INTRINSIC SAFETY CONDITIONS OF USE

This handbook covers the calibration instructions for both standard
instruments and intrinsically safe models. Intrinsically safe models are
designed to be intrinsically safe when operated in accordance with the
BASEEF A Certification document and schedule which is supplied.

BASEEFA Certificate of Conformity No. Ex 99E2002X

BASEEF A being an Approv ed Certification Body, in accordance with
Article 14 of the Council Directive of th European Communities of 18th
December, 1975 (76/117/EEC) certifies that the apparatus has been
found to comply with harmonised European Standards:

EN 50014: 1992
EN 50020: 1994

and has successfully met the examination and test requirements
recorded in confidential report Number

98(C)0818 (ERA Report Ref.3627/856), dated January, 1999

NOTE: For intrinsically safe models, attention is dra wn to P ages 4/5

of the Certificate of conformity.

General

This publication covers the calibration procedures f or DPI 610 Portable Pressure Calibrator/
Indicators and should be read in conjunction with Druck Publications K213 and K239.

The following key symbols are used in the procedure diagrams which follow and are
repeated here (from K213), to allow this supplement to stand alone. P ages 1 to 7 of K213
and K239 detail the operator controls and general information which is relevant to all
options of the DPI 610 Instrument.

Shaded cursor keys indicate that a combination of these four ke ys,
Up, Down, Left and Right should be used to (e.g.) enter an alpha
numeric value or to select a function.

selection. Shading indicates key operation.

Maximum Instrument Ratings

The following table shows the maximum measurement ratings of the standard instr ument
which should not be exceeded. Pressure overrange (120% of FS) is indicated by the
pressure display flashing. Voltage or current overrange, causes either the voltage or current
display to flash.

,[30V dc (IS)]

Note:

For the DPI 610 AERO version, when the AERO task is selected,the display
flashes if the voltage or current input overranges by 110% of the above maximum
values. The pressure display flashes at altitudes below -3000 ft and above
50,000 ft or at airspeeds greater than 600 kts,depending upon the mode selected.

DPI 610 Calibration Procedures

Introduction

The instrument is supplied by the manufacturer, complete with calibration certificate(s).
The re-calibration interval will depend on the total measurement uncertainty which is
acceptable for a particular application. In order that the instrument remains within the
quoted accuracy, it is suggested that it’s calibration be checked at 90 day inter vals.

The DPI 610 is a very precise measuring instrument and the test equipment and conditions
of test must be suitable for the type of work. The use of a Class A compensated deadweight
tester is essential. The tests should be carried out in a controlled environment by a
competent, trained person.

If, when the accuracy of the instrument is checked, it is f ound to fall outside the specification,
calibration adjustment can be undertaken to compensate errors.

The manufacturer offers a comprehensive and, if required, NAMAS accredited calibration
service.

General Procedures

The following general hints are provided as a guide to calibration procedures.

Do

Use high quality
time before calibration (minimum 1 hour).

Conduct the calibration in a temperature and preferably, humidity controlled environment.
Recommended temperature is 21°C, ±2°C.

Use deadweight testers carefully and away from draughts.
Review and become familiar with the whole calibration procedure before commencing the

calibration process.
Ensure that the instrument is NOT set to BASIC mode. The Instrument’ s calibration routines

are not accessible from this mode. If necessary, use the TASK key to select another mode
(e.g.) ADVANCED.

Repeatable and Linear

pressure sources and allow adequate stabilisation

Calibration Protection

In order to protect against accidental loss,the calibration of this instrument is
protected by a PIN number. Initially, this PIN number is set to 4321. To prevent
unauthorised access to the calibration routines, it is recommended that this PIN

number should be changed at the earliest opportunity(refer to Page 8).

Calibration Procedures

DPI 610

Calibration Check

At the chosen interval, the instrument readings should be compared with a known standard.
Any deviations between the instrument and the standard should be noted, taking due
account of the traceability (accuracy to a National Standard). If these deviations exceed
the published tolerance, or any other suitable chosen performance standard, then the
user may wish to carry out a calibration adjustment.

It is recommended that measurements be checked at 0, 20, 40, 60, 80 and 100% of full
scale on an ascending and descending run. Refer to Tables 1 to 4, pages 27 to 30, for
details of test inputs and tolerances.

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. In these circumstances,the
instrument should be returned to a qualified service agent (refer to pages 22 and 23).

Test Equipment

The following laboratory standard test equipment will be required for the calibration
procedures:-

Using the Calibration Menu

The calibration routines are selected from the Setup menu as detailed on page 8. The
calibration routines are not accessible whilst the instrumement is in BASIC mode. If
necessary therefore,use the TASK key to select another mode (e.g.) ADVANCED before
attempting to access the CALIBRATION mode.

DPI 610 Calibration Procedures

To enter the CALIBRATION mode, press SETUP and select CALIBRATE from the menu
as shown below.

Use a combination of the cursor keys to enter the PIN number (Initially set to 4321) as
shown below. The Up and Dow n keys enter numer als (0 to 9) or (9 to 0) respectively and the
right and left keys shift number position. If the Enter pin prompt disappears before the first
digit is entered, press ENTER to re-display.

Change Calibration PIN Number

The Calibration PIN number is changed from the Calibration Menu. Use the cursor keys to
select CHANGE PIN and proceed as follows.

Note that the new PIN number requires to be entered twice, the second entry being used to
verify the change. If the second PIN number entry differs from the first, the PIN number is
not changed and the following error message is displayed.
