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 inH2O to 10000 psi).
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.
Description of Procedures
In the procedures outlined in this user guide, hard (fixed function) and soft (variable
function) key operations are shown in bold type (e.g.) TASK and F1. These statements
mean press the TASK key and press the F1 key. Soft key operations can be allocated to
both the F1 and F2 keys. Where a specific soft function is referred to it is written in bold
italics (e.g.) PROCESS.
This instrument has a number of operating modes that are described in a simplified form
in the following sections. Diagrams accompanying the procedures give typical selection
sequences and shaded controls indicate that this control key should be pressed in the
appropriate sequence. Diagrams should be read from left to right, top to bottom where
appropriate. A shaded display soft box indicates that the function key immediately
below that soft box should be pressed (either F1 for the left hand soft box or F2 for the
right).
In the above diagram the following key sequence is indicated.
(a) Press the F2 key (the key immediately below the
PRESSURE UNITS
soft box).
(b) Use the
Up
and
Down
cursor keys (only) to select the required option. (If all keys
shaded, use all these keys to select or enter data).
(c) Press the ENTER key.

SOFT KEYS (Figure 1)
Three soft keys, designated F1, EXIT and F2, are situated immediately below the display
as shown below. These keys have their function allocated by the instrument software
which is indicated in the bottom of the display (Voltage for F1 and Units for F2 in this
example). They are used to select menu (program) options and are fully described under
the appropriate section headings.
CURSOR KEYS (Figure 1)
The cursor keys consist of a block of four keys, designated up , down , left and
right . In programs where options need to be selected from a list, (e.g.) the TASK
selection program, the up and down cursor keys are used to highlight one of the
options, from which it can be selected by the ENTER key. In TASK mode, where more
than one page of options are provided, the left and right cursor keys will switch
between pages.

Note: After fitting a rechargeable NiCad battery pack the display may show the battery
low indication caused by the battery pack not being fully charged. Use the power
adaptor/charger to fully charge the pack.
Switching On
Press the I/O switch on the front panel and proceed as follows.
The first time the instrument powers up, it will be in BASIC mode with the main screen
displaying voltage in the input display area and pressure in the output display area. To
switch to CURRENT as input, press F1 as shown. Similarly, F1 to return to VOLTAGE.
Note: No other keys are active in this mode and the instrument can only be reconfigured
by pressing the TASK key and selecting another mode.

TASK key
The TASK key is used to set-up the instrument for a number of specific types of test.
There are two modes BASIC and ADVANCED and nine other specific types of test that
automatically configure the instrument on selection from the TASK menu. The tasks
available under the TASK menu are held on three pages shown below. To select a task
from the menu, press the TASK key, position the cursor over the required task and press
the ENTER key as shown below. Use the right/left cursor keys to switch between pages.
Using Task Functions
Specific tasks are selected as shown above. The following diagrams show how to
connect the unit under test (UUT) for each task selectable under the TASK menu.
Input and output units, where applicable, can be selected by pressing either the INPUT or
OUTPUT keys as shown below. The output key also provides the facility of turning the 24V
output supply ON and OFF. When not in use, the 24V supply output should be turned OFF
to conserve battery power.
