apply an air line to the priming port to clear any remaining fluid out of

the instrument.

Low Pressure Calibrator Versions

Introduction (Figure B1)

These versions of the DPI 610 and DPI 615 Calibrator measure and display low
differential pneumatic pressures applied to the pressure port. The differential pressure
measurement ranges can be: 2.5, 12.5, 25, 50, 75 or 150 mbar (1.0, 5.0, 10.0, 20.0, 30.0
and 60.0 inH

For low volume external systems or devices, test pressures are generated by an integral
two-stage (coarse/fine) volume adjuster. For larger volume external systems or devices,
test pressures are generated by an external, hand-operated, pneumatic pump.
An internal pressure limiter operates at 120% of the full-scale, positive or negative test
pressure. If this over-pressure remains for more than approximately 1 second, a valve
within the calibrator opens, directly connecting the positive and negative pressure ports
together, to release the excess pressure. When the pressure decreases to within the
operational limits, the valve automatically closes to allow normal operation to restart.

This section should be read in conjunction with the operation and calibration sections of
this manual. All the operational features described for the standard calibrator are
available on this low pressure version of the calibrator.

Preparation for Use Low Volume Systems

Caution: This calibrator can produce a maximum differential pressure of 120%

full-scale. Make sure any component connected to this calibrator can
withstand this maximum differential pressure.

 Use the TASK key to set-up the calibrator for an appropriate test:

Example:

P-DISPLAY.

 To record test data for other tasks, set-up the calibrator to either Data log or

Snapshot as required, refer to pages 30 or 31.

 Fit an appropriate pressure fitting to both the positive (+) and negative (-) ports

using a bonded seal as shown in Figure B2. Ensure that both fittings are tight.

 To generate pressure, start with the volume adjuster wound fully out.

To generate vacuum, start with the volume adjuster wound fully in.

 Ensure that the vent valve is open (fully counter-clockwise).

 Connect the device or system under test to both the reference (-) and the

pressure port (+). Connect the ribbed arm of the double tubing to the high (+)
pressure input of the device under test.

Note: To minimize temperature effects, always use double tubing, separating the
arms of the tubing only by the minimum amount necessary to make the pressure
connections. A typical application, P-DISPLAY, showing test connections to a
Magnehelic pressure gauge are shown in Figure B2.

calibrators only, switch on Cal Mode (refer to pages 11, 34 and 35).

 Turn the volume adjuster clockwise to set-up any additional test pressures

required. The recommended method starts at 0, increasing to 10%, 25%, 50%,
75% and 100% full-scale and then decreasing to 75%, 50%, 25%, 10% and 0.

Note: To release the output pressure at any point during a test or series of tests,

open the vent valve. Allow sufficient time for the connected system to vent
(very important when connected to larger system volumes, >0.25 litres [15
cubic inches]).

Preparation for Use with Larger Volume Systems

 Set-up the calibrator to record the test data, using either Data log or Snapshot

facilities refer to pages 30 or 31. If required, and for DPI 615 calibrators only,
switch on Cal Mode (refer to pages 11, 34 and 35).

 Fit the appropriate pressure fitting to both the positive (+) and negative (-) ports

using a bonded seal as shown in Figure B3. Make sure that both pressure fittings
are tight.

 Turn the volume adjuster (counter-clockwise) to approximately half-way

(approximately 30mm (1”) of thread showing).

 Make sure that the vent valve is open (fully counter-clockwise).

 Connect the hand-pump and tee-piece as shown in Figure B3. Connect the

device or system under test to both the reference (-) and the pressure port (+) as
shown. Connect the ribbed arm of the double tubing to the high (+) pressure input
of the device under test.
