General
1. Introduction
1.1 General
The DPI 610 IS and DPI 615 IS intrinsically safe instruments measure and display pneumatic and
hydraulic pressure applied to the test port.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).
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).
Using external electrical connections, the DPI 610 IS and DPI 615 IS intrinsically safe
instruments measure ±30 V dc and ±55 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 DPI 615
instrument has an RS232 connector to enable downloading of test data to a compatible
documenting system. Six alkaline C size batteries, IEC Type LR14, power the instrument.
1.2 Description of Procedures
The procedures apply to both the DPI 610 IS and the DPI 615 IS instruments unless otherwise
stated. In the procedures in this manual, hard (fixed function) and soft (variable function) key
operations are shown in bold type: TASK and F1. These statements mean press the TASK key
and press the F1 key. Soft key operations can be assigned 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 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 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.
INFORMATION Zinc-carbon and zinc-chloride cells must not be used in this
instrument. Use only the battery types as shown in “Batteries” on page ii.

Operator Controls
1.5 Operator Controls
These divide into two groups, the operator/display controls (Figure 1-1 on page 3) and the
pressure/vacuum generation components (Figure 1-2 on page 5). The operator controls and a
typical display, common to all instrument versions, is shown below.

1.6 Display
The display and key-pad of the instrument divides into four distinct sections. The two main
sections of the display are used to show an input and an output. The remaining two sections show
the status display area and define the soft key functions. A typical display is shown below:

Chapter 1. Introduction
1.7 Hard Key Functions
1.8 Soft Keys
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.
1.9 Cursor Keys
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

Key Function
I/O This key selects the instrument ON and OFF.
SETUPa
a. These key functions are not available in BASIC mode.
The SETUP key provides access to the instrument’s general
configuration parameters that are set-up to certain default parameters
on delivery.
ZERO
The ZERO key zeros either the selected input or output display, only if
the display reading is within 5% of zero. Attempts to zero a larger offset
result in an error message, Zero too large.
INPUTaThe INPUT key selects the input parameter to be displayed.
TASK
The TASK key rapidly configures the instrument for a number of
different types of external device calibration. There are twenty task
configurations available, eleven pre-programmed configurations and
nine user defined configurations.
OUTPUTaThe OUTPUT key selects the output parameter to be displayed.
STOREa
Depending upon how the instrument’s STORE mode is set-up, this key
is used either to store up to 20 display screens in SNAPSHOT mode,
or to manually log a screen in DATALOG mode.
RECALLa
This key recalls a previously stored screen to the display. Depending
on the STORE mode set-up, operation of this key recalls either the
snapshot of a previously stored screen or data log file. In STORE
mode, selection displays the last screen stored. By using the cursor
keys, the operator can scroll either forward or back through memory
locations.
ENTER The ENTER key either enters data (accept entered data), or, in
conjunction with the soft keys, accepts a given selection.
EXIT
The EXIT key operates in conjunction with all the other hard and soft
keys to exit from the current screen or menu level, to the level
immediately preceding it. To quit completely from any menu level,
press EXIT until the MEASURE/SOURCE screen is displayed.
