Description Of Procedures - GE Druck DPI 610 User Manual

INTRODUCTION
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 inH
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.
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.
