INTRODUCTION Summary of Functions

General

The DPI 610 is a rugged, portable precision instrument available either as an indicator
or calibrator for use in hazardous areas. Additionally, an intrinsically safe hydraulic
calibrator version (HC) is available.

The instrument is primarily used for calibrating instrumentation and systems over the
range -1 to 20 bar, (HC version to 400 bar). Used in conjunction with e xternal transducers,
the range of the standard calibrator/indicator can be extended up to 700 bar.

The instrument is also capable of sinking an externally supplied current loop up to a
maximum current of 24 mA and measuring dc input voltages of ± 30V and dc currents
of ± 55 mA. Ambient temperature measurement is also provided.

The DPI 610 is powered by six alkaline C-cells and has an RS232 interface.

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 (var iable
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.)

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). A typical diagram is shown below (e.g.).

INTRODUCTION Summary of Functions

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 key s, arranged as shown in Figure 1. They
are designated Up (Ù), Down (Ú), Left (×) and Right (Ø). 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 (Ø) cursor keys will switch between pages.
