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.
Calibrator versions of this instrument contain pneumatic or hydraulic pressure
generation components to produce pneumatic pressure ranges between -1 to 20
bar and hydraulic pressure ranges up to 400 bar.
Using external electrical connections, the DPI 610 IS and DPI 615 IS intrinsically
safe instruments measure ±30 volts d.c. 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 RS 232
connector to enable downloading of test data to a compatible documenting
system. Six alkaline C size batteries, IEC Type LR14, power the instrument.
Important Notice
Zinc-carbon and zinc-chloride cells must 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 which 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.

selection. Shading indicates key operation.
Exit key, used to clear current menu selection and return to
next menu level above current level. Used as an escape key
from current operation. Shading indicates key operation.

Maximum Instrument Ratings
The following table shows the maximum measurement input ratings of the
instrument which should not be exceeded.
PRESSURE 120% FULL SCALE
VOLTAGE 30 V d.c.
CURRENT 55 mA d.c.
Note 1: The display flashes if the input pressure, voltage or current overrange.
Note 2: Max applied voltage for external loop supply = 30V dc (see Page 8).

DISPLAY
The display section of the instrument basically divides into four distinct sections.
The two main sections of the display are used to display a Measurand (input
parameter) and a Source (output parameter). The remaining sections are used as a
status display area and to define soft key functions. A typical display is shown
below (e.g.),
OPERATOR CONTROLS (Figure 1)
These divide into two groups, the operator/display controls (shown in Figure 1) and
the pressure/vacuum generation components (shown in Figure 2). The operator
controls and a typical display, common to all instrument versions, is shown below.

SOFT KEYS (Fig. 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 (Fig. 1)
The cursor keys consist of a block of four keys, arranged as shown in Figure 1.
They are 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.
